Three Fossil Pea Crabs (Pinnixa) From California - Miocene

This is cluster of three, 8 million year old fossil "pea crabs", Pinnixa galliheri from the Monterey Formation of California. They show fine detail with carapace, legs and claws preserved with a brown-orange coloration against the light colored shale. The orange coloration is due to iron oxide.

There are portions of incomplete pinnixa crabs throughout the rock, including a full, unmentioned, complete crab on the back side of the rock. This specimen comes with an acrylic display stand.
