Article: Upper Miocene anthropoids from the Siwalik beds of Haritalyangar, Himachal Pradesh, India
K. N. Prasad
The Nagri beds at Haritalyangar contain a rich mammalian fauna. The present paper deals primarily with the description of the primate fossils collected by the author in 1954 and 1962. A maxillary fragment consisting of three molars is assigned to Sivapithecus sivalensis. In addition, a few isolated upper and lower molars, an upper canine, and an upper premolar, belonging to different genera of anthropoid apes, have been briefly outlined. A lower third molar of Sugrivapithecus gregoryi has also been recovered for the first time.The primates collected from Haritalyangar are generally in the form of isolated teeth and broken fragments of mandible, the upper dentition being markedly scarce. This is rather difficult to explain. The total absence of limb bones and skulls, the fragmentary condition of the mandibles and maxillae, and the large concentration of hyaenodonts in the sediments suggest that the hominoids were devoured by these predacious animals.
