CNN —Archaeologists in Spain have discovered prehistoric paintings in hard-to-reach caves in the east of the country using drone technology. The use of drones allowed researchers to quickly gather evidence of previously unseen cave paintings dating from 5,000- 7,500 years ago, according to a statement from the team at the University of Alicante, Spain.
