Hey all. I'm not too familiar with fossils outside of nautiloids and corals which are really common here in Ontario. This is the first time I've ever found something different.
Anyone know what it could be? It was found in a dried creek runoff near a shale cliff in the Toronto area. The rock was pretty different from others nearby if that matters, it was powdery and soft compared to the brittle shale all around. I think I might see some early-mid paleozoic fossils on the other side of the rock, though they are very weathered so it's hard to tell.
About 10cm from left to right, canadian quarter for scale. Any help would be appreciated, thanks!
