An additional specimen of a large-bodied Miocene hominoid from Chiang Muan, northern Thailand.

Chiang Muan is the first Miocene fossil site in Southeast Asia, from which large-bodied Miocene hominoids have been discovered (Kunimatsu et al., Primate Res 16:299, 2000a). In this article, we describe a hominoid lower molar (CMu15-5'01) recovered from the Upper Lignite Member of Chiang Muan.
