Rockwood Posted August 3 Share Posted August 3 They're brachiopods, for openers. 1 Link to post Share on other sites
Fossildude19 Posted August 3 Share Posted August 3 They look like internal molds of Spiriferid brachiopods. Pretty common in that area. 3 1 Link to post Share on other sites
Rockwood Posted August 3 Share Posted August 3 Internal molds I agree with, but the shape doesn't suggest spiriferid to me. Link to post Share on other sites

Harry Pristis Posted August 3 Share Posted August 3 I see internal casts and partial external molds . . . no internal molds. 1 1 1 Link to post Share on other sites
Fossildude19 Posted August 3 Share Posted August 3 Yes. Internal casts. Steinkerns, if you like. Link to post Share on other sites
BobCow Posted August 3 Author Share Posted August 3 Thank you for all the responses. We do find plenty of the Spiriferid brachiopods, both internal and external casts. The round objects were the fossils that we have not seen before..are they connected to the Spiriferid brachiopods? Link to post Share on other sites
Rockwood Posted August 3 Share Posted August 3 @Tidgy's Dad Might have an opinion on those internal molds. 1 Link to post Share on other sites
Tidgy's Dad Posted August 3 Share Posted August 3 Bit difficult to be certain, but I think spiriferid internal casts are the most likely id. 1 Link to post Share on other sites
Rockwood Posted August 3 Share Posted August 3 @BobCow The distinction between an internal mold and a cast is sort of an ongoing friendly dispute. For me wood burning stoves and engine blocks are cast. Fossils are presented as molds of the designated surface. Link to post Share on other sites

What do you mean by round objects? If you mean these: These are the "beak" sections of the brachiopods. Source of image Link to post Share on other sites

BobCow Posted August 4 Author Share Posted August 4 Thank you for all your input. Find plenty of the brachiopods in the creek and on the beach at our cottage but had not seen the 'beak' in this form before. 1 Link to post Share on other sites
