A Tyrannosaurus rex fossil billed as one of the world’s largest and most complete specimens was sold for a record $50.1 million Tuesday to a mystery bidder.
Sotheby’s said the 67-million-year-old fossil, nicknamed “Gus,” is now the most expensive set of dinosaur bones ever auctioned off, besting the almost $45 million price tag for a nearly complete stegosaurus sold by the same New York auction house in 2024. The previous record holder had been a Tyrannosaurus rex skeleton nicknamed “Stan” that sold for nearly $32 million in 2020.
“Gus is not only an exceptional find, but a specimen that’s been excavated, documented, prepared, and cared for with real excellence,” Cassandra Hatton, Sotheby’s vice chair, said after the sale was completed. “The market responds when great specimens are taken care of in the right way.”
Why the bidding for this T. rex was intense
Standing upright with its tail extended and right foot slightly raised, “Gus” is an adult dinosaur specimen measuring about 12 ½ feet (3.8 meters) tall and 38 feet (11.5 meters) long.
