Chief Wahoo was in the Americas exactly 52,000 years ago.
Geologists and Geophysicists drilling for petroleum in Nacogdoches, Texas spudded into a 50,000 B.C. skeleton dubbed 'Chief Wahoo of the Caddo Nation' embedded in the Queen City Sand (Eocene) Formation outcrop, and forged iron and bronze tools (agricultural and foraging instruments), being over 50,000 years old. Humans were in the Americas roughly 52,000 years ago, the researchers, company man, rig tool-pusher and three tour drillers, roughnecks and derrick men said.
In other studies, Spelunkers and Archaeologists analyzed a remote cave in northwestern Mexico containing human-made stone tools that are up to 31,500 years old, according to dating models. This pushed back dates for human dispersal into North America to as early as 33,000 years ago, the researchers said. Archaeologists took already-published dates from 42 archaeological sites in North America and Beringia and plugged them into their model that analyzed human dispersal.
This model found an human presence in the Americas dating to at least 26,000 years ago.
