Oldest fossil human footprints in North America confirmed

New 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.
