These Fossil Footprints Show Humans Were In North America Much Earlier Than Previously Thought.

Sometimes the discoveries are so sensational and interesting that they are able to radically change our conception not only of history but also of places, events, and people. The one we are going to tell you about perfectly demonstrates this and opens up new fascinating perspectives on the lives of our ancestors and the world of yesteryear.

What is the conclusion reached by the researchers? Simple, and at the same time incredible: in North America, the man appeared much earlier than one thought. And by “long” we mean a very long time: 7000 years! How did they find this out? In a rather “classic” way, but no less effective: fossil prints .

We are in the state of New Mexico, in White Sands National Park to be precise. It was there that researchers discovered what has become the oldest fossil footprints ever found in North America. A discovery that upsets the current conception of human settlements in these regions, as well as the movements and migrations of our ancestors.

Sally Reynolds, the co-author of the study and professor at Bournemouth University in England, described the results in detail. “This is unequivocal evidence,” she said. “Before that, we thought humans began to occupy North America around 16,000 years ago. 7,000 years later than in reality, so.

Thanks to a careful dating of these prints, it appeared that they were about 23,000 years old. Most of the footprints, around 60, belong to children and adolescents, but traces of mammoths, wolves, and giant sloths, prey of our fellows at the time, have also been discovered at the site.

It is clear that our ancestors occupied the northern part of the continent during the last ice age , succeeding – contrary to popular belief – in overcoming the dreaded ice caps which blocked their passage south from the regions which today belong to Siberia, Alaska, and Canada.

The fossil footprints were discovered on the shores of an ancient lake bed and leave no room for doubt: humans managed to migrate south despite the harsh conditions and before the ice completely receded. “These footprints are frozen in the landscape,” said Reynolds, “and so it is clear that they cannot be there” by accident. “

Maybe the humans of the day sailed this far across the Pacific, or maybe they arrived by land. It is not known exactly how this happened, but it is certain that they were there, living from the hunt among large creatures now extinct, which seem closer to the imagination than to reality. The giant sloth, for example, was one of their favorite prey, but behemoths, giant armadillos, and prehistoric horses were also present at the time. Testimonies of a real ” megafauna ” would soon die out.

A fascinating find, isn’t it?
