White Sands fossil footprints

Fossilized human footprints were found in the White Sands National Park in New Mexico which were made between 21,000 and 23,000 years ago.[1][2]

The footprints are located at the shore of an ice age era lake in the Tularosa Basin. As of November 2021, 61 fossil footprints have been found at the site.[3]

In 2022 the dating was questioned, as comparative probes from the immediate vicinity show, that in the aquifer of the site prehistoric water is present with dissolute old ¹⁴C and it will be incorporated in plants growing under these conditions. A shift of the datings by ca. 7000–10.000 Jahre to about 13,350 cal yr BP by this effect can not be excluded.[4]
