    Summer Hunts of 2023

    I have had multiple trips this summer to my favourite localities in Hamilton, Ontario and Toronto. I dont think the winter of this season was severe to render a great deal of erosion since I couldnt pick out a lot of material surface wise. My first trip is at the Niagara Escarpment of Hamilton in which I visit many formations of the Cataract and Clinton Groups. Always keep an eye out on your overhead! These rocks of the Whirlpool sandstone (Cataract Group) on top of the Queenston formation can drop on any unsuspecting person! Below are some partial pentamerid brach

    Pentameroides subrectus

    From the album: Hamilton, Ontario Fossils

    Pentameroides subrectus (Hall and Clarke, 1892). One of the valves of this mid-Silurian brachiopod. Found at a creek along the Niagara Escarpment in Hamilton, Ontario. Reynales formation, Clinton Group.

    From the album: Hamilton, Ontario Fossils

    Pentameroides subrectus (Hall and Clarke, 1892). Found at the Niagara Escarpment on a creek in Hamilton, Ontario. Reynales formation, Clinton Group. Mid-Silurian. This brachiopod steinkern has specks of pyrite on it.

    Trilobite Pygidiums from Tobermory?

    I found a couple of these while staying in the immediate Tobermory area a few weeks ago. To my untrained eye they appear to be trilobite pygidiums. Is there any way of possibly determining their identity? I took these photos around the time of discovery, and I can take higher quality ones if needed. Both specimens are 1.8cm and 1.1 cm in length.
  15. Crowdsourcing / help request! I'm putting together a review article for the fossil collector community on the Devonian rocks of the American midcontinent, which I've defined as the gray area on the map below plus southwest Ontario. I'm hoping to include a section in which I highlight the midcontinent fossils of greatest renown for each of a number of taxa (list below). (I purposely leave "renown" as a somewhat squishy quality open to multiple interpretations.) I would appreciate (1) your nominations of any midcontinent Devonian fossils of great renown that I have f

    Fossil ID - Grimsby Beach, Ontario

    Hi, went to Grimsby Beach and was looking at the rocks. Found some that seemed interesting to me, and thought maybe they could be fossils. Please let me know as I barely have any experience with fossil hunting.
  17. A few finds from this weekend. Fortunate enough to have a cottage on Lake Erie, fairly close to Rock Point Provincial Park which is known for it's exposed fossils of a 350 million year old coral reef. About half were found on the beach itself and the other half in the crushed gravel part of the driveway. I'd imagine the beach will keep yielding new finds after every storm, here is hoping for it anyway.
  18. I'm pretty new to fossil hunting, I found this in some landscaping outside my work. I've done some research myself, i live in Ontario which is mostly Devonian era fossils, and I've read coral is pretty common. Could be entirely wrong and just hoping for some clarification!
  19. Just now getting through some camera rolls and specimen photo-taking of a two week trip in May. I covered about 2000 miles across Ontario and Quebec, and this is a sample of what I saw and/or collected. I won't be mentioning any specific sites, so I'll just number them. Site 1: Pleurocystites Pleurocystites close-up A crappy Calyptaulax Possibly a Flexicalymene senaria, disarticulated impression. Leaverite. A busted, incomplete cheirurid. Leaverite. Large Isotelus gigas cheek. (Also leaverite )

    Unknown shape in chert, possibly Ceraurinus

    Here's something I found a few months ago. There are lots of bits of brachiopods which seem to have been preserved in their original perfect shape instead of the casts I usually find. It's what's on top of them that interests me. It looks like it could be a trilobite cephalon, if that's the case then the closest match I could find was Ceraurinus sp. I'm pretty sure I saw something to do with a crinoid that looked similar though I haven't been able to find it again. Any other ideas?

    Ordovician sponges?

    While splitting upper Ordovician shales in Ontario, I encountered these and reasoned it was possible these were sponges (owing to the presence of what appear to be spicules). I have encountered sponges in the upper Ordovician limestones, but not in the shales. The solo specimen measures about 1 cm. The cluster piece contain specimens slightly smaller than that. Firstly, I just wanted to rule out these as simply artifacts of mineralization. If they are sponges, I was curious if anyone had a bead on their genus as sponges are well outside my wheelhouse.
  22. Taxonomy from Fossilworks.com. Synonym Ectenocrinus canadensis Billings 1857. Ectenocrinus simplex can be well recognized by its distinctive trimeric columnals. References: Hall, J. (1847).

  23. Hey everyone, I wanted to show this fossil I found back in November as I think it's pretty cool. On my first trip that involved splitting shale, I found this Triarthrus cephalon, which is cool on it's own but it was only later that I looked back to it and realized the particular shape that resides on top of and below the cephalon. This trilobite appears to have been buried with the shell of a nautiloid! Please excuse if it's hard to see, the first few pictures were really difficult to get and my phone isn't the best at taking close up shots as it is. The 1st and second pictures repre
  24. I found this specimen in 2020 and donated it to the Royal Ontario Museum later that year. A paper is to be published very soon formally describing it! It's a roughly 7cm wide mimetasterid marrellomorph - the only marrellomorph know from the Ordovician of Canada, and one of a handful of such arthropods recorded worldwide. I found my very first trilobite in 2014. The members of this forum helped my ID it, learn more about the stratigraphy of my area and what tools to use to find more. Thanks to that base of knowledge,, the last 7 years have seen paleontology become an increas
