Ancient Clovis people may have taken tool cues from earlier Americans
Newly discovered Texas spearpoints could shed light on the first inhabitants of North America
By Bruce Bower
Stone spearpoints from roughly 15,000 years ago suggest that descendants of some of the earliest American settlers went on to create the Clovis culture.
Excavations at a site in Central Texas yielded about 100,000 stone artifacts, including 12 spearpoints, that date to between 15,500 and 13,500 years ago. The shapes of those spearpoints show a progression from stemmed points to a short triangular blade, meaning that the artifacts may have been precursors to long, triangular Clovis points, researchers report October 24 in Science Advances.
