A diverse assemblage of large mammals is spatially and stratigraphically associated with Ardipithecus ramidus at Aramis. The most common species are tragelaphine antelope and colobine monkeys. Analyses of their postcranial remains situate them in a closed habitat. Assessment of dental mesowear, microwear, and stable isotopes from these and a wider range of(More)
The origin of Australopithecus, the genus widely interpreted as ancestral to Homo, is a central problem in human evolutionary studies. Australopithecus species differ markedly from extant African apes and candidate ancestral hominids such as Ardipithecus, Orrorin and Sahelanthropus. The earliest described Australopithecus species is Au. anamensis, the(More)
It has been proposed that the pliopithecid Anapithecus hernyaki was hunted by the ape Dryopithecus brancoi based on analyses of the age and sex distribution of 25 individuals from the late Miocene site of Rudabánya, Hungary (ca. 10 Ma). In this study, the minimum number of individuals (MNI) and age distribution of the assemblage are recalculated and(More)
The Lemudong'o Formation in the Narok District of Kenya comprises a 135-m-thick series of predominantly lacustrine and lake basin margin sedimentary rocks with interstratified primary and reworked tuffs. The formation, deposited ,6 Ma, records deposition within the second of three sequential lake basins created by tectonic and volcanic activity on the(More)

The palaeobiological record of 12 million to 7 million years ago (Ma) is crucial to the elucidation of African ape and human origins, but few fossil assemblages of this period have been reported from sub-Saharan Africa. Since the 1970s, the Chorora Formation, Ethiopia, has been widely considered to contain ~10.5 million year (Myr) old mammalian fossils.(More)
