Bivalves and gastropods from the West Atlantic (WA) during the Plio-Pleistocene are a well-studied and well-preserved group in the fossil record, and many species from this time period are extant. The periods of global warming during the Plio-Pleistocene can be used as an analog for predicted future climate conditions over the coming centuries, making it possible to form a predictive framework for mollusk survival using the extinct and extant taxa from that time. The present study correlated 16 functional traits, both continuous and categorical, with extinction risk in bivalves and gastropods from the Plio-Pleistocene WA. Traits considered were primarily related to metabolic requirements and predation resistance, both known factors in mollusk survival.
