Stegosauria

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.

The largest stegosaurus skeleton ever found is expected to fetch millions of dollars at auction in New York next week, likely fueling objections from paleontologists.

The fossil, estimated to be approximately 150 million years old, was put on display at Sotheby's on July 10 and will be exhibited there until its sale on July 17.

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.
