23,000-year-old human footprints discovered in New Mexico

New research has confirmed what may be the oldest known evidence of humans in North America – a set of 23,000-year-old fossilized footprints found in White Sands National Park, New Mexico.
These footprints, left behind by Ice Age people in the soft mud of an ancient lake bed, are offering a remarkable glimpse into life tens of thousands of years ago.
The findings, published in Science, solidify previous radiocarbon dating and reinforce a new narrative: that humans inhabited North America at least 10,000 years earlier than previously believed.
The site features hundreds of prints left by children, teenagers, and adults walking along a wet lakeshore during the Last Glacial Maximum, a time when most of North America was locked in ice.
Among the many human footprints are those of extinct megafauna — mammoths, dire wolves and giant ground sloths — that offer a glimpse into an ecosystem that no longer exists. “ There were hungry predators around, including dire wolves and saber-toothed cats, ” lead author Matthew Bennett said, according to Smithsonian. “We can see where she slipped in the mud at certain points. … We can also see the footprints of the child where she put it down, presumably because she was tired and needed a rest.”
