A Selection of Fossils from the ‘March Formation’ in Lanark County, Ontario - A Correction
I was speaking with my daughter on Thursday and mentioned to her that there were a few things on my blog that were not correct. She chimed in “Fake News!” That convinced me to go back, correct and improve my identification of fossils shown in the photographs that accompanied my September 13, 2013 blog posting. These are my suggested changes.
1. Bedding Parallel Burrows and Bioturbation in a bed close to the top of the quarry. Likely early Cambrian (or Ordovician).
2. The Trace Fossil Helminthopsis. Simple cylindrical, curving burrows roughly parallel to bedding plane. Possibly Ediacaran, Cambrian or Ordovician in age.
3. Larger, rougher, cylindrical, curving burrows roughly parallel to bedding plane. Possibly a worm burrow like Helminthopsis, but more likely arthropod burrows of Cambrian or Ordovician age.
4. Branching, overlapping, possibly interpenetrating, roughly parallel to bedding plane, some plant like. Three of the photos probably record Ediacaran microbial mat destruction textures, with the first, second, and fifth photographs possibly show a reticulate pattern of petee ridges, with the ridges in the first flattened, or simply sand cracks in a microbial mat. The second last photo shows a disc with stalk (below the ruler) and a number of spindle shaped objects that are potentially Ediacaran rangeomorphs. The last photo shows numerous spindle shapes that are possible Ediacaran rangeomorphs (note the medial line on three of the spindles), but the spindle shape is also consistent with examples reported by others as being petee ridges (e.g, see Eriksson et al., 2007, figures 4(c)-8B & 4(c)-9). The fourth photo might show Ediacaran vegetation (not rangeomorphs as there is no fractal construction) but is more likely to be a badly ripped microbial mat. I cannot identify the structure in the third photo, but note that the same texture is shown in the first four photos on my August 20, 2014 blog posting.
5. Concentric discoid structure. More likely the Ediacaran holdfast Aspidella than medusae.
6. Concentric discoid structures. The second and third are likely the Ediacaran holdfast Aspidella. The first might also be. The fourth is likely Ediacaran, and might be Nemiana or Chuaria or Nimbia occlusa.
7. A Congestion/Colony of Multiple Ediacaran discoid holdfasts. Likely Aspidella. Note that the second photo shows an Ediacaran rangeomorph structure (Bradgatia?) above the 4 1/4 to 4 1/2 inch marks on the ruler.
8. ‘ Lindt Truffles’ (circular, about the size of the candy, with a thin 2-4 mm rim and a different coloured centre) is the name that I used when talking about this structure with the quarry manager in 2013. They are common at the quarry. Possibly the Ediacarn fossil Chuaria or Beltanelliformis (=Beltanelloides, Nemiana). Interestingly the smaller ones can often appear close to a spiral form, and while looking a bit like Gastropods are not as spiral as Arenicolites spiralis, Billings 1872 that was reported to have been associated with Aspidella in Newfoundland.
9. Thin Film, barely there. Sack like. (algae?) (an Ediacaran Tawuia-like fossil?)
10. In about 2013 I sent these photographs to paleontologists who study Paleozoic fossil plants. I received the reply that the photographs likely show a trace fossil. In about 2013 I sent the same photographs to a paleontologist who has written extensively on Ediacaran and Cambrian trace fossils, who replied that it was likely a plant. My best guess is that it is algae or analogous to algae. Some linear grooves might be tool marks resulting from the blasting.
11. Stromatolite (Dr. Al Donaldson's identification while touring the quarry.)
In my September 13, 2013 posting I stated “The only shelled fossil that I’ve found (and I’ve only found broken parts of it) is likely a Gastropod, and Gastropods have been found in the March Formation.” That statement is wrong. I found broken parts of a spiral form that I mistakenly identified as a Gastropod. I more likely found the Ediacarn fossil Chuaria or Beltanelliformis (=Beltanelloides, Nemiana).
I also no longer believe that Potsdam sandstone outcrops at the quarry. It is Precambrian sandstone of Ediacaran age.
I apologize if I have misled anyone.

Ontario Geological Survey Summary of Field Work and Other Activities, 2018
In December , 2018 the Ontario Geological Survey released its Summary of Field Work and Other Activities, 2018 (OFR 6350) for electronic distribution. It can be downloaded from
http://www.geologyontario.mndm.gov.on.ca/mndmaccess/mndm_dir.asp?type=pub&id=ofr6350
There are four papers of interest to those in Eastern Ontario, two dealing with Precambrian Geology and two with Paleozoic Geology:
Precambrian Geology – Proterozoic and Grenville Province
14. Project SO-17-001. Precambrian Geology and Mineral Potential of the Carleton Place Area, Grenville Province, by R.M. Easton, pages 14-1 to 14-10
15. Project SO-18-001. Precambrian Geology of the Renfrew Area, Northeastern Central Metasedimentary Belt, Grenville Province, by M. Duguet, pages 15-1 to 15-9
Paleozoic Geology and Energy Studies
22. Project SO-18-006. Paleozoic Geology of Eastern Ontario: Ottawa Area, by C. Béland Otis, pages 22-1 to 22-10
23. Project SO-18-005. Identification and Mapping of Alkali–Carbonate Reactive Layers in the Gull River Formation, Near Kingston, Ontario by K.E. Hahn and C.A. MacDonald, pages 23-1 to 23-8
Below I mention what I found to be the highlights of each report.
Dr. Michael Easton mentions:
• “Mafic metavolcanic rocks and associated fine- to medium-grained foliated gabbro sills appear to have been deformed and metamorphosed before, rather than during, emplacement of the Lavant gabbro and associated felsic intrusive rocks.”
• Peraluminous sapphirine has been found. “Peraluminous sapphirine is typically associated with ultra-high temperature metamorphism (>1000C, >8 kilobars).” This is the first reported occurrence from the Central Metasedimentary Belt of the Grenville Province.
• “Most of the major faults shown on the Paleozoic geology map of Williams and Wolf (1984) located solely in Precambrian rocks present in the western half of the Carleton Place map area could not be validated by geology or geophysics.”
• The report contains a colourful simplified geological map of the Carleton Place and southern Arnprior map areas.
• “Work in 2018 indicates that clean, high brightness, low silica content calcite and dolomite marbles are not restricted to the lower metamorphic grade portion of Sharbot Lake domain west of the Clayton shear zone, but they also occur at much higher metamorphic grades between the Maberly shear zone and the Wolf Grove structure, and in the area between the Pakenham and the Wolf Grove structures.” In the long term this could be important for Lanark County’s economy as high-purity marble products have been produced from marble mined at Omya Canada Inc.’s quarry at Tatlock and refined at Omya’s plant on Highway 7 just west of Perth for more than 30 years.
Dr. Manuel Duguet mentions a “newly discovered lithostructural unit, provisionally named the Calabogie klippe, is exposed south of the Madawaska River”, which is “mostly composed of amphibolites and calcite marbles.” His report contains a simplified geological map of the area.
Catherine Béland Otis is continuing her a multi-year project of mapping the Paleozoic geology of eastern Ontario, and addressing the fact that “in the last 3 decades, almost all Cambro-Ordovician stratigraphic units of eastern Ontario have been the focus of academic research. These studies have introduced new stratigraphic units (or re-introduced old terms), revised geological contact definitions and/or proposed the application in Ontario of stratigraphic terminology used in adjacent jurisdictions instead of the current OGS nomenclature.” Her Figure 22.2 deals with competing terminologies for Paleozoic strata in eastern Ontario, with her left Column providing the nomenclature currently used by the Ontario Geological Survey , while the column on the right is the nomenclature proposed in more recent publications.
In the summer of 2018, the OGS started geological mapping of the Ontario portion of the
Ottawa National Topographic Sheet, and Catherine Béland Otis provides a concise summary of each rock unit mapped in the Ottawa area. Based on the terms used in her report it appears that the OGS will adopt Lowe and Arnott’s breakdown of the Potsdam Group into three formations, but may not change Nepean to Keeseville for the uppermost unit.
Katherine E. Hahn and C.A. MacDonald are dealing with an interesting problem. While the Gull River and Bobcaygeon formations are being used as a source of concrete aggregate in Ontario “[b]oth of these units contain lithologies that are known to cause alkali aggregate reaction, a chemical reaction that occurs in either mortar or concrete between the hydroxyl associated with the alkalis sodium and potassium from Portland cement or other sources, with certain mineral phases in the coarse or fine aggregates.” This is a concern because it can cause premature deterioration of concrete.
The two main questions that their project aims to address are :
1. Can alkali–carbonate reaction (‘ACR’) strata be mapped at the regional scale and predicted based on sedimentology and stratigraphy?
2. What are the geological controls on the distribution of ACR strata?
Field activities were conducted in 2018 with visits to 21 quarries (active and inactive) and 135 outcrop localities. They have focused on “a green marker bed in the Gull River Formation (probably stratigraphically equivalent to the middle member in the Kingston area) that is used to constrain where the alkali reactive beds begin; generally, aggregate for concrete purposes is not extracted within 1 m above the green bed and never below it.” Further investigations are planned.

The Trace Fossil Helminthopsis in Sedimentary Rocks of Lanark County , Ontario
The above photograph (SAM_0037) was taken of a loose specimen collected at Tackaberry’s quarry about three miles north of Perth. I believe it to be the trace fossil Helminthopsis, which has been described by Wetzel & Bromley (1996) as “Simple, unbranched, elongate, cylindrical tube with curves, windings, or irregular open meanders.”
I have been able to name the trace fossil Helminthopsis since the fall of 2012 when I noticed a nearly identical specimen displayed on a web page of the Miller Museum of Geology, Queen’s University at Kingston, under the heading ‘The Ediacaran of Canada’. Excitedly I sent an email to the museum curator with the above photo claiming that I had found the Ediacaran fossil Helminthopsis in Lanark County. Regrettably I received back an email telling me that this trace fossil cannot be used to determine the age but the environment.
Wetzel & Bromley (1996) mention that “Helminthopsis is a feeding burrow produced normally at shallow depth within sediment rich in benthic food.” Buatois, Mángano, Maples and Lanier (1998) describe it as a grazing trace while Mangano and Buatois (2003), describe it as a simple grazing trace. The Miller Museum of Geology’s web site stated that “It is generally agreed that simple burrows and trace-fossils (such as Helminthopsis pictured to the left) found in Upper Precambrian rocks were made by primitive worms. These worms... survived the extinction event and took part in the greatest evolutionary event in Earth’s history: The Cambrian “Explosion”.
A search on the internet shows that Helminthopsis has been recognized in many rocks aged Cambrian and younger. For Example, Helminthopsis has been recognized in the Fortunium (lower Cambrian) rocks of Iran (Shahkarami, 2016), Upper Cambrian/Lower Ordovician rocks of Newfoundland (Fillion, and Pickerill, 1990), early Silurian rocks of New Brunswick (Kim, Pickerill, Wilson, 2000), shales of Switzerland (Heer, 1877), the Carboniferous of Argentina (Mángano and Buatois, 20013), the Carboniferous rocks of Alabama (King, Stimson, Lucas, 2018) , upper Carboniferous rocks of Kansas (Buatois, Mángano, Maples and Lanier, 1998), Oligocene rocks (de Gibert and Sáez, , 2009), and Eocene rocks of the San Joaquin Valley, California (SJVG, 2019).

Fossil Ripple Marks in Rocks Near Perth Ontario
Fossil ripple marks were formed by the movement of water or wind over sediment, and are useful for determining the direction of the current or wind, and the environment in which the ripples were formed. For example, geologists and paleontologists can tell the direction of water flow and wind flow from the shape of asymmetric ripples, and from symmetric ripples deduce oscillating directions of water flow which suggests a near beach environment. They can also differentiate between ripples formed by water and ripples formed by wind.
Below are photographs of loose specimens and bedrock at Tackaberry’s quarry located on highway 7 about two miles north of Perth, in Lanark County, Ontario. The photographs show fossil ripple marks, primarily symmetric ripples, that originally formed under water. (However, when I was taking photographs I was mainly looking for ripples with curvilinear cracks in the ripple troughs or shrinkage cracks on the ripples. I was not looking for asymmetric ripples.)
The first photo shows ripples in bedrock at the quarry. Sam_27
The remainder of the photographs are of loose specimens resulting from blasting at the quarry.
An interesting point about photographing loose specimens is that it is as likely that I photographed a bed top as a bed sole.
The next two photos show a bed sole and a bed top of symmetric ripples, though probably not parts that match. Sam_62 and Sam_63
The previous photo also shows the curvilinear cracks that formed in many ripple troughs in specimens found at the quarry.
The next photos show a crust on the ripples, that might result from a microbial mat: Sam_133 (a bed sole) and 135 (a bed top).
.
The next photo show a number of superimposed thin beds with symmetrical ripples on the top beds and symmetrical ripples on the lower bed, with the two sets of ripples going in different directions. Sam_151
The next photos, Sam_153 and 152, are close ups of the above photo, the second showing polygonal shrinkage cracks in the ripples.
Below is an extract from Ontario Geological Survey Map P. 2724 entitled Paleozoic Geology Perth Area, issued 1984, geology by D. A. Williams and R. R. Wolf, 1982, on which I’ve plotted the location of Tackaberry’s quarry and the location of the Glen Quarry where Climactichnites wilsoni was found by Dr. James Wilson of Perth, and named by Sir William Logan after Dr. Wilson. The map puts Tackaberrry’s quarry within the March Formation, which is thought to be Lower Ordovician in age, and places the Glen Quarry within the Nepean Formation of the Potsdam Group .
The upper bar scale on the map is in tenths of a mile and 1 mile. The lower bar scale is in tenths of a kilometre and 1 kilometre. The major faults are shown on the map, with the arrow indicating the downthrown side. The legend shows that the letters PC on the map indicate undifferentiated Precambrian igneous and metamorphic rocks, that the number 2 on the map indicates Nepean Formation sandstones of the Potsdam Group, and that the number 3 on the map indicates March Formation interbedded quartz sandstone, sandy dolostone and dolostone.
On the map I’ve also shown the approximate location of the Hands quarry that was described in 1931 by Dr. Morley Wilson of the Geological Survey of Canada. While the Hands quarry is only two miles south of Tackaberry’s current quarry on Highway 7, and both are mapped as March Formation, the rocks at the two quarries are quite different. The map shows that a fault separates two blocks that have been mapped as March formation, with Tackaberry’s quarry falling on the western block and Hands quarry falling on the southeastern block. The rocks at Hands quarry would be considered typical March Formation (or, more accurately, typical of parts of the March Formation). I mentioned in my September 24, 2012 blog posting that the rocks at Tackaberry’s quarry differ from other areas that have been mapped as March Formation. I still hold that view. The rocks at Tackaberry’s quarry are not typical March Formation, and there might only be a veneer of March Formation.
In my September 24, 2012 blog posting I suggested ‘Drummond sequence’ for the block where Tackaberry’s quarry is located and suggested that the rocks appear to be much older than typical March Formation rocks. I also mentioned that Sir William Logan had reported that he had found Climactichnites and Protichnites at a quarry in Lot 6, Concession 3, Drummond Township, which would fall within the Drummond Sequence. However, my subsequent investigations (see my blog postings of January 31, 2013 , February 11, 2013 and May 6, 2013) showed that the Glen quarry is actually on Lot 3, Concession 3, Drummond Township, and falls in Cambrian Potsdam sandstone rather than within the Drummond sequence that has been mapped as Lower Ordovician March Formation. On the below map I plotted the Glen quarry on Lot 3, Concession 3, Drummond Township on property owned by the Glen family at the time Dr. James Wilson found the tracks that Logan named Climactichnites wilsoni, and where I found a small quarry.
Dr. Morley Wilson is, I believe, the only person to have written a paper devoted to Ripple marks near Perth, Lanark County. In a short paper published in 1931in the Canadian Field-Naturalist he described ripple marks in the March Formation (known in Dr, Morley Wilson’s time as the “Transition Beds”) and included photographs of the ripple marks. The ripple marks occurred in a quarry “on the farm of Mr. H. J. Hands, Lot 10, Concession II, Drummond Township, Lanark County”. Morley Wilson also mentions that “ The quarry lies about 3 miles northeast of Perth and 300 yards north of the second line of Drummond which forms a part of the original stage road from Perth to Ottawa, ...”. The second line of Drummond is more commonly called the Franktown Road and is shown on maps as County Road 10. Jim Hands and his son Trevor both own property on that lot and Concession, and Jim’s property would be familiar to many Lanark residents as Jim and Trevor are well known auctioneers, and Jim has held many an auction on his property.
Morley Wilson mentions that the ripples occur in thin beds on the Hands quarry floor “everywhere throughout the entire extent of the quarry which is over 200 feet long and 100 feet wide and throughout a range of about 14 inches. The total thickness of strata exposed in the quarry face is about 5 feet. This consists of thin bedded sandy dolomitic limestone, in which beds or zones of white limestone up to 1 inch thick are intercalated sparingly near the top but more abundant near the bottom.”
Morley Wilson also mentions that “The sandstone of ... the Transition Beds is ripple marked in many places, the ripples being for the most part of the unsymmetrical type. The greater part of the ripples trend northeast-southwest or east-west and the steeper side of the crests of the ripples are on their south-east or south sides indicating that the current by which they were formed came from the north-west or north.”
D. A. Williams (1991) of the Ontario Geological Survey states that “The March Formation consists of interbedded quartz sandstone, dolomitic quartz sandstone, sandy dolostone, and dolostone.... Shaly partings occur throughout the formation, and glauconitic partings are present in the dolostones and sandy dolostones. ... Quartz sandstones of the March Formation ... are thinly to thickly bedded, fine to coarse grained, and well sorted. The sandstones range in colour from white to light grey, brown, reddish brown, and green; and weather white to light grey and brown to reddish brown. Small brown-weathering spots are common, and are the result of diffusion into the surrounding pore spaces of iron derived from detrital pyrite, magnetite, or ilmenite grains. The quartz grains are subrounded to well rounded. ... Crossbedding, ripple marks, and burrows are common. The dolomitic quartz sandstones and sandy dolostones are light to medium brownish to bluish grey in colour, and weather brownish grey to buff to reddish brown. They are thinly to thickly bedded and contain finely to medium crystalline carbonate and well rounded, fine to coarse grained quartz sand. Some dolomitic sandstone beds are calcareous, and some sandy dolostone beds are calcitic.
...
The March Formation was deposited in a supratidal to subtidal environment. Supratidal to intertidal deposition and hypersalinity are implied by calcite-filled vugs (originally sulphate nodules) and algal lamination in the dolostones. Intertidal deposition is implied by bipolar crossbedded quartz sandstone containing discrete vertical burrows. Subtidal deposition is indicated by highly bioturbated dolomitic quartz sandstone (Bond and Greggs 1973, p.1147-1150). A similar environment was inferred for the Theresa Formation of adjacent New York State by Selleck (1984).”
Williams’ description would cover the rocks of the Hands’ quarry (sandy dolomitic limestone), but is not apt for the majority of rocks of Tackaberry’s quarry as cross-bedding is not common, the burrows are confined to the top beds, there are no calcite-filled vugs, and there is little dolostone in Tackaberry’s quarry. In addition, finding the Ediacaran holdfast Aspidella in the rocks tells against the rocks being Lower Ordovician March Formation.
Below I’ve provided a few references to water ripples and wind ripples. If the reader is going to read one reference in addition to Morley Wilson’s paper, it should probably be Kindle (1917). That said, Evans (1942) makes the important point that “The size of wave-formed ripple marks depends on the depth of water and the size of the generating waves. With waves of a given size, the deeper the water the smaller the ripple marks; with a given depth of water, the smaller the waves, the smaller the size of the ripple marks.”

Postscript (March 19th): It has always impressed me that Sir William Logan was able to identify both water ripple marks and wind ripple marks in the Potsdam sandstones at Beauharnois where he found Protichnites tracks, and that he concluded that the creature “which impressed the [Protichnites] tracks at Beauharnois must have been a littoral animal.” See: Logan (1860), where he named Climactichnites Wilsoni; and Logan (1863), The Geology of Canada. It is also worth noting that Logan (1863) provides various measured sections of Potsdam sandstone, including a section from Beauharnois in the vicinity of Henault’s field (1863, pages 105-106), where he describes the beds and indicates where ripple marks, wind marks, Protichnites tracks and Scolithus occur.

Below are photographs of loose specimens and bedrock at Tackaberry’s quarry located on highway 7 about two miles north of Perth, in Lanark County, Ontario. The photographs show fossil ripple marks, primarily symmetric ripples, that originally formed under water. (However, when I was taking photographs I was mainly looking for ripples with curvilinear cracks in the ripple troughs or shrinkage cracks on the ripples. I was not looking for asymmetric ripples.)
The first photo shows ripples in bedrock at the quarry. Sam_27
The remainder of the photographs are of loose specimens resulting from blasting at the quarry.
An interesting point about photographing loose specimens is that it is as likely that I photographed a bed top as a bed sole.
The next two photos show a bed sole and a bed top of symmetric ripples, though probably not parts that match. Sam_62 and Sam_63
The previous photo also shows the curvilinear cracks that formed in many ripple troughs in specimens found at the quarry.
The next photos show a crust on the ripples, that might result from a microbial mat: Sam_133 (a bed sole) and 135 (a bed top).
.
The next photo show a number of superimposed thin beds with symmetrical ripples on the top beds and symmetrical ripples on the lower bed, with the two sets of ripples going in different directions. Sam_151
The next photos, Sam_153 and 152, are close ups of the above photo, the second showing polygonal shrinkage cracks in the ripples.
Geologic Map
Below is an extract from Ontario Geological Survey Map P. 2724 entitled Paleozoic Geology Perth Area, issued 1984, geology by D. A. Williams and R. R. Wolf, 1982, on which I’ve plotted the location of Tackaberry’s quarry and the location of the Glen Quarry where Climactichnites wilsoni was found by Dr. James Wilson of Perth, and named by Sir William Logan after Dr. Wilson. The map puts Tackaberrry’s quarry within the March Formation, which is thought to be Lower Ordovician in age, and places the Glen Quarry within the Nepean Formation of the Potsdam Group .
The upper bar scale on the map is in tenths of a mile and 1 mile. The lower bar scale is in tenths of a kilometre and 1 kilometre. The major faults are shown on the map, with the arrow indicating the downthrown side. The legend shows that the letters PC on the map indicate undifferentiated Precambrian igneous and metamorphic rocks, that the number 2 on the map indicates Nepean Formation sandstones of the Potsdam Group, and that the number 3 on the map indicates March Formation interbedded quartz sandstone, sandy dolostone and dolostone.
On the map I’ve also shown the approximate location of the Hands quarry that was described in 1931 by Dr. Morley Wilson of the Geological Survey of Canada. While the Hands quarry is only two miles south of Tackaberry’s current quarry on Highway 7, and both are mapped as March Formation, the rocks at the two quarries are quite different. The map shows that a fault separates two blocks that have been mapped as March formation, with Tackaberry’s quarry falling on the western block and Hands quarry falling on the southeastern block. The rocks at Hands quarry would be considered typical March Formation (or, more accurately, typical of parts of the March Formation). I mentioned in my September 24, 2012 blog posting that the rocks at Tackaberry’s quarry differ from other areas that have been mapped as March Formation. I still hold that view. The rocks at Tackaberry’s quarry are not typical March Formation, and there might only be a veneer of March Formation.
In my September 24, 2012 blog posting I suggested ‘Drummond sequence’ for the block where Tackaberry’s quarry is located and suggested that the rocks appear to be much older than typical March Formation rocks. I also mentioned that Sir William Logan had reported that he had found Climactichnites and Protichnites at a quarry in Lot 6, Concession 3, Drummond Township, which would fall within the Drummond Sequence. However, my subsequent investigations (see my blog postings of January 31, 2013 , February 11, 2013 and May 6, 2013) showed that the Glen quarry is actually on Lot 3, Concession 3, Drummond Township, and falls in Cambrian Potsdam sandstone rather than within the Drummond sequence that has been mapped as Lower Ordovician March Formation. On the below map I plotted the Glen quarry on Lot 3, Concession 3, Drummond Township on property owned by the Glen family at the time Dr. James Wilson found the tracks that Logan named Climactichnites wilsoni, and where I found a small quarry.
Ripple Marks at the Hands Quarry, Lanark County, Ontario
Dr. Morley Wilson is, I believe, the only person to have written a paper devoted to Ripple marks near Perth, Lanark County. In a short paper published in 1931in the Canadian Field-Naturalist he described ripple marks in the March Formation (known in Dr, Morley Wilson’s time as the “Transition Beds”) and included photographs of the ripple marks. The ripple marks occurred in a quarry “on the farm of Mr. H. J. Hands, Lot 10, Concession II, Drummond Township, Lanark County”. Morley Wilson also mentions that “ The quarry lies about 3 miles northeast of Perth and 300 yards north of the second line of Drummond which forms a part of the original stage road from Perth to Ottawa, ...”. The second line of Drummond is more commonly called the Franktown Road and is shown on maps as County Road 10. Jim Hands and his son Trevor both own property on that lot and Concession, and Jim’s property would be familiar to many Lanark residents as Jim and Trevor are well known auctioneers, and Jim has held many an auction on his property.
Morley Wilson mentions that the ripples occur in thin beds on the Hands quarry floor “everywhere throughout the entire extent of the quarry which is over 200 feet long and 100 feet wide and throughout a range of about 14 inches. The total thickness of strata exposed in the quarry face is about 5 feet. This consists of thin bedded sandy dolomitic limestone, in which beds or zones of white limestone up to 1 inch thick are intercalated sparingly near the top but more abundant near the bottom.”
Morley Wilson also mentions that “The sandstone of ... the Transition Beds is ripple marked in many places, the ripples being for the most part of the unsymmetrical type. The greater part of the ripples trend northeast-southwest or east-west and the steeper side of the crests of the ripples are on their south-east or south sides indicating that the current by which they were formed came from the north-west or north.”
The March Formation
D. A. Williams (1991) of the Ontario Geological Survey states that “The March Formation consists of interbedded quartz sandstone, dolomitic quartz sandstone, sandy dolostone, and dolostone.... Shaly partings occur throughout the formation, and glauconitic partings are present in the dolostones and sandy dolostones. ... Quartz sandstones of the March Formation ... are thinly to thickly bedded, fine to coarse grained, and well sorted. The sandstones range in colour from white to light grey, brown, reddish brown, and green; and weather white to light grey and brown to reddish brown. Small brown-weathering spots are common, and are the result of diffusion into the surrounding pore spaces of iron derived from detrital pyrite, magnetite, or ilmenite grains. The quartz grains are subrounded to well rounded. ... Crossbedding, ripple marks, and burrows are common. The dolomitic quartz sandstones and sandy dolostones are light to medium brownish to bluish grey in colour, and weather brownish grey to buff to reddish brown. They are thinly to thickly bedded and contain finely to medium crystalline carbonate and well rounded, fine to coarse grained quartz sand. Some dolomitic sandstone beds are calcareous, and some sandy dolostone beds are calcitic.
...
The March Formation was deposited in a supratidal to subtidal environment. Supratidal to intertidal deposition and hypersalinity are implied by calcite-filled vugs (originally sulphate nodules) and algal lamination in the dolostones. Intertidal deposition is implied by bipolar crossbedded quartz sandstone containing discrete vertical burrows. Subtidal deposition is indicated by highly bioturbated dolomitic quartz sandstone (Bond and Greggs 1973, p.1147-1150). A similar environment was inferred for the Theresa Formation of adjacent New York State by Selleck (1984).”
Williams’ description would cover the rocks of the Hands’ quarry (sandy dolomitic limestone), but is not apt for the majority of rocks of Tackaberry’s quarry as cross-bedding is not common, the burrows are confined to the top beds, there are no calcite-filled vugs, and there is little dolostone in Tackaberry’s quarry. In addition, finding the Ediacaran holdfast Aspidella in the rocks tells against the rocks being Lower Ordovician March Formation.
References and Selected Bibliography
Below I’ve provided a few references to water ripples and wind ripples. If the reader is going to read one reference in addition to Morley Wilson’s paper, it should probably be Kindle (1917). That said, Evans (1942) makes the important point that “The size of wave-formed ripple marks depends on the depth of water and the size of the generating waves. With waves of a given size, the deeper the water the smaller the ripple marks; with a given depth of water, the smaller the waves, the smaller the size of the ripple marks.”

Postscript (March 19th): It has always impressed me that Sir William Logan was able to identify both water ripple marks and wind ripple marks in the Potsdam sandstones at Beauharnois where he found Protichnites tracks, and that he concluded that the creature “which impressed the [Protichnites] tracks at Beauharnois must have been a littoral animal.” See: Logan (1860), where he named Climactichnites Wilsoni; and Logan (1863), The Geology of Canada. It is also worth noting that Logan (1863) provides various measured sections of Potsdam sandstone, including a section from Beauharnois in the vicinity of Henault’s field (1863, pages 105-106), where he describes the beds and indicates where ripple marks, wind marks, Protichnites tracks and Scolithus occur.

Concentric Structures in the Sedimentary Rocks of Lanark County, Ontario that are identical to the Ediacaran Holdfast Aspidella
As part of my blog posting from September 13, 2013 that was entitled ‘A Selection of Fossils from the March Formation in Lanark County, Ontario’ I included a number of photographs of concentric disc shaped fossils from Tackaberry’s quarry a few miles north east of Perth, Ontario in the hopes that someone would study the fossils and provide an accurate identification. That didn’t happen, as my blog posting failed to generate any interest. I’ve decided to try again, with a more intriguing title.
Below I’ve included a number of additional photographs that I took in 2012 of concentric structures in the rocks at Tackaberry’s quarry.
When I first looked at the fossils I did ask a few geologists for their suggestions. One suggested medusae. Another suggested poorly preserved Gastropods. To understand why their suggestions were reasonable, it helps to know that I showed them photographs of poorly preserved specimens from the large blocks surrounding the quarry, before I started looking at specimens revealed by fresh blasting and photographed the specimens shown above and in my September 13, 2013 posting. In addition, there are Gastropods in the March Formation and I’ve found broken specimens of Gastropods in loose blocks at Tackaberry’s quarry.
I now believe that most of the specimens I found were holdfasts, as the specimens are identical to Ediacaran fossils that have been identified as holdfasts. While some might be medusae or badly preserved Gastropods or cross-sections of burrows, these would be in the minority. Most appear to be Aspidella.
My photographs may not be representative of all of the circular structures that I found, as I took photos of the most circular and best preserved specimens that I found. There were many others that were poorly preserved, some that were more elliptical than circular, and some that were not complete circles, that did not get photographed. Admittedly, that does bias the identification, and if I were to go back I would photograph ones with different shapes. (I would also look for fronds.) Interestingly, there were literally hundreds of specimens that did not get photographed.
Since I published the blog posting a tremendous number of authors have written on concentric discoid fossils, and I’ve included a number of those papers below, plus others that I found interesting, and others that included photographs of concentric fossils that are similar to those found in Tackaberry’s quarry. The two Youtube videos -- Cope, 2018 and Burzynski et al. 2017a -- are worth watching.
What is interesting about the specimens that I photographed is that they are all loose specimens resulting from blasting at the quarry. Accordingly, it is as likely that I photographed a bed top as a bed sole. Another interesting point is that while everyone would likely concede that the top beds at the quarry belong to the March Formation and are of Ordovician age, it is not clear how old the lowermost beds are. The uppermost beds are variously coloured siltstones, mudstones and sandstones, and at least two uncomformities are visible. The bottom beds are a reddish sandstone, and at least one Lanark based geologist has suggested that the bottom beds are Potsdam sandstone (which is Cambrian in age). Interestingly, the second time I was at the quarry it was in the company of Dr. Bill Arnott and Dr. Al Donaldson. At that time I picked up a sample of the lowermost sandstone and suggested to Dr. Donaldson that it was Potsdam sandstone. He cautioned me that Precambrian sandstones can be as well preserved as Cambrian sandstones.
I did not find any concentric fossils in the red sandstone.

The fossil record of cnidarian medusae
Palaeoworld, Volume 19, Issues 3–4, December 2010, Pages 212-221
https://doi.org/10.1016/j.palwor.2010.09.014
Below I’ve included a number of additional photographs that I took in 2012 of concentric structures in the rocks at Tackaberry’s quarry.
When I first looked at the fossils I did ask a few geologists for their suggestions. One suggested medusae. Another suggested poorly preserved Gastropods. To understand why their suggestions were reasonable, it helps to know that I showed them photographs of poorly preserved specimens from the large blocks surrounding the quarry, before I started looking at specimens revealed by fresh blasting and photographed the specimens shown above and in my September 13, 2013 posting. In addition, there are Gastropods in the March Formation and I’ve found broken specimens of Gastropods in loose blocks at Tackaberry’s quarry.
I now believe that most of the specimens I found were holdfasts, as the specimens are identical to Ediacaran fossils that have been identified as holdfasts. While some might be medusae or badly preserved Gastropods or cross-sections of burrows, these would be in the minority. Most appear to be Aspidella.
My photographs may not be representative of all of the circular structures that I found, as I took photos of the most circular and best preserved specimens that I found. There were many others that were poorly preserved, some that were more elliptical than circular, and some that were not complete circles, that did not get photographed. Admittedly, that does bias the identification, and if I were to go back I would photograph ones with different shapes. (I would also look for fronds.) Interestingly, there were literally hundreds of specimens that did not get photographed.
Since I published the blog posting a tremendous number of authors have written on concentric discoid fossils, and I’ve included a number of those papers below, plus others that I found interesting, and others that included photographs of concentric fossils that are similar to those found in Tackaberry’s quarry. The two Youtube videos -- Cope, 2018 and Burzynski et al. 2017a -- are worth watching.
What is interesting about the specimens that I photographed is that they are all loose specimens resulting from blasting at the quarry. Accordingly, it is as likely that I photographed a bed top as a bed sole. Another interesting point is that while everyone would likely concede that the top beds at the quarry belong to the March Formation and are of Ordovician age, it is not clear how old the lowermost beds are. The uppermost beds are variously coloured siltstones, mudstones and sandstones, and at least two uncomformities are visible. The bottom beds are a reddish sandstone, and at least one Lanark based geologist has suggested that the bottom beds are Potsdam sandstone (which is Cambrian in age). Interestingly, the second time I was at the quarry it was in the company of Dr. Bill Arnott and Dr. Al Donaldson. At that time I picked up a sample of the lowermost sandstone and suggested to Dr. Donaldson that it was Potsdam sandstone. He cautioned me that Precambrian sandstones can be as well preserved as Cambrian sandstones.
I did not find any concentric fossils in the red sandstone.

The Geological Papers and Maps of Dr. Morley E. Wilson (1881- 1965) of most interest to those in Lanark County
I’ve mentioned Dr. Morley Wilson’s papers and maps a number of times in previous blog postings, without providing any details of his life. This posting will provide a few details of his life, a listing of a number of his papers on economic geology, a selection of his geological papers and maps that would be of most interest to those in Lanark County, as well as a listing of all of his geological papers and maps.
Morley Evans Wilson was born in 1881 in Bright, Ontario, obtained a Bachelor of Arts degree from the University of Toronto in 1907 and his doctorate from Yale University in 1912. He spent his career as a geologist with the Geological Survey of Canada.
Dr. Morley Evans Wilson had strong interests in, and wrote extensively on, economic geology and Precambrian geology, especially mines and mineral deposits in the Canadian Shield. His doctoral thesis was entitled ‘Preliminary memoir on the Abitibi district, Pontiac County, Quebec’, which was published in part as Kewagama Lake Map-Area, Quebec, Memoir 39, Department of Mines, Geological Survey, Ottawa, 1913 and in part as a paper entitled ‘The Cobalt Series; Its Character and Origin’ that was published in the The Journal of Geology, Vol. 21 (1913).. This district was chosen for study because “ little detailed information was available with regard to either the character of the country, its geology, or its economic possibilities. It was further apparent that, owing to its proximity to regions in Ontario where gold had been recently discovered and the easy access afforded by the National Transcontinental railway, the district would soon be actively prospected.” Chapter V of the Memoir is devoted to Economic Geology.
His papers on economic geology include:

Dr. Morley Wilson was awarded the Penrose Medal in 1950 by the Geological Society of America for stratigraphic work that he initiated on the Precambrian, demonstrating that one could use stratigraphic methods to work out structures and sequence in the Precambrian. The Penrose Medal is the top prize awarded by the Geological Society of America, and is awarded only at the discretion of the GSA council, "in recognition of eminent research in pure geology, for outstanding original contributions or achievements that mark a major advance in the science of geology." Interestingly, no award was given in 1929, 1937 or 1943. (Other Canadian recipients of the Penrose Medal were Raymond A. Price in 2012, Paul F. Hoffman in 2011, J. Tuzo Wilson in 1968, N. L. Bowen in 1941, A. P. Coleman in 1936, and Reginald Aldworth Daly in 1935.)
A few other details on his life are available on the internet. He was a Fellow of the Royal Society of Canada (1926). He was on the Board of Examiners from 1929 to 1931 for Frontier College. He was an active member of the Ottawa Field Naturalists Club, serving as a member of council in 1929, as vice-president from 1930-1933 and president in 1934 and 1935. After he retired from the Geological Survey he was a Sessional Lecturer in Geology at Carleton University from 1947-1953. He loved to curl. After Dr. Morley Wilson died his estate endowed geologic scholarships in his name at Carleton University in Ottawa and Queen’s University at Kingston.
Dr. James M. Harrison, a former director of the Geological Survey of Canada, in an unpublished paper entitled ‘Tales of the GSC,’ provides a number of anecdotes on Morley Wilson. Dr. Harrison mentions that “Morley Wilson was a small, spare, sparrow-like man whose religion, vocation, and hobby was geology.” By way of example, he mentions that for September 3 and 10, 1939 Dr. Morley Wilson and Dr. Ambrose had planned meetings and field trips with Ontario and Quebec geologists to look at points of stratigraphic interest near Noranda, Quebec. It happened that September 3rd was the day Britain declared war on Germany while September 10th was the day that Canada declared war. While Morley Wilson wanted to talk geology, no one was listening. Dr. Harrison comments on the September 3rd field trip: “Dr. Wilson who rarely ever took a drink of any sort, got so desperate that he grabbed a bottle of beer around the neck so that it hung down below his hand, and then walked around through the crowd trying to stir up talk on geology without any success whatsoever. I’m sure he felt that the whole day was entirely wasted talking about inconsequential things. ”
Dr. Harrison dictated on tape his reminiscences of various field officers of the Survey, which have transcribed and are available on the Government of Canada’s online GEOSCAN database of papers and maps:
Harrison, James M., dictated on tape 1988, transcribed, edited 1992
Tales of the GSC
https://geoscan.nrcan.gc.ca/text/geoscan/fulltext/GSCHIS_B001docs.pdf
Dr. Harrison provides other anecdotes about Morley Wilson, including mentioning that “Morley was noted for running his party as if it were in civilization....”, that he (Harrison) and Dr. Ambrose were invited “over to dinner one Sunday to Morley Wilson’s field camp which at that time was in some of the buildings of the abandoned McWatter mine near Noranda . ... I don’t remember if we wore ties, but I think we did. ... When the cook rang the bell for dinner, we trooped [in] ... where Morley sat at the head of the table. On his right sat Dr. Ambrose, on his left sat the subchief of Dr. Wilson’s party, ... I sat next to Willis Ambrose, as presumably the most senior of the senior associates of the two parties, and so on down the table [to] the most junior assistant... Grace was said, and Morley carved the meat, and we carried on exactly as if we were dining in the main dining room of the Chateau Laurier.”
A paper that I have not been able to read, as it is not available online, and which I expect provides details of Dr. Morley Wilson’s career, is Dr. Alcock’s obituary notice for Dr. Morley Wilson:
Alcock, Frederick J., 1966
Morley Evans Wilson. 1881-1965: Royal Soc. Canada Minutes Proc. 1966, 4th ser., v. 4, p. 123-124. portrait, 1966.

At the end of this blog posting I’ve provided what should be a fairly complete list of Dr. Morley Evans Wilson’s geologic papers and maps. Most were found in various editions of the Bibliography of North American Geology. I supplemented those papers and maps with those on the Government of Canada’s online GEOSCAN database, and with others found by searching on the internet. From that list I’ve selected the papers and maps that I believe to be of most interest to those in Lanark County. These are my selections.

Morley Evans Wilson was born in 1881 in Bright, Ontario, obtained a Bachelor of Arts degree from the University of Toronto in 1907 and his doctorate from Yale University in 1912. He spent his career as a geologist with the Geological Survey of Canada.
Dr. Morley Evans Wilson had strong interests in, and wrote extensively on, economic geology and Precambrian geology, especially mines and mineral deposits in the Canadian Shield. His doctoral thesis was entitled ‘Preliminary memoir on the Abitibi district, Pontiac County, Quebec’, which was published in part as Kewagama Lake Map-Area, Quebec, Memoir 39, Department of Mines, Geological Survey, Ottawa, 1913 and in part as a paper entitled ‘The Cobalt Series; Its Character and Origin’ that was published in the The Journal of Geology, Vol. 21 (1913).. This district was chosen for study because “ little detailed information was available with regard to either the character of the country, its geology, or its economic possibilities. It was further apparent that, owing to its proximity to regions in Ontario where gold had been recently discovered and the easy access afforded by the National Transcontinental railway, the district would soon be actively prospected.” Chapter V of the Memoir is devoted to Economic Geology.
His papers on economic geology include:

Dr. Morley Wilson was awarded the Penrose Medal in 1950 by the Geological Society of America for stratigraphic work that he initiated on the Precambrian, demonstrating that one could use stratigraphic methods to work out structures and sequence in the Precambrian. The Penrose Medal is the top prize awarded by the Geological Society of America, and is awarded only at the discretion of the GSA council, "in recognition of eminent research in pure geology, for outstanding original contributions or achievements that mark a major advance in the science of geology." Interestingly, no award was given in 1929, 1937 or 1943. (Other Canadian recipients of the Penrose Medal were Raymond A. Price in 2012, Paul F. Hoffman in 2011, J. Tuzo Wilson in 1968, N. L. Bowen in 1941, A. P. Coleman in 1936, and Reginald Aldworth Daly in 1935.)
A few other details on his life are available on the internet. He was a Fellow of the Royal Society of Canada (1926). He was on the Board of Examiners from 1929 to 1931 for Frontier College. He was an active member of the Ottawa Field Naturalists Club, serving as a member of council in 1929, as vice-president from 1930-1933 and president in 1934 and 1935. After he retired from the Geological Survey he was a Sessional Lecturer in Geology at Carleton University from 1947-1953. He loved to curl. After Dr. Morley Wilson died his estate endowed geologic scholarships in his name at Carleton University in Ottawa and Queen’s University at Kingston.
Dr. James M. Harrison, a former director of the Geological Survey of Canada, in an unpublished paper entitled ‘Tales of the GSC,’ provides a number of anecdotes on Morley Wilson. Dr. Harrison mentions that “Morley Wilson was a small, spare, sparrow-like man whose religion, vocation, and hobby was geology.” By way of example, he mentions that for September 3 and 10, 1939 Dr. Morley Wilson and Dr. Ambrose had planned meetings and field trips with Ontario and Quebec geologists to look at points of stratigraphic interest near Noranda, Quebec. It happened that September 3rd was the day Britain declared war on Germany while September 10th was the day that Canada declared war. While Morley Wilson wanted to talk geology, no one was listening. Dr. Harrison comments on the September 3rd field trip: “Dr. Wilson who rarely ever took a drink of any sort, got so desperate that he grabbed a bottle of beer around the neck so that it hung down below his hand, and then walked around through the crowd trying to stir up talk on geology without any success whatsoever. I’m sure he felt that the whole day was entirely wasted talking about inconsequential things. ”
Dr. Harrison dictated on tape his reminiscences of various field officers of the Survey, which have transcribed and are available on the Government of Canada’s online GEOSCAN database of papers and maps:
Harrison, James M., dictated on tape 1988, transcribed, edited 1992
Tales of the GSC
https://geoscan.nrcan.gc.ca/text/geoscan/fulltext/GSCHIS_B001docs.pdf
Dr. Harrison provides other anecdotes about Morley Wilson, including mentioning that “Morley was noted for running his party as if it were in civilization....”, that he (Harrison) and Dr. Ambrose were invited “over to dinner one Sunday to Morley Wilson’s field camp which at that time was in some of the buildings of the abandoned McWatter mine near Noranda . ... I don’t remember if we wore ties, but I think we did. ... When the cook rang the bell for dinner, we trooped [in] ... where Morley sat at the head of the table. On his right sat Dr. Ambrose, on his left sat the subchief of Dr. Wilson’s party, ... I sat next to Willis Ambrose, as presumably the most senior of the senior associates of the two parties, and so on down the table [to] the most junior assistant... Grace was said, and Morley carved the meat, and we carried on exactly as if we were dining in the main dining room of the Chateau Laurier.”
A paper that I have not been able to read, as it is not available online, and which I expect provides details of Dr. Morley Wilson’s career, is Dr. Alcock’s obituary notice for Dr. Morley Wilson:

At the end of this blog posting I’ve provided what should be a fairly complete list of Dr. Morley Evans Wilson’s geologic papers and maps. Most were found in various editions of the Bibliography of North American Geology. I supplemented those papers and maps with those on the Government of Canada’s online GEOSCAN database, and with others found by searching on the internet. From that list I’ve selected the papers and maps that I believe to be of most interest to those in Lanark County. These are my selections.
