fjoewreio Posted June 1, 2022 Share Posted June 1, 2022 Hello all, It's been a long time since I've been on here, but my interest in collecting Ontario trilobites has been renewed over the past few years. One of my goals has been to find a trilobite piece on a job site. I was near Port Hope last week and went to check out a fill pile on my break when I flipped over a rock and found this little guy. Since it was in a fill pile I have no idea what formation it's from, or its age, and so I'm having a hard time id'ing this specimen. I would appreciate any help. Thanks. Location: Fill pile near Port Hope, Ontario Age:Unknown Formation: Unknown Size: approx 1cm x 1cm 3 Link to comment Share on other sites More sharing options...
Misha Posted June 2, 2022 Share Posted June 2, 2022 @Kane is very familiar with the trilobites of ON, maybe he might know? @piranha could probably help too 1 Link to comment Share on other sites More sharing options...

fjoewreio Posted June 2, 2022 Author Share Posted June 2, 2022 @piranha Thank you very much! A new species for me. My own guess was Crassiproetus crassimarginatus but it didn't feel right. I'll have to go over that source document and learn a bit more. Link to comment Share on other sites More sharing options...
