Eocene decapod crustaceans from Pulali Point, Washington

Abstract

A robust decapod fauna, including ten species in nine genera, has been recovered from the Eocene ?Aldwell Formation near Pulali Point, Washington. New taxa include Portunites macrospinus n. sp., Carpilius occidentalis n. sp., Pulalius dunhamorum n. gen. and sp. Pulalius vulgaris (Rathbun, 1926) new combination has been removed from Zanthopsis McCoy. Paleopinnixa rathbunae new name is offered as a replacement name for Pinnixa eocenica Rathbun which is herein referred to Paleopinnixa Via. Palaeopinnixa is placed within the Hexapodidae. This is the first notice of Carpilius Leach in Desmarest in the eastern Pacific region. The decapod fauna is typical of those previously reported from deep-water, continental slope settings of the Pacific Northwest with the exception of the occurrence of Carpilius, which has a mainly tropical distribution, and Palaeopinnixa which has previously been reported primarily from lower-latitude settings.
