Subsistence behaviors and bone modifications in the early Acheulean in Konso, Ethiopia

Konso area provided several localities 1.9 to 1.4 My aged. These sites provide important data on African lower Pleistocene: the oldest Acheulean assemblage in the world and the coexistence of Australopithecus boisei and Homo erectus, as fossils of both have been found in the same site. On the other hand, the zooarchaeological analysis showed that Konso hominids used to process animal resources with a sharp knowledge of butchery techniques. The great new data actually is the presence of bones that seem to have been shaped in order to be used as tools. (C) 2012 Published by Elsevier Masson SAS.
