Rare dinosaur skeleton goes under the hammer for nearly $50 million The skeleton, nicknamed "Judy," belongs to a Nanotyrannus, one of only three known to science. It is 2.9 m high and about 6 m long and is considered to be 70% complete. The remains were discovered in 2019 during excavations in Montana. "Judy" became the second most expensive set of dinosaur bones ever sold at auction. The lot, originally valued at $6-9 million, went under the hammer for $47.3 million. However, the buyer asked to remain anonymous. Only the Tyrannosaurus Rex fossil, nicknamed Goose, was more expensive - it was sold at an auction in New York in July for $50.1 million. The world is burning, and we are in Zen.
