The fossilized footprints in New Mexico are at least 21,500 years old, corroborating a momentous 2021 result.
Fossilized human footprints at White Sands National Park in New Mexico are every bit as old as the 23,000 years-and-change they were dated at in 2021, according to new analysis published in Science.
“Although we were confident in the original seed ages, we wanted to develop community confidence in them as well,” said Kathleen Springer, also a geologist with the USGS, in the same release. “Our new ages, combined with the strong geologic, hydrologic, and stratigraphic evidence, unequivocally support the conclusion that humans were present in North America during the last Glacial Maximum.” Radiocarbon dating is a reliable way of dating ancient organic material, but it has shortcomings.

Previously, archaeologists thought human ancestors arrived about 15,000 years ago. The research was published Thursday in the journal Science. Scientists analyzed conifer pollen and quartz grains found at the site to reach date estimates. Earlier research that analyzed seeds of aquatic plants found at the site also produced similar date estimates. Ancient humans at White Sands lived alongside giant ground sloths, bison and other megafauna.
