Dr. Philip Riris from the Institute of Archaeology at University College London and colleagues have mapped a series of rock engravings (petroglyphs), some of which are thought to be up to 2,000 years old, in the Amazonas state of Venezuela.
The Venezuelan petroglyphs are located in the Atures Rapids area of the Amazonas state, historically reported as the home of the native Adoles by Jesuit priests.
