White Sands and other finds challenge the Clovis-first model

Source: The Forgotten Evidence of Humans in America ~200,000 Years Ago by Luke Caverns

White Sands footprints are independently dated to roughly 21,000–23,000 years ago, and Page-Ladson evidence to about 14,500 years ago. Meadowcroft’s early occupation evidence dates to about 19,000–23,000 years ago. The video argues that the “G Site” in Texas, Pedra Furada, Serra da Capivara and Calico add pre-Clovis evidence, but their proposed old dates remain disputed. It also cites marrow extraction at a mammoth-tusk site near San Diego and says pre-Clovis deposits can lie 20 feet underground. These finds challenge a Clovis-first model. 🌎

Key facts

Independent dating places the White Sands human footprints at roughly 21,000–23,000 years ago.
Meadowcroft Rockshelter's early-occupation evidence is dated to about 19,000–23,000 years ago; 16,000 years is not its earliest date.
Page-Ladson evidence dates to about 14,500 years ago.
The video proposes disputed pre-Clovis dates for the “G Site” in Texas, Pedra Furada, Serra da Capivara and Calico Early Man; these are not settled dates.
Serra da Capivara—not “Sero Capa”—is the Brazilian rock-art site in the video's account. Pedra Furada is a separate disputed early-occupation claim.
The video cites marrow-extraction evidence at a mammoth-tusk site near San Diego and says pre-Clovis deposits can lie about 20 feet underground.
