Crab Claw Switzerland?

[RomainH_Swiss]

Hello, 

Went fossil hunting in a famous Swiss Jurassic Location, the quarry of Liesberg. 

While cracking some rocks found what seems to be a crab claw. 

Can anyone help me identifying it? 

I was not aware such fossils could be found there, is it common or rather rare? 

Thank you! 

Cheers, 

Romain

Looks like a Glypheidea

Lobsters are pretty rare fossils no matter where you go.

No crustacean known from the Liesberg-layers.

But from the renggeri-Clays Eryma sp. is known.

And from the Terrain à chailles-member Paleopagurus and Orhomalus sp. is known.

I would rule out Eryma, the claws are different to what you have.

The other both might be a candidate if the layer is the correct one.

In every case a rare find - it's a keeper !

That's an awesome specimen! Did you find it in the spill from the Liesberg-layer along the north wall? I didn't realise it could be worth it cracking open the rocks lying on these slopes with a sledge-hammer. But seeing this find, it definitely is...!

Worth only if the site is very small with very few loose specimens. Otherwise nature does the cracking and exposing much better

I agree. That's why I normally don't work with a sledge-hammer unless there's a clear need for it. However, due to all the areas that have been set of for environmental protection, the Liesberg site is actually not all that big - especially not if you consider how high you can safely get up the slopes. So I think it could actually be worth it. But when I was there, I just focussed on the echinoid and crinoid pieces I kept finding, which kept me from feeling the need to chop rocks
