Godrel Posted September 6, 2019 Share Posted September 6, 2019 (edited) I found this in the sangamon river by Decatur Illinois in Macon county. It was found in what looked like a glacial depost in the river. I don't think it is a brachiopod as the shape doesn't quite look right. I think it might be the tail of trilobite.

Fossildude19 Posted September 6, 2019 Share Posted September 6, 2019 Hello. Nice find. This is the pygidium of a Dalmantid trilobite. Not sure of genus or species, but @piranha should be able to figure this out.
