Pinnixa galliheri Rathbun
Middle Miocene (Mohnian)
Aguajito Shale Member, Monterey Fm.
Carmel, California, USA

Big 280mm slab with 8 crabs on matrix. One of the best multiple plates we have ever had.

Pinnixa is a genus of pea crab that appeared during the Miocene and still lives today and is a delicacy in some cultures. Fossil specimens are found in various parts of the world…California, Mexico, the Carolinas, and Malaysia.

This may be the freshest-looking crab we’ve ever seen out of the Miocene, but we don’t recommend eating it.
