An article by Dalya Alberge on theguardian.com – ‘Sistine Chapel of the ancients’ rock art discovered in remote Amazon forest – reports on one of the world’s largest collections of prehistoric rock art which has been discovered in the Amazon rainforest.

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. These animals were all seen and painted by some of the very first humans ever to reach the Amazon. Their pictures give a glimpse into a lost, ancient civilisation. Such is the sheer scale of paintings that they will take generations to study.
