Human footprints found in White Sands National Park, New Mexico, were associated with astonishingly ancient age dates in 2021. New research published in the October 5, 2023 issue of Science reports on two independent age dating techniques that corroborate the third technique. The data show that the footprints are between 23,000 and 21,000 years old. This will require fundamental changes in rewriting our history.
Footprints have many stories to tell. Humans once shared a world with giant creatures, and footprints can be a window into those interactions. From the ancient tracks found in White Sands National Park recently to those found in Africa decades ago, tracks provide reliable evidence of occupation.
Who left the earliest footprints in rocks that we can admire today? From the giant tracks of enormous dinosaurs to the delicate prints of small lizards and birds, I think footprints are fascinating. Tracks preserved for tens of millions of years, as well as those left within hours, can tell interesting stories about people, animals, and their interactions.
