First identification of Decennatherium Crusafont, 1952 (Mammalia, Ruminantia, Pecora) in the Siwaliks of Pakistan

Abstract

Previously undescribed remains of a new large giraffid have been identified from the late Miocene Siwaliks Hills of the Potwar Plateau in Pakistan. This taxon is very intimately related to the late Miocene giraffid genus Decennatherium, previously only certainly identified in the Iberian Peninsula, and with some possible remains assigned to Decennatheriumcrusafonti from Aliäbäd (Iran). The new material collected in the Siwaliks Hills shows a high morphological similarity with the Spanish remains of the genus, especially the early Vallesian Decennatherium pachecoi. Two previously undescribed ossicone fragments from the same area are also described and identified as cf. Decennatherium. These findings represent the easternmost occurrence of the genus Decennatherium and show a late Miocene migration of the genus throughout the Iberian Peninsula and Southern Asia.
