"Hailed as “the Sistine Chapel of the ancients”, archaeologists have found tens of thousands of paintings of animals and humans created up to 12,500 years ago across cliff faces that stretch across nearly eight miles in Colombia.

Their date is based partly on their depictions of now-extinct ice age animals, such as the mastodon, a prehistoric relative of the elephant that hasn’t roamed South America for at least 12,000 years. There are also images of the palaeolama, an extinct camelid, as well as giant sloths and ice age horses."
