Alison.K.Monahan Posted November 15, 2018 Share Posted November 15, 2018 Here's my issue, I work in a science museum and our former director wasn't good at curating. He often knew what things were on sight, but he didn't write down much for us. I have a whole box of unknown fossils. Since we have several specimens of this fossil type, they were likely collected in South or North Carolina. We do have fossils and specimens from all over the world though, so it's not a guarantee. So I don't know the location, I don't know anything about the geology, and I haven't been able to find similar fossils online visually. I have many pictures, struggling with the file size restraints. I will post more pictures in the reply. Please ask for any details I may have. Link to comment Share on other sites More sharing options...

Paciphacops Posted November 15, 2018 Share Posted November 15, 2018 These appear to be bivalve steinkerns, which is the internal sediment that hardened inside the bivalve, which then weathered away, leaving an internal cast. 3 "Don't force it, just use a bigger hammer" Link to comment Share on other sites More sharing options...
jpc Posted November 15, 2018 Share Posted November 15, 2018 Internal mold of a clam... TX folks should be able to say more. They are common in TX Cretaceous, but the preservation is different. Link to comment Share on other sites More sharing options...

sixgill pete Posted November 15, 2018 Share Posted November 15, 2018 These appear to be these steinkerns of Cucullaea sp. a, a false Ark Clam.

Fossildude19 Posted November 15, 2018 Share Posted November 15, 2018 They are sometimes colloquially called "deer heart clams" or "turtle heads" I agree with Don - Cucullaea sp.
