Stegosaurs

Christie’s is auctioning the skeletons of an adult and a juvenile Allosaurus, sold as a pair, with an estimated price of between £5–8 million, as well as a Stegosaurus fossil, valued between £3–5 million.

Fossils found in Chile are from a strange-looking dog-sized dinosaur species that had a unique slashing tail weapon, scientists reported on Dec. 1.
