Researchers have made public photos of some amazing prehistoric engravings found in a cave in western France. The engravings in the Cussac Cave in the Dordogne Valley are estimated at up to 28,000 years old and are being hailed as a major discovery. The size and condition of the engravings are especially impressive, covering the walls with images of mammoths, rhinoceroses, horses, birds, and erotic feminine figures. The cave has already been classified as a national monument, and it is highly unlikely that it will ever be opened to the public. However, French officials have raised the possibility of constructing a replica in a nearby cave. Coverage and photos are available from the BBC, Times, Discovery News, Archaeology Magazine, and Le Monde.
