Descrição

New data led us to revise Miocene Perissodactyla from Lisbon. Equids (Anchitherium) have been decribed by Alberdi & González (1999); we fully agree with their conclusions. On the other hand, the only Chalicotheriid cannot be clearly reported to any genus. It therefore will be left in open nomenclature Schizorheriinae ind.). The Rhinocerotids have been described in detail (1983). We could recognize now that: Protaceratherium sagicum is a synonym of P. minutum; Plesiaceratherium platyodon and Plesiaceratherium lumiarense should be ascribed to the genus Plesiaceratherium and not to Aceratherium; there are no reasons for name changes as far as the forms previously referred as Diaceratherium aurelianensis, Prosantorhinus germanicus and Hispanotherium matritensis are concerned; as the genera Dicerorhinus and Lartetotherium are distinct, Dicerorhinus (Lartetotherium) sansaniensis has to be named Lartetotherium sansaniensis; as Gaindatherium (Ïberotherium) rexmanueli cannot be reported to Gaindatherium, we therefore upgrade the subgenus Iberotherium to the genus'rank - hence the names of the concerned taxa become Iberotherium rexmanueli rexmanueli and I. rexmanueli zbyszewski; Chilotherium ibericus is but a dental variation of I. rexmanueli zbyszewski. The stratigraphic distribution and age of the Miocene Perissodactyla so far known in the Lower Tagus basin / Lisbon region are presented.
