Description

Crustacean
Upper Miocene
Monterey Formation
Monterey County, California, USA

70mm and 40mm crabs on 160mm slab. Very rare for the Monterey Formation.

This is a unique specimen from a site known for the pea crab, Pinnixa galliheri.  At least two other crab taxa are known from there but they are quite rare and apparently undescribed.
