At A Site In Northeastern Brazil, Prehistoric Rock Art And 140 Million-Year-Old Dinosaur Footprints Are Brought Together “Like No Archaeological Or Paleontological Site In The World”

Theropods were meat-eating dinosaurs that ranged in size from two to 40 feet, while the long-necked sauropods were the largest creatures ever to walk the Earth.

The petroglyphs were mostly carvings filled with geometric shapes and lines. They were made by ancient humans who lived in the region anywhere between 3,000 and 9,000 years ago.

It is unclear what the symbols represent, but there is an unmistakable connection between the petroglyphs and the footprints.

“They look very much like the initial visions generated by the brain when humans ingest hallucinogens,” Troiano said.

“This and other factors lead me to believe that their creation was embedded in a ritualistic context, probably some kind of consumption ceremony, and the site was selected due to the presence of footprints, and therefore considered important to them.”
