What tools were made in the Oldowan industry?

The Oldowan industry, dating to approximately 2 million years ago, is characterized by simple, non-standardized stone tools primarily fashioned from pebbles of quartz, quartzite, or basalt.1

The primary implements produced in this industry include:

• Choppers: Often called pebble tools or chopping tools, these were general-purpose implements created by using a hammerstone to strike a few large flakes off a waterworn pebble. This process created a sharp, roughly serrated crest at one end, suitable for hacking, mashing, cutting, scraping, or breaking bones for marrow.12
• Flakes: These were the sharp-edged pieces struck from the pebble cores during the toolmaking process. They were frequently utilized as tools in their own right for light cutting and scraping tasks.123
• Hammerstones and Anvils: These were used in the production process and are often found in association with the finished artifacts.2
• Bone and Wood Tools: While stone is the most preserved material, evidence suggests that early hominids also utilized bone tools, such as a lissoir found at Olduvai Gorge, and likely used wood, though organic materials have rarely survived.1
