Stone age rock paintings near the Sri Nakharin dam reservoir lake in Thailand. Rock paintings were painted on rock and were more naturalistic depictions than petroglyphs. In paleolithic times, the representation of humans in cave paintings was rare. Mostly, animals were painted: not only animals that were used as food but also animals that represented strength like the rhinoceros or large cats (as in the Chauvet Cave). Signs like dots were sometimes drawn. Rare human representations include handprints and half-human/half-animal figures. The Cave of Chauvet in the Ardche dŽpartement, France, contains the most important preserved cave paintings of the paleolithic era, painted around 31,000 BC. The Altamira cave paintings in Spain were done 14,000 to 12,000 BC and show, among others, bisons. The hall of bulls in Lascaux, Dordogne, France, is one of the best known cave paintings from about 15,000 to 10,000 BC.
