Unidentified Eocene crab

[concealedcrab]

Found in the Cozy Dell Shale.

Ventura County, CA.

I believe there are two specimens of Brachyura on the plate (micaceous siltstone). I can’t believe it, I screamed when I found it. We were mostly finding small fragments of legs up until this, and spent a good time searching for more with no luck.
 

There were other shallow water fossils found in the same locality (bivalves, turrids, callista and brittlestars)

Oops, apologies, the Callista was found at a site nearby, not this locality. My mistake!

This looks like some sort of spider crab (Majoidea)  to me. 
And I only see one?

wow... cool find.  I also see only one long legged crab.

I agree, probably a spider crab.

(Possibly also Epialtidae)

The other one is very small but has a imprint at the top of the plate, here is another photo.

King crab maybe? Not sure if it has 8 legs

Curious, great find! Eocene?

Hey everyone!

 

I got in contact with Torrey Nyborg, west-coast decapod expert, and he’s looking at it now. It’s likely a new species!
