Fossils found in Berriasian marl, Chartreuse, France

[McKlakett]

Hi everyone, 

I found this two fossils in Berriasian marl, in the Chartreuse mountains in France. 

I'm a bit struggling to identify them, I would be happy if somebody in here could help me. 

Thanks a lot for your help !

Maybe the bit of adhering matrix is confusing my eyes, but the second one looks like a crab claw.  Are they possible out of that formation as I am not familiar with it at all?

To be a little more specific, they are some sort of ghost shrimp (callianassid).  There are a lot of genera, and obviously more species in this group.  It would be a challenge to identify your fossils more precisely from photos.

I agree with Callianassid

Thanks for your help ! 

I couldn't find any pictures of callianassid fossils online, where this kind of texture/pattern was visible. 

Have you already seen this kind of pattern/texture on a callianassid fossil ? If yes could you share those picture with me ? 

Thanks again for your help !
