Exquisite Fossil Crab Panopeus from Washington

Description: Among the world’s best-preserved crab fossils are those occurring in western Washington state. Generally the crabs quickly fall apart after death. So for these crabs to be found is so fine a state of preservation in a rarity. They must have been buried soon after death. The crabs are found in concretions along the sides of creeks and beds of local streams. Painstaking work and long hours are required to prepare them.

This Panopeus purpureus is an excellent example. Nine of ten appendages have been at least partially preserved. Note the shiny black color of the carapace and legs. It is fully inflated, well-centered and 3D.
