The huge-sized deinothere Deinotherium proavum (Proboscidea, Mammalia) from the Late Miocene localities Pikermi and Halmyropotamos (Greece)

Abstract

Presented here are the deinotheriid dental and postcranial remains from the Late Miocene localities Pikermi and Halmyropotamos (Greece). The study and comparison of the available juvenile dental material from Pikermi with other relevant specimens from Europe showed that it belongs to the huge-sized Deinotherium proavum (=D. gigantissimum). Additionally, several postcranial specimens from Pikermi, as well as from Halmyropotamos, present deinotheriid features, which distinguish them from elephantoids, and permit their attribution also to D. proavum. This species is known from the Turolian and represents the terminal evolutionary stage of the European deinotheres. Its presence in Pikermi and Halmyropotamos is compatible with the middle Turolian (MN 12) age of the localities. Additionally, the taxonomy of European deinotheres is discussed, as well as the biostratigraphical and geographical distribution of D. proavum. (C) 2016 Elsevier Ltd and INQUA. All rights reserved
