Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens. Ar/Ar ages, biostratigraphy, and tephrachronology from this area indicate that the Pleistocene Bodo hominid cranium and newer specimens are approximately 0.6 million years old. Only Oldowan chopper and flake assemblages are present in the lower stratigraphic units, but Acheulean bifacial artifacts are consistently prevalent and… Expand
Chronology of the Acheulean to Middle Stone Age transition in eastern Africa
The age of late Acheulean tool assemblages was determined from 615,000 to 499,000 years ago, after which a large technological and faunal transition occurred, with a definitive MSA lacking AcheULEan elements beginning most likely by ~320,000 Years ago, but at least by 305,000years ago, establishing the oldest repository of MSA artifacts in eastern Africa.

Initial 26Al/10Be burial dating of the hominin site Bailong Cave in Hubei Province, central China
With the discovery of Homo erectus teeth, stone artifacts and a rich fauna, Bailong Cave in northern Hubei Province is an important hominin/archaeological site in China. However, due to the lack ofExpand
Geoscience methods lead to paleo-anthropological discoveries in afar rift, Ethiopia
With few exceptions, most of the hominid evolutionary record in Africa is closely associated with the East African Rift System. The exceptions are the South African and Chadian hominids collectedExpand
Mio-Pliocene mammals from the Middle Awash, Ethiopia
Abstract The Middle Awash paleontological study area, located in the Afar Rift of Ethiopia, has yielded fossils spanning the last six million years. The geology and geochronology of the Mio-PlioceneExpand

The Pleistocene fauna (other than Primates) from Asbole, lower Awash Valley, Ethiopia, and its environmental and biochronological implications
The Asbole area in the Lower Awash Valley yielded a diverse fauna of large and small mammals, associated with an Acheulean industry. The most notable forms are a potentially new species of herpestid,Expand
Hominin technological behavior during the later middle Pleistocene in the Gademotta formation, main Ethiopian rift
The evidence now strongly supports an African origin of the first Homo sapiens. Currently, the best-known fossil evidence for the earliest H. sapiens derives from the Omo Kibish and Herto sites inExpand
Age of Maba hominin site in southern China: Evidence from U-series dating of Southern Branch Cave
Maba hominin, one of the key representatives of archaic Homo sapiens in China, was originally attributed to around the Middle-Late Pleistocene transition (similar to 130 ka) based on biostratigraphicExpand
Mass spectrometric U-series dating of the Chaoxian hominin site at Yinshan, eastern China
The fossils of Chaoxian hominin, widely accepted as representing archaic Homo sapiens in eastern China, were recovered from the middle or slightly higher levels of Layer 2 deposits of a collapsedExpand
Archaeology of middle Pleistocene lacustrine and spring paleoenvironments in the Kapthurin Formation, Kenya
The oldest evidence for systematic blade production can be found at these sites, indicating that important technological innovations were appearing at this time, as small-scale technological innovation allowed for more behavioral flexibility in response to rapid environmental change in a arid, mosaic environment.

Age of the earliest known hominids in Java, Indonesia.
The hominid fossils, a juvenile calvaria of Pithecanthropus and a partial face and cranial fragments of Meganthropus, commonly considered part of the Asian Homo erectus hypodigm, are at least 0.6 million years older than fossils referred to as Homo erectu from Olduvai Gorge, Tanzania, and comparable in age with the oldest Koobi Fora Homo cf.
