Dispersal patterns of Eurasian hominoids: implications from Turkey
A key to understanding the complex pattern of hominoid dispersals, origins, and extinction is the fossil evidence from Turkey. Miocene localities in Turkey are known to contain taxa from across Eurasia and Africa, and even North America. Three or four separate hominoid clades are identified in Anatolia, more than in any other place except Kenya. Each of these clades has its closest affinities w...
متن کاملEnamel thickness, microstructure and development in Afropithecus turkanensis.
Afropithecus turkanensis, a 17-17.5 million year old large-bodied hominoid from Kenya, has previously been reported to be the oldest known thick-enamelled Miocene ape. Most investigations of enamel thickness in Miocene apes have been limited to opportunistic or destructive studies of small samples. Recently, more comprehensive studies of enamel thickness and microstructure in Proconsul, Lufengp...
متن کاملDietary Specialization during the Evolution of Western Eurasian Hominoids and the Extinction of European Great Apes
Given the central adaptive role of diet, paleodietary inference is essential for understanding the relationship between evolutionary and paleoenvironmental change. Here we rely on dental microwear analysis to investigate the role of dietary specialization in the diversification and extinction of Miocene hominoids from Western Eurasian between 14 and 7 Ma. New microwear results for five extinct ...
متن کاملMolar crown formation in the Late Miocene Asian hominoids, Sivapithecus parvada and Sivapithecus indicus.
During the past decade, studies of enamel development have provided a broad temporal and geographic perspective on evolutionary developmental biology in Miocene hominoids. Here we report some of the first data for molar crown development in one hominoid genus, Sivapithecus. The data are compared to a range of extant and extinct hominoids. Crown formation times (CFTs), daily rates of enamel secr...
متن کاملPreliminary investigation of dental microstructure in the Yuanmou hominoid (Lufengpithecus hudienensis), Yunnan Province, China.
Fieldwork in the Yuanmou Basin of southern China has uncovered a large assemblage of late Miocene hominoid fossils assigned to Lufengpithecus hudienensis. Two mandibular first molars from this species were made available for histological analysis as part of a larger ongoing study on the ontogeny of dental development in Miocene to Recent hominoids. Results are compared with published and unpubl...
