Systematic Study of the New Remains of Propotamochoerus Hysundricus (Suidae, Mammalia) from the Late Miocene-Early Pliocene Middle Siwaliks (Pakistan)
New fossil remains of Propotamochoerus hysudricus have been studied from the Dhok Pathan and Padhri localities of the Middle Siwaliks of Pakistan. Propotamochoerus hysudricus is among one of the best known Siwalik suids with complete skulls, mandibles and isolated specimens. This species is most commonly found suid in the Dhok Pathan and Nagri units of the Siwaliks. The genus Propotamochoerus in Siwaliks is represented only by single species Propotamochoerus hysudricus. The chronological range of the species is about 10-06 million years ago. The probable ancestor of Propotamochoerus is Hyotherium of Chinji Formation about 11 million years ago. The primitive Propotamochoeroides were near to the Palaeochoerus and were treated as precursor of other suinae.
