French Marine Fossil

[caterpillar]

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

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.

I agree; we have had discussions about these here over the years.

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.

No, I did not find a good identification. Why not shrimp claws but no shrimp remains were found in association
