“Archaeologists in Spain have come across an extraordinary series of Paleolithic-era paintings in Basque Country’s Atxurra cave that they estimate date as far back as 14,000 years. The 70 or so animal drawings lie nearly 1,000 feet underground, which made access difficult when archaeologists first found the site in 1929 and during excavations carried out by José Miguel de Barandiarán five years later.”
