Fossil decapod crustaceans from the lower Tertiary of the Prince William Sound Region, Gulf of Alaska
Sixty-five fossil brachyuran crabs, collected from rocks of the Orca Group, Tokun Formation, and Poul Creek Formation, have been assigned to six species, five of which were described previously. One of these, Pilumnoplax hannibalanus , is reassigned to Neopilumnoplax. Morphologic descriptions of Ran...
