Alexthefossilfinder Posted February 16, 2023 Share Posted February 16, 2023 I was examining a rock with some crinoids and bryozoans I found in my garage a couple months back, and I was able to find this very small trilobite. It looks to me from my research to be a Triarthrus, but I'm still a little unsure on the species. I'm leaning towards eatoni, though I'm not 100% sure. Apologies that the photos aren't the best, but the thing is really small and I don't have the best macro camera. One more note is that I'm aware Triarthrus eatoni isn't found in my area, but I don't know exactly where this rock came from. If I can find the species hopefully I'll be able to get that information.

Kane Posted February 16, 2023 Share Posted February 16, 2023 I very much doubt it. The photo is not all that helpful, but Triarthrus in Ontario appear in shales, not limestone. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 16, 2023 Share Posted February 16, 2023 I'm not convinced this is a trilobite. Better pictures would help. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Northern Sharks Posted February 16, 2023 Share Posted February 16, 2023 To add to Kane's comment, Triarthrus eatoni are found in Ontario not too far from you -Whitby and east. Triarthrus rougensis are even closer. There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...

I was able to use a magnifier at the ROM and get these. Still looks like a trilobite to me, but it kind of resembles the arms of a crinoid too.

FossilDAWG Posted March 24, 2023 Share Posted March 24, 2023 Possibly a fragment of a conularid. Definitely not a trilobite. Don 3 Link to comment Share on other sites More sharing options...
doushantuo Posted March 24, 2023 Share Posted March 24, 2023 Think I'm agreeing with Don here on his assessment. Link to comment Share on other sites More sharing options...

Don I could see that, and likely a segment akin to what I've enclosed in the rectangle here, rotated 90 degrees. This image from Hessin's book is Conularia trentonensis, and seems to me to be the most likely match. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
