For 2 weeks, Paula Garci-Medrano, Pierre-Jean Texier and MarieHélène Moncel worked at the National Museum of Nairobi (Kenya). The aim was to studty the lithic collections of the site of Isinya dated to 1 million years.
The analyse has focused on the technological strategies used to make the bifaces and the cleavers and on the cores to compare with the European sites.
The quantity of tools made on phonolithe allow to investigate the large standardization of the shaping process with the use of both hard and soft hammer. Large flakes were produced on big cores and shaped following the same rules.
