Archeologists have found nearly 5,000 cave paintings made by hunter-gatherers in a northeastern Mexico mountain range where pre-Hispanic groups were not known to have existed. The yellow, red, white and black paintings depict humans, deers, lizards and centipedes, suggesting that the groups hunted, fished and gathered food, according to the National Anthropology and History Institute (INAH). They also painted religious, astronomical and abstract scenes and most of the images are very well preserved.

Stunning reproductions of the famed cave paintings of Lascaux are being displayed for the first time outside of France at an exhibit in Chicago opening Wednesday. Meticulously copied to the millimeter, these full-sized replicas are one of the only way to see these images, since the cave was closed to the public in 1963 in order to preserve the ancient masterpieces.
