Barasingha Posted January 16, 2017 Share Posted January 16, 2017 Sorry about the poor quality first picture but I am not able to currently take another pic. This was found in a Miocene area. Can you tell me if this is an urchin or something else? Thanks. Link to comment Share on other sites More sharing options...
FossilDAWG Posted January 16, 2017 Share Posted January 16, 2017 That is not an urchin, it lacks the plate structure, the ambulacra, and any sign of a mouth or anus. I think it is a disc that goes between vertebrae. Such discs, from cetaceans, are not uncommon in some marine formations such as the Miocene formations around the Chesapeake Bay area.

Fossildude19 Posted January 16, 2017 Share Posted January 16, 2017 I agree with Don - vertebral epiphysis.

abyssunder Posted January 16, 2017 Share Posted January 16, 2017 Epiphysis for sure, I agree with the others. Here is for example a vertebral epiphysis from a whale to compare with: Also, nice epiphysis here, showing both sides: " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
