Cameron613 Posted August 22, 2018 Share Posted August 22, 2018 Here are 3 crustacean fossils I found when I was younger and held onto them because I thought they were the coolest things ever. They were all found in the Ottawa area. There is also one other fossil which I’m not positive what it is. It sort of looks like a tony bone or a bit of coral. Helping to ID these would be so cool if possible! Link to comment Share on other sites More sharing options...

Cameron613 Posted August 22, 2018 Author Share Posted August 22, 2018 Here is the last one that is tiny and I’m not sure what it is exactly. Link to comment Share on other sites More sharing options...
izak_ Posted August 22, 2018 Share Posted August 22, 2018 Nice finds, but they aren't crustaceans #1 is a partial trilobite pygidium #2 is a crinoid hashplate (stem segments) #3 is the impression of a brachiopod People more familiar with you area may be able to narrow down the ID 3 Link to comment Share on other sites More sharing options...

Thanks for the help. In the first one beside (left) the trilobite, there is another small fossil fragment. Is that part of the same trilobite or is it a different specimen?

Looks like a segment of a small crinoid stem. The ligaments in them often held long enough for the ossicles to remain articulated. 24 minutes ago, belemniten said: Where do you see a pygidium there?

The ridges toward the bottom of the pic. do not seem quite radial enough to be crenelations of one to me. 1 Link to comment Share on other sites More sharing options...

Helping to ID these would be so cool if possible! This would be the pygidium of the trilobite Pseudogygites latimarginatus, which are fairly numerous as moults in the Ottawa area.
