N1 - Funding Information:
The Gona Project would like to thank the Authority for Research and Conservation of Cultural Heritage (ARCCH) of the Ministry of Culture and Tourism and the National Museum of Ethiopia (NME) for research permit and support. Major support for this research was provided by the L.S.B. Leakey Foundation (S.S.) , and additional funding for field and laboratory research was provided by the U.S. National Science Foundation ( NSF SBR-9818353 to S.S.; NSF HOMINID-RHOI BCS-0321893 to Tim White and F. Clark Howell; NSF SBR-9727519 to S.W.S.), CWRU Research Initiation Grant (S.W.S.), the National Geographic Society (S.S.; J.Q.), and Wenner-Gren Foundation (S.S.). We appreciate the hospitality of the Afar Regional State administration at Semera and our Afar colleagues from Eloha. Fieldwork participants included Asahamed Humet, Yasin Ismail Mohamed, Wegenu Amerga, Mohamed Ahmedin, Kampiro Qairento, Bizuayehu Tegegne, Emma Smith, Melanie Everett, Steve Frost, and Stephanie Melillo. We thank Y. Haile-Selassie and L. Jellema of the Cleveland Museum of Natural History, Cleveland, Ohio, USA and the curators and staff at the Royal Museum for Central Africa in Tervuren, Belgium for allowing us to examine materials in their care. We thank E. Smith for collecting comparative enamel thickness data in African apes. A number of researchers contributed to the faunal identifications: F. Bibi, J.-R. Boisserie, R. Bernor, S. Frost, I. Giaourtsakis, Y. Haile-Selassie, A. Murray, K. Stewart, H. Saegusa, L. Werdelin. Discussions with and comments by Y. Haile-Selassie, G. Suwa, S. Frost, and D. Weldegeorgis were helpful. The digital image of ALA-VP-2/10 was generously provided by Y. Haile-Selassie. The reviewer's comments were very helpful. The patience of and assistance by D. Begun is greatly appreciated.

N2 - Since 2000, significant collections of Latest Miocene hominin fossils have been recovered from Chad, Kenya, and Ethiopia. These fossils have provided a better understanding of earliest hominin biology and context. Here, we describe five hominin teeth from two periods (ca. 5.4Million-years-ago and ca. 6.3Ma) that were recovered from the Adu-Asa Formation in the Gona Paleoanthropological Research Project area in the Afar, Ethiopia that we assign to either Hominina, gen. et sp. indet. or Ardipithecus kadabba. These specimens are compared with extant African ape and other Latest Miocene and Early Pliocene hominin teeth. The derived morphology of the large, non-sectorial maxillary canine and mandibular third premolar links them with later hominins and they are phenetically distinguishable and thus phyletically distinct from extant apes.
