Acheulean

Acheulean ( /əˈʃuːliən/; also Acheulian) (from French acheuléen, a term based on the name Saint-Acheul, a suburb of Amiens, the capital of the Somme department in Picardy, where hand-axes of this period were found in 1859), is the name given to an archaeological industry of stone tool manufacture associated with early humans during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, and Europe. Acheulean tools are typically found with Homo erectus remains. It is thought that they first developed out of the more primitive Oldowan technology as long ago as 1.76 million years ago, by Homo habilis.
