Report: Spearheads excavated in Central Texas are perhaps the oldest in North America local news



A research team led by a Texas A & M University professor believes spearheads excavated in central Texas may be the oldest found in North America, says Science Advances .

The spearheads were found in 2015, about 40 miles northwest of Austin at the Debra L. Friedkin site, named after the owner. Michael Waters, Texas A & M anthropology professor and director of the Center for the Study of the First Americans, said the discovery could change the understanding of when and how the earliest people in North America explored and settled.

Based on the dating of the sediment in which they were found, the researchers estimate that the spearheads are between 1

3,500 and 15,500 years old. This would precede the Clovis culture, which, as Waters said, was for a long time the first people to come to America. The Clovis time frame was 12,700 to 13,000 years. Waters said the discovery of the points is important because, although stone tools were found in almost all places before Clovis, whole spearheads still need to be found.

At Friedkin's location, the new spearheads were found under a layer containing Clovis artifacts. To find such artefacts in deposits just below Clovis artifacts, Waters describes as "the gold standard". The projectile points that were probably used for the hunt had two previously unknown styles, which predated before Clovis. Waters believes that the discovery means that the earlier point style is prior to the Clovis style, which affects migration and how people reached America at the end of the last ice age.

Other researchers on the project were from Baylor University and the University of Texas. Their findings were published on October 24 in the journal Science Advances .
