The most important contribution made by Clovis people was the Atlatl, a speart-thrower. The atlatl was a stick-like device about two feet long, weighted and fashioned to hold a spear securely. It allowed greater velocity and whip action and enabled the hunter to hit an animal as far away as 300 feet with a great deal of force. Folsom people, the next known inhabitants of Oklahoma, also used the atlatl.
