Oldowan Tools from Lokalalei, Kenya

Early humans in East Africa used hammerstones to strike stone cores and produce sharp flakes. When these stone flakes were removed from this stone core from, it also created sharp edges. For more than 2 million years, early humans used these tools to cut, pound, crush, and access new foods—including meat and bone marrow from large animals.
