Abstract

A small number of large hominoid specimens are known from the late Miocene of Turkey. (This paper focuses on the two specimens known until 1996. New fossils described by Alpagut et al. ([1996] Nature 382:349-351) are briefly discussed in this paper as well.) Among these, a fragmentary mandible is the type specimen of Ankarapithecus meteai. Another specimen, a partial face, is from the same taxon. Based on the morphology of this face, Ankarapithecus meteai was synonymized with Sivapithecus (Andrews and Tekkaya [1980], Paleontology 23:85-95). The facial specimen was recently restored by the authors, exposing much anatomy that had previously been obscured. The new anatomical details reveal many important differences from Sivapithecus and justify a revision of the nomen Ankarapithecus. Ankarapithecus was a large hominid (great apes and humans) in the clade that also includes Sivapithecus and Pongo. Sivapithecus and Pongo share derived characters not found in Ankarapithecus, which is thus the sister clade to the Sivapithecus-Pongo clade. While the results of this analysis support the sister relationship of Sivapithecus and Pongo, there is some uncertainty regarding paleobiogeographic and taxonomic relationships to the large hominids from the Siwaliks. An Ankarapithecus-like taxon may have been ancestral to Sivapithecus, or an early Siwalik (Chinji formation) taxon, which predates both Sivapithecus sensu stricto and Ankarapithecus, may be ancestral to both.
