    These elusive crustaceans are found within the Lincoln Creek formation near Astoria in Washington. During the Eocene, Grays Harbor was a hub of activity for marine life. This was shortly after the dinosaurs went extinct and life was blossoming once again. The Lincoln Creek is primarily formed from siltstone and marine deposited sandstone where concretions containing the ancient remains of crabs and other fossils exist. Calcareous concretions, many of which contain megafossils[1]. Like other crabs (i.e. Fiddler) these crabs have a dominant claw which is aligned on the right side of the crab. There's some evidence online which suggests this dominant claw was used to attract mates, defend themselves, and vie for territory. These crabs are difficult to prepare requiring on average twenty to forty hours of preparation time as the concretion (nodule) they are encapsulated in is condensed. Most of the sites once accessible within the formation are now closed to the public and the lands are now privately owned.
