Remarkably, all the paintings turned out to be well-preserved and incredibly detailed. “The pictures are so natural and so well-made that we have few doubts that you’re looking at a horse, for example. The ice-age horse had a wild, heavy face. It’s so detailed, we can even see the horse hair. It’s fascinating.”

Iriarte also said in a statement that this ancient art serves as spectacular evidence of how humans reconstructed the land, how they lived there, hunted, farmed, and fished. “It is likely art was a powerful part of culture and a way for people to connect socially. The pictures show how people would have lived amongst giant, now extinct, animals, which they hunted,” he concluded.
