Study reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction of large ice age mammals.
The study, featured on the Dec. 4 cover of the journal Science Advances, used stable isotope analysis to model the diet of the mother of an infant discovered at a 13,000-year-old Clovis burial site in Montana. For example, the animal parts left at Clovis sites are dominated by megafauna, and the projectile points are large, affixed to darts, which were efficient distance weapons,” said co-lead author Ben Potter, an archaeology professor at the University of Alaska Fairbanks. Other authors of the paper include Stuart J. Fiedel, independent researcher; Juliet E. Morrow, University of Arkansas; and Christopher N. Jass, Royal Alberta Museum.
