Acheulian tools are wide spread in Central and southern, and western India. Recently I discovered numerous Acheulian handaxes and cleavers from the Sir Khad -a tributary of Satluj that flows through Himachal Pradesh and Punjab in Middle Siwalik terrain where Soan pebble culture predominated. The earliest Siwalik pebble tools are regarded~2 million years old and called "Pre-Acheulian". Why not these be the 'Oldowan' indicating the earliest migration of African Oldowan Homo habilis to South Asia.
