caterpillar Posted February 20, 2015 Share Posted February 20, 2015 (edited) Hello all Have you ever seen this kind of material? Found in marine oligocene and miocene of southwest France It's 3 or 5 mm large? This is not Eotrigonodon teeth and not Rhyncholites Thanks for your help Edited February 20, 2015 by caterpillar http://www.paleotheque.fr Link to comment Share on other sites More sharing options...

Al Dente Posted February 20, 2015 Share Posted February 20, 2015 I think michele 1937 is saying these are the back end of a squid. More specifically I think they are the little prong found on the end of a coleoid cephalopod. Here is a drawing of two Oligocene ones from "Two new genera of Coleoidea from the Chickasawhay Limestone (Oliogocene) of Alabama" by Ciampaglio and Weaver 2008. 2 Link to comment Share on other sites More sharing options...

Did you ever get a better ID for this? Back in 2015 I said it matched coleoid prongs based on the Caimpaglio and Weaver 2008 paper. Since then, a 2017 paper came out challenging their identification. It looks like these are shrimp claw tips. Here is the paper reference and an illustration from the paper. I've found similar ones in modern Florida Bay sediments. 1 Link to comment Share on other sites More sharing options...
caterpillar Posted January 10, 2021 Author Share Posted January 10, 2021 No, I did not find a good identification. Why not shrimp claws but no shrimp remains were found in association http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
