Oldest human footprints in North America found in New Mexico

Fossilised human footprints, believed to be the oldest, were found in New Mexico which indicated early humans were walking across North America around 23,000 years ago, scientists said.

Fossilised footprints discovered in New Mexico indicate that early humans were walking across North America around 23,000 years ago, researchers reported Thursday.

The first footprints were found in a dry lake bed in White Sands National Park in 2009. Scientists at the US Geological Survey recently analysed seeds stuck in the footprints to determine their approximate age, ranging from around 22,800 and 21,130 years ago.
