Abstract

The Haritalyangar (India) local fauna contains type specimens of several hominoid primates which are assigned a new last appearance datum age based on a magnetic polarity stratigraphy. This youngest assigned age for Sivapithecus indicus, S. sivalensis and Ramapithecus punjabicus in Asia is about 7.0-7.5 m.y. The age of the holotype specimen of Gigantopithecus bilaspurensis is about 6.3 m.y. The Nahan Sandstone Formation is at least in part contemporary with the Nagri Formation (lithofacies) of the Potwar Plateau, Pakistan.
