The Friedkin site in Texas is dated to about 15,500 years old, and the Gault site in Texas is dated to about 16,000 years old.
Notes on verification
Multiple independent sources, including peer-reviewed Science Advances papers (Waters et al. 2018; Williams et al. 2018) and reputable science journalism outlets, corroborate both dates. These findings support pre-Clovis human presence in the Americas, a topic with strong scientific consensus backing. [tier=gold indep_score=0.867 clusters=3 claim_tier=notable]
