fifbrindacier Posted August 13, 2016 Share Posted August 13, 2016 (edited) Hi, welcome from France. Could you tell us where do they come from, what is their geological age if you know it, what are their size and what kind of stuff you can find nearby ? Really, that would help very much.

CraigHyatt Posted August 13, 2016 Share Posted August 13, 2016 Welcome to the forum. Where did you find these (geographical location or geological layer)? What are the dimensions of each specimen? Can you post photos of each specimen from several different angles? This will greatly improve your chances of getting a correct identification. Info: Craig Hyatt, retired software/electrical engineer Experience: Beginner, fossil hunting less than a year Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert Formation: Escondido, Marine, Upper Cretaceous Materials: Sandstone, Mudstone, Shale, Chert, Chalk Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus Reference: http://txfossils.com/Txfossils.html Link to comment Share on other sites More sharing options...
abyssunder Posted August 13, 2016 Share Posted August 13, 2016 Welcome to TFF ! Most of them look like internal molds (steinkerns) of bivalves, the spiralling ones are probably from gastropods, but not knowing the above requested data is just a guess.

abyssunder Posted August 14, 2016 Share Posted August 14, 2016 (edited) With the new data, I think I was in the good direction. Take a look at here, all toghather in Google search. https://www.google.ro/search?q=intenal+molds+of+bivalves&biw=1360&bih=612&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiL-tyUyr_OAhWDtxQKHdkgAHEQ_AUIBigB&gws_rd=cr&ei=zLavV8aeNsLjU9H7nMgJ#tbm=isch&q=internal+molds+of+bivalvesThe last one is a fragment of an internal mold of a bivalve in a view of the valves when they once were closed together (not a rudist upper valve).

fifbrindacier Posted August 14, 2016 Share Posted August 14, 2016 Abyssunder is a mine. You want further information on bivalves ? Ask Abyssunder.
