Ancient artists created the works between 12,600 and 11,800 years ago.
oward the end of the last Ice Age, prehistoric artists painted tens of thousands of images—including depictions of mastodons, giant sloths and other now-extinct animals—on cliff walls in the Amazon rainforest, reports Dalya Alberge for the Guardian. Archaeologists found the first of the enormous set of images in 2017 but kept the trove secret while continuing work and preparing a television series on the discovery.

A British-Colombian research team funded by the European Research Council spotted the paintings stretched across eight miles of cliffs in the Serranía de la Lindosa, which is part of the Colombian Amazon. The red-ocher art features fish, lizards, birds, geometric patterns and humans, including people dancing. In at least one image, a human dons a mask suggestive of a bird’s face. Also shown are an extinct camelid known as a palaeolama and a type of horse that lived in the region during the Ice Age.
“The pictures are so natural and so well made that we have few doubts that you’re looking at a horse, for example,” team leader José Iriarte, an archaeologist at Exeter University, tells the Guardian. “The horse had a wild, heavy face. It’s so detailed, we can even see the horse hair. It’s fascinating.”
Live Science’s Laura Geggel reports that ancient artists created the works between 12,600 and 11,800 years ago. At the time, the area was transforming from a landscape of savannas, shrubs and forests into the tropical rainforest seen today. According to team member Mark Robinson, also an archaeologist at the University of Exeter, the people who made the images were probably among the first humans to live in the western Amazon.
“The paintings give a vivid and exciting glimpse the lives of these communities,” says Robinson in a statement. “It is unbelievable to us today to think they lived among, and hunted, giant herbivores, some which were the size of a small car.”
