Item A Diverse hominoid fauna from the Late Middle Pleistocene breccia cave of Tham Khuyen, Socialist Republic of Vietnam. Anthropological papers of the AMNH ; no. 73(New York, N.Y. : American Museum of Natural History, 1994) Schwartz, Jeffrey H.; Long, Vu The.; Cuong, Nguyen Lan.; Kha, Le Trung.; Tattersall, Ian.The cave of Tham Khuyen in Lang Son Province, northeastern Vietnam, has yielded a large mammalian fauna of probable late middle Pleistocene date. A series of isolated hominoid primate teeth, formerly allocated to the extant orangutan Pongo pygmaeus, has recently been reexamined and found to represent more than one species. These specimens are described in detail in this paper and are analyzed as follows. Some of the teeth are indeed clearly identifiable as those of Pongo pygmaeus, but the majority appear to belong to a species related to the orangutan but not identical with it. A few teeth are distinct from either of the above, both in size and morphology, and are interpreted here as representing a previously undescribed genus and species of a large-bodied hominoid. In addition, a few teeth are regarded as indeterminate at present. With the recognition of this multiplicity of hominoid species at Tham Khuyen, it is evident that the large-bodied hominoid fauna of middle Pleistocene Vietnam was considerably more diverse than formerly supposed, including Gigantopithecus blacki) and Homo sp. in addition to the species noted above.Item A review of the Pleistocene hominoid fauna of the Socialist Republic of Vietnam (excluding Hylobatidae). Anthropological papers of the AMNH ; no. 76(New York, N.Y. : American Museum of Natural History, 1995) Schwartz, Jeffrey H.; Long, Vu The.; Cuong, Nguyen Lan.; Kha, Le Trung.; Tattersall, Ian.We review the nonhylobatid hominoid fauna currently known from all significant Pleistocene sites in Vietnam. Almost all of the sample examined consists of isolated teeth. In a previous study of material from the cave of Tham Khuyen (Schwartz et al., 1994) we identified, but did not name, a new species of Pongo as well as a new genus and species of thick-enameled, nonhominid hominoid. These new taxa are named and characterized in this contribution, as are four new subspecies of Pongo pygmaeus. We additionally note sparse evidence for other taxa whose affinities are not determinable on the basis of available specimens. Most large-bodied hominoid fossils from Vietnam are attributable to the genus Pongo; at most sites only the species Pongo pygmaeus is found. Positive evidence is extremely rare for both Homo and Gigantopithecus in the Pleistocene of Vietnam.
