Fossil - Pea Crab Pinnixa sp.An abundant medium growing crab species found in the shallow seabed of the middle Miocene Monterey Formation, Pea Crabs of the genus Pinnixa lived in what is now modern day California approximately 12 16 million years ago. Beautifully preserved on slabs of flat shale, the crab fossil's color can vary from brown to gold depending on what minerals were present at time of fossilization. These unique fossil specimens show excellent articulation and detail

Also known as antimonite
