Malacostracan crustacean fauna from the Sundance Formation (Jurassic) of Wyoming. American Museum novitates ; no. 2652

Abstract

"The only marine Jurassic decapod fauna in North America is found in the Stockade Beaver Member of the Sundance Formation of Wyoming. The preservation of these crustaceans is only moderately good, permitting, at most, identification to the generic level of these soft-shelled decapod shrimp. The faunal assemblage, composed of Antrimpos sp., Bombur sp., Mecochirus sp., a glypheid, and some unidentifiable anomuran remains, can be compared with Triassic and Jurassic material from European deposits, which form part of the biologic continuum of crustaceans throughout the Lower Mesozoic"--P.
