New Quaternary fossils from high elevation cave deposits in Cuba

Abstract

High elevation fossil deposits in Cuba have been poorly studied, and there is a limited understanding of how altitudinal changes could have affected the composition of faunal communities in the past. Here, we report fossils of 13 vertebrate species and an invertebrate from 11 late Quaternary cave deposits at elevations ranging from 532 to 1123 meters above sea level, located in the Guamuhaya Masiff in central Cuba. The composition of the vertebrate fauna assemblages recovered from these localities resembles that known from other lowland deposits and includes eight extinct, one extirpated, and four extant species. Furthermore, the specimens reported here record the highest elevation known for nine species recovered.
