The Oldowan Industry, also known as Mode 1, is the earliest known stone tool industry in prehistory. It is named after the Olduvai Gorge in Tanzania, where these tools were first discovered.

1. Time Range: The Oldowan Industry dates back to approximately 2.6 million years ago and lasted until about 1.7 million years ago. This period corresponds to the Lower Paleolithic era.

2. Tool Types: The Oldowan tool kit is characterized by simple, usually flaked, tools.

- Choppers: These are the most common tool type found in Oldowan sites. They are typically made from a pebble or chunk of stone that has been struck off a larger piece, creating a sharp edge. One side remains rounded and untouched, while the other side has a sharp, cutting edge.

- Scrapers: These tools are similar to choppers but have a more refined edge. They were likely used for scraping meat off of animal hides or for working with wood.

- Hammerstones: These are hard, rounded stones used to strike off flakes from a core, or to directly process materials like nuts or tubers.

- Cores: These are the pieces of stone that other tools are flaked off from. They can also be used as tools themselves.

The Oldowan Industry represents the beginning of human technology and shows the first evidence of explicit tool manufacture.
