Chopper (Tanzania), 1.85 million years old

This is a Chopper.

This object is not part of the Cooper Hewitt's permanent collection. It was able to spend time at the museum on loan from National Museum of Natural History as part of Tools: Extending Our Reach.

It is dated 1.85 million years old. Its medium is volcanic rock (nephelinite).

Tools crafted and used by our human ancestors appear in the prehistoric record dating back at least 2.6 million years; the earliest tools were made of stone. This simply altered stone, called a "chopper", from the famed archeological site Olduvai Gorge, Tanzania, is around 1.85 million years old. The discovery of such artifacts at Olduvai Gorge gave the name to the world’s oldest Stone Age technology, the Oldowan. Choppers were made using a hammerstone to knap, that is, repeatedly striking off sharp, useful flakes along an edge. The stone is a volcanic rock called nephelinite, from a lava flow south of Olduvai. This basic technology, which produced tools for cutting, pounding, and crushing, enabled humans to obtain new foods and increase the amount of meat, tubers, and roots in their diet.
