DALLAS (AP) — Anthropology researchers have found spearheads in Central Texas that the team's leader says are the oldest hunting tools discovered so far in North America, according to a report published this week in the journal Science Advances.

The spear points, hewn of limestone, were found in 2015 at a dig near Buttermilk Creek, which is about 45 miles (72.4 kilometers) north of Austin, said Michael Waters, the Texas A&M University anthropologist who led the study and director of the university's Center for the Study of First Americans.
