Hello! I was here a few years ago asking for ID, and I'm back again. I scour the Humber river in Toronto for water insects and rocks, usually, and I found what I think are some fossils! If anyone can help me identify them, I'd be very grateful. I have some pictures below. The 'fossil', if it is a fossil, is just slightly under a centimeter across. (As a bit of an aside, I'm an avid fan of rocks but I can't usually figure out what they are, other than nice to look at. Is this an appropriate place for potentially IDing those, as well? Or should I find a rock forum in particular?) 1. This is the only one I think I know! I'm assuming those are crinoid bits in there. The rock itself is a little over two inches across. This is the front, And this is the back. 2. All I know is this seems shellish. Front and back, below. About an inch, maybe a little more. 3. This one seems similar to the one above, but I've got an eye for bugs, not for fossils. An inch across, if not a little more. 4. No idea where to start with this. The upper left corner is what caught my eye. The macro shot is a bit blurry. My apologies! The 'fossil', if it is one, is about a centimeter wide, slightly less.

While going through mostly Amherstburg/Lucas Fm material with some Dundee Fm today, I encountered this fairly large cephalon (~5 cm wide). Odontocephalus (n.sp?) pygidia have appeared in this material, along with Pseudodechenella and Crassiproetus (and just one tiny "Mystrocephala" pygidium). Overall, though, it is miserable, chalk-cherty, bituminous, generally low sedimentation material. It seems a match for Trypaulites, but it seems a bit on the large side (and the exaggerated anterior "prow" gives me pause). Apart from age of the material, I can likely rule out Anchiopsis given the absence of the occipital spine. If it is Trypaulites (making my first cephalon find of this genus), I am not entirely satisfied with making that call more certain on the basis of either images in Ludvigsen or Lespérance. I could be overthinking what could simply be an artifact of preservation or a natural in-genus morphological variation, but always best to get a second opinion.

A recent visit to one of my special Dundee Fm locations yielded the usual assortment of fragments of Coronura aspectans, Pseudodechenella sp. Odontocephalus (n.sp.?), Trypaulites sp., and Crassiproetus sp. This one fragment was found in the talus of my splits (so I could not locate the impression, and it sits on the natural edge of the rock). The material is a near-shore fissile facies of the Dundee Fm (SW Ontario). Comparing against other usual fragments has not made for a satisfactory enough match for me. I'm including a closeup grey-scaled image of the fragment, and a regular photo (which includes a Coronura aspectans pleural segment above the fragment). The pygidial "margin" appears quite a bit larger and effaced. For scale reference, the pygidial axis measures 1.1 cm in length.

I know crinoid "forests" are a dime a dozen, but still its nice to find one so packed . . . And some bryozoan pieces, my first that I can identify with a bit of confidence . . . but please correct if I'm mistaken. Cheers!

These bits are on the same piece of rock, kindly sent to me by the marvelous @Monica. They are from the Etobicoke Creek, Toronto, Ontario, Canada and are Georgian Bay Formation which is Late Ordovician in age. I think they are likely bryozoa, but stromatoporoid might be possible for the first one and algae for the second. They are found in a piece of rock that also contains Paupospira (was Lophospira) gastropods, crinoid stems and individual columnals, Cornulites flexuosus and Flexicalymene granulosa. The first one doesn't seem to have much depth to it. 1 to 2 mm at most. The second one is a stick ! Another stick : And what are the spiky toothy things?

I found this fossil in the Georgian bay formation in the GTA in southern Ontario. I have no idea what the area highlighted in blue is (first picture). It looks like a slug or some type of annelid. My only guess is some type of Machaeridian, but I doubt it's that as well. Any ideas? It measures around 9 cm tip to tip, Thanks

Crystalline... Sponge? (Little Current, Manitoulin Island, Ontario)
CabinTom posted a topic in Fossil ID
Found along the shore of the North Channel at Little Current, Ontario. Large, bumpy nodule which seems to be completely formed of (calcite?) crystals all the way through (I'm surprised by the multiple colours, but maybe that's normal?). I'm assuming it's a sponge, though wondering if someone could give a more specific ID or perhaps explain the crystallization seen here.

Found in a roadside cut on Goat Island, just north of Manitoulin Island's swing bridge. A layer of hexagonal "scales" overlaying a branched structure. What is this? I have no idea what I'm looking at! Also the top corner has a small ribbed structure which seems to be separate from the rest. If someone has an ID for this as well, that'd be amazing!

Found on Manitoulin Island. I believe at Kagawong... but unfortunately, it's been a while and I didn't make any notes at the time.

Found on the shore of the North Channel at Little Current, Manitoulin Island, Ontario. The side of the piece features a transverse view of a Crinoid. Can this be ID'd more specifically? Above is some sort of shell. Can this be ID'd? There are various other small fossils, though I don't know if those are identifiable.

Trilobite? (Little Current, Manitoulin Island, Ontario, Canada)
CabinTom posted a topic in Fossil ID
I found this along the shore of the North Channel at Little Current, Manitoulin Island, Ontario. I understand the small dark traces are Graptolites. Would anyone have any info on what I assume is a Trilobite?

Hi guys I decided to rescue and acquire a new unlabelled specimen. It appears to be a rugose solitary coral that can possibly come from the Devonian of south western Ontario. Can anyone give me any leads on the species level??

As promised here is another of the specimens that I prepared that will be included in the new "Dawn of Life" gallery at the ROM. Not sure it belongs in the Preparation topic as I only have the single picture. Moderator feel free to move. Those that know me realize that I hate taking pictures. There are occasions when you get to work on a specimen that you absolutely do not want to return at the end of preparation. That was certainly the case with this one. Of all the specimens I have ever prepared for someone else, this plate is probably the one that I most wanted to keep for my own collection. This is natures art at its finest. This is in my opinion a stunning associated pair of trilobites a large Gabriceraurus hirsuitus (synomynous with G. dentatus) associated with a much smaller Ceraurus globulobatus. Hopefully a long awaited paper will be coming clarifying the naming of all these cheirids. This specimen is the plesiotype for the species and is catalogued as ROM specimen 46105. This specimen was selected to be featured in the new permanent "Dawn of Life" gallery at The ROM opening late 2021 (Covid permitting). Thank you Dr. JB Caron for permission to share. This specimen was originally described in a paper by William Hessin back in 1988 and was collected Bill at Brechin Quarry in the 1980's Truth in advertising. I was asked to do a repreparation and minor repairs to the specimen prior to public display in the gallery. Some preparation had been performed back in the 80's. I spent approximately 20 hours on this specimen. This work was done probono and was my pleasure and privilege to have been involved. It was done exclusively under an Olympus SZ30 stereo microscope using a COMCO MB1000 air abrasion unit using only sub 40 micron baking soda. All work was performed with .015 and .010 nozzles at under 10 PSI. (Hence why it took 20 hours). A small amount of scribe work was performed using a Pferd MST31 with fine styl;us and a Paleotools microjack-2. Some Minor repairs were completed using Bob Smith Industries Instacure super thin cyanoacrylate and Milliput super fine white 2 part putty. Unfortunately I only took a single picture . So here it is for your viewing pleasure. Definitely one of my favorites. Yes they are different species but as I was prepping this one I kept thinking of it as "Madonna and Child" So here here is what I refer to as "Madonna and Child" Please feel free to ask questions or you can PM me directly

Today Deb and I made the two hour drive up to just outside the town of Formosa, Ontario, to have a look at the Formosa reef limestone, which is part of the Amherstburg Formation. This road cut is the type locality for this material, and it was humbling to be at the exact same location that researchers of yesteryear such as Ludvigsen and Fagerstrom derived their material that formed the basis of their published work on it. Here are some shots of the road cut. Hardly does it justice. This represents a single, massive biohermal knoll. I've wanted to visit this site for a while now, having read two key papers on it. Most of the non-coral fossils are found on the south edge of the cut, as it is assumed that this was the windward side of the knoll that captured much of the debris swept in by the currents.

Hi guys so today I came across a new shop that popped up in downtown Hamilton, Ontario. Anyway long story short I bought what appears to be Silurian coral fossil that originated somewhere on the Niagara Escarpment in Ontario or the State of New York. This fossil came from a peculiar museum that liquidated its collections in Niagara of Ontario and closed but the fossil didnt come with a label. Can anyone help me pin down what it is? I have never encountered a fossil like this on the Niagara Escarpment of Hamilton, Ontario. Also this was being sold along with other/what appears to be Silurian corals from the local area of the Niagara region of Ontario/New York.

Finally I can share an incredible piece with you all!!!!!!!! I have been very fortunate to be able to do invertebrate fossil preparation for The Royal Ontario Museum (The ROM). I have recently been given permission to share pictures of some of the work that I have done for them. Thank you Dr. J.B. Caron. In the coming weeks I will share some pictures of other pieces I did for them. In total I prepared about 12 pieces for them out of their collection and I donated 7 pieces for the new gallery. In case you are not already aware they will be opening a major new fossil gallery "The Dawn of Life" later this year. Here is a major piece that I did for them last year. The piece is quite stunning in person , my photography does it no justice. You will be able to see it in person in the new gallery. There are over 60 Leviceraurus mammilloides on the plate. As well as a few other species of crinoid and trilobite. To spare you all the waiting here is the finished piece The piece was prepared over a 12 month period and required around 200 hours to prepare. It was prepared under a Olympus zoom microscope using the following air scribes (CP9361, ARO, Pferd MST-31, Paleotools Microjac 2) The air abrasion was performed with a Comco MB1000 using baking soda and dolomite in the 40 micron range and mostly 20 to 30 PSI. Since this was a piece of scientific importance (there may be a new species on here and it potentially shows some sexual dimorphism ) all associations were left on the plate. If a brachiopod was covering a trilobite it was not removed. Partial trilos were not removed to exposed complete ones below it. Dr. Caron was quite specific in what he wanted in the way the specimen was prepared. There are probably more trilos that have not been exposed and these may be discovered in the future by Xray. At 200 hours I quit searching for more as the plate had nice aesthetics and the museum needed it to do professional photography and measuring for the display. This picture is as it was found in the field back in 2019 by David A. who is a member here on the fossil forum. The fossil was found in an Ordovician quarry (St. Mary's Cement) that allows a very limited number of qualified collectors in a few times per year. The slab as found required 4 people to bring it down the side of a very large blast pile using a blanket. It was estimated that the slab weighed about 300 pounds. Here I am u The 2nd and 3rd pictures are me cutting and thinning the slab using a checkerboard technique done with a diamond rock saw. This got the piece to a transport weight of about 60 pounds. The rest of the pictures are a sequence leading up to the finished piece which weighs about 50 pounds and was the first picture shown in this post. If you have any questions please feel free to ask or send me a private message if you prefer. The piece in my basement before any preparation. Not so pretty at this point in its life.... The piece at 1 hour The final shot here was with about 20 hours to go

A year ago I was able to hook up with my field comrade for some time in the Lagerstatte of the Silurian Eramosa in Ontario (northern section). This was a place where land and sea scorpions were found by the ROM. We did not find any. We obtained permission to enter quarries on account of connections and complying by safety rules. They do not let casual collectors in, so it was on account of those connections that we gained access. These quarries specialize in flagstone. Much of it is blank. Our focus was on the rubbly upper portion of the Silurian. As stated, fossils are very sparse in this material. Gastropods are the dominant fauna in some horizons, but even then very sporadic. These are largely lagoonal facies.
