New Members LakeErie_Fish_Girl Posted June 26 New Members Share Posted June 26 I found this rock in a creek right next to Lake Erie outside of Cleveland, OH. It looks like a fish fin? (This is the first potential fossil I've found naturally, so I'm unsure.) The rock itself is either sandstone or limestone. Any help identifying it would be greatly appreciated!

Rockwood Posted June 26 Share Posted June 26 It's hard to be certain, but I think this is a rugose coral. Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 26 Share Posted June 26 I agree, a cross section through a rugose coral.
