Oldest Eurasian stone tools

The oldest Eurasian hominoid.

Engelswies is an early Miocene vertebrate locality in southern Germany with a rich assemblage of terrestrial mammals, invertebrates and fossil plants. It is dated to 16.5-17.0 Ma based on magnetostratigraphy, biostratigraphy and lithostratigraphy, and includes among the faunal remains a hominoid upper molar fragment, the oldest hominoid so far identified from Europe. The evidence from Engelswie...

Stone Age hut in Israel yields world's oldest evidence of bedding.

The earliest archaeological remains of dwelling huts built by Homo sapiens were found in various European Upper Paleolithic open-air camps. Although floors of huts were found in a small number of cases, modern organization of the home space that includes defined resting areas and bedding remains was not discovered. We report here the earliest in situ bedding exposed on a brush hut floor. It has...

Defining and measuring reduction in unifacial stone tools

Observations pertaining to particular stages of the lithic chaı̂ne opératoire, or reconstructions of the entire operational sequence at a particular site, can be used to develop a detailed understanding of past human cognitive capabilities, technological sophistication, mobility, and land use. The ‘‘reduction sequence’’ is a specific stage of the chaı̂ne opératoire that many archaeologists have a...

Experimental Insights into the Cognitive Significance of Early Stone Tools

Stone-flaking technology is the most enduring evidence for the evolving cognitive abilities of our early ancestors. Flake-making was mastered by African hominins ~3.3 ma, followed by the appearance of handaxes ~1.75 ma and complex stone reduction strategies by ~1.6 ma. Handaxes are stones flaked on two opposed faces ('bifacially'), creating a robust, sharp-edged tool, and complex reduction stra...
