Researchers in the Amazon rainforest uncovered an extraordinary “canvas” made up of drawings of mastodons, giant sloths and other extinct beasts, which is up to 12,600 years old.
The ancient artists used the red pigment ochre to create the monumental artwork, which spans some 13 kilometres (eight miles) of rock on the hills of the Colombian Amazon.
"These really are incredible images, produced by the earliest people to live in western Amazonia," University of Exeter archaeologist Mark Robinson, who published a paper on the historic discovery in the journal Quaternary International, said in a statement .
Robinson and his team believe that indigenous people began painting these images at the archaeological site of Serranía La Lindosa, on the northern edge of the Colombian Amazon, towards the end of the last ice age.
