Decapod Crustaceans from the Puente Formation (Late Middle to Early Late Miocene), California: A Possible Mass DeathBulletin of the Southern California Academy of Sciences
AbstractDecapod crustaceans are reported for the first time from the late middle to early late Miocene Puente Formation, Riverside County, California. A single specimen of penaeid shrimp and numerous cancrid crabs, referred to Metacarcinus danai Nations, were collected in association with a mixed assemblage of terrestrial plants, a few bivalves, marine mammals, and numerous taxa of microfossils. Living species of Metacarcinus are found in temperate, normal-marine conditions in water depths up to about 100 m. Thus, an inner shelf, shallow- water environment of deposition is postulated for this part of the Puente Formation. The accumulation of many articulated fossils suggests rapid killing and burial of many individuals, suggestive of a mass death.
