New insight into the Pleistocene deposits of Monte delle Piche, Rome, and remarks on the biochronology of Hippopotamus (Mammalia, Hippopotamidae) and Stephanorhinus etruscus (Mammalia, Rhinocerotidae) in Italy

摘要: Several large mammal assemblages have been collected in the Roman basin since XIX century, but they usually lack any stratigraphic datum or details about fossiliferous localities. In this work, provenance of remains discovered at Monte delle Piche (Rome) is investigated. The systematic revision these specimens allows recording presence Hippopotamus sp., Stephanorhinus sp. and etruscus . On basis micropalaeontological analysis performed on sediment sampled from studied speci-mens considering stratigraphy area, two levels are recognised Piche.
