First Hominoid from the Late Miocene of the Irrawaddy Formation (Myanmar) Jaeger, Jean-Jacques Aung Naing Soe Chavasseau, Olivier Coster, Pauline Emonet, Edouard-Georges Guy, Franck Lebrun, Renaud Aye Maung Aung Aung Khyaw Hla Shwe Soe Thura Tun Kyaw Linn Oo Rugbumrung, Mana Bocherens, Herve Benammi, Mouloud Chaivanich, Kamol Tafforeau, Paul Chaimanee, Yaowalak For over a century, a Neogene fossil mammal fauna has been known in the Irrawaddy Formation in central Myanmar. Unfortunately, the lack of accurately located fossiliferous sites and the absence of hominoid fossils have impeded paleontological studies. Here we describe the first hominoid found in Myanmar together with a Hipparion (s.l.) associated mammal fauna from Irrawaddy Formation deposits dated between 10.4 and 8.8 Ma by biochronology and magnetostratigraphy. This hominoid documents a new species of Khoratpithecus, increasing thereby the Miocene diversity of southern Asian hominoids. The composition of the associated fauna as well as stable isotope data on Hipparion (s.l.) indicate that it inhabited an evergreen forest in a C3-plant environment. Our results enlighten that late Miocene hominoids were more regionally diversified than other large mammals, pointing towards regionally-bounded evolution of the representatives of this group in Southeast Asia. The Irrawaddy Formation, with its extensive outcrops and long temporal range, has a great potential for improving our knowledge of hominoid evolution in Asia. 2011 http://hdl.handle.net/20.500.12678/0000002599 https://meral.edu.mm/records/2599
