Early Oldowan tools are also known from Gona in Ethiopia (near the Awash River), and are dated to about 2.6 Ma. [11] The use of tools by apes including chimpanzees [12] and orangutans [13] can be used to argue in favour of tool-use as an ancestral feature of the hominin family. [14]
Tools classified under this category are known as the earliest indicators of hand axe usage. The biggest difference from the early Oldowan tools, or choppers, is the fact that two sides have had flakes chipped off, versus the single side of the chopper.
Better known are the later tools belonging to an industry known as Oldowan, after the type site of Olduvai Gorge in Tanzania. The tools were formed by knocking pieces off a river pebble, or stones like it, with a hammerstone to obtain large and small pieces with one or more sharp edges. The original stone is called a core; the resultant pieces ...
It includes sites where compelling evidence of hominin tool use has been found, even if no actual tools have been found. Stone tools preserve more readily than tools of many other materials. [1] [2] So the oldest tools that we can find in many areas are going to be stone tools. It could be that these tools were once accompanied by, or even ...
Oldowan tools occur in Beds I–IV at Olduvai Gorge. Bed I, dated 1.85 to 1.7 mya, contains Oldowan tools and fossils of Paranthropus boisei and Homo habilis, as does Bed II, 1.7 to 1.2 mya. H. habilis gave way to Homo erectus at about 1.6 mya, but P. boisei persisted. Oldowan tools continue to Bed IV at 800,000 to 600,000 before present . A ...
At the nearby Gona site, where there is an abundance of raw materials, several Oldowan tools (an industry previously believed to have been invented by H. habilis) were recovered from 1992 to 1994. The tools date to around 2.6–2.5 mya, the oldest evidence of manufacturing at the time, and since A. garhi was the only species identified in the ...

Oldowan tools infrequently exhibit retouching and were probably discarded immediately after use most of the time. [57] The Oldowan was first reported in 1934, but it was not until the 1960s that it become widely accepted as the earliest culture, dating to 1.8 mya, and as having been manufactured by H. habilis.
