Choppers are crude forms of stone tool and are found in industries as early as the Lower Palaeolithic from around 2.5 million years ago. These earliest known specimens were found in the Olduvai Gorge in Tanzania by Louis Leakey in the 1930s. The name Oldowan was given to the tools after the site in which they were excavated. These types of tools were used an estimated time range of 2.5 to 1.2 million years ago.[1]
