Carbon dating doesn't work on rock, so the age of stone artifacts has to be determined from the age of items in the matrix in which it was found. David Braun, an archaeologist with George Washington University and the lead author on the paper said; “Given that primate species throughout the world routinely use stone hammers to forage for new resources, it seems very possible that throughout Africa many different human ancestors found new ways of using stone artefacts to extract resources from their environment. These Oldowan toolkits include hammerstones, stone cores, and sharp stone flakes. Donna Strickland and Gérard Mourou were jointly awarded the prize for developing chirped-pulse amplification of lasers, The Ledumahadi Mafube roamed around 200 million years ago in what is now South Africa.
