Fossil human footprints discovered in White Sands, New Mexico likely date back to between 21,000 and 23,000 years ago, according to two lines of scientific evidence published Thursday, Oct. 5, 2023. ALBUQUERQUE, N.M.
That’s considerably earlier than once-conventional wisdom, which set the arrival of humans in North America about 15,000 years ago, shortly before rising sea levels covered the land bridge between Russia and Alaska, but some researchers raised concerns about the dates.
“This is a subject that’s always been controversial because it’s so significant — it’s about how we understand the last chapter of the peopling of the world,” Thomas Urban, an archaeological scientist at Cornell University, who was involved in the 2021 study but not the new one, told the AP.

Oldest fossil human footprints in North America confirmedNew research reaffirms that human footprints found in White Sands National Park, NM, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought. In September 2021, scientists announced that ancient human footprints discovered in White Sands National Park were between 21,000 and 23,000 years old. This discovery pushed the known date of human presence in North America back by thousands of years and implied that early inhabitants and megafauna co-existed for several millennia before the terminal Pleistocene extinction event. In a follow-up study, researchers used two new independent approaches to date the footprints, both of which resulted in the same age range as the original estimate.
