The document summarizes important cave paintings from three archaeological sites in Europe:
1) Altamira Cave in Spain contains bison paintings dated to 16,000-9,000 BC, making them some of the oldest known cave paintings.
2) Lascaux Cave in France features paintings of horses, bulls and stags from around 15,000 BC.
3) Chauvet-Pont-d'Arc Cave in France contains animal paintings that may be as old as 32,000 years.
Theories suggest the paintings were used for decoration, magic, or to document hunts, and they were created using tools like bones and natural pigments like ochre.
