A nearly complete Tyrannosaurus rex skeleton nicknamed “Gus” sells for a record $50.1 million at Sotheby’s in New York. The fossil, which is described as one of the world’s most complete T. rex specimens, consists of 183 fossilized bones and is reported to measure about 12.5 feet tall and roughly 38 feet long. Sources say it was discovered on a cattle ranch in South Dakota in 2021. Coverage also notes that the sale draws significant competition, with bidding involving multiple participants and described as lasting about 10 minutes before a winner was secured. Several outlets report that the final price surpasses the pre-sale estimate and sets a new auction record specifically for a dinosaur fossil. Scientific American and other outlets characterize the transaction as making “Gus” the most expensive dinosaur sold at auction. The buyer is not identified in the provided reports. Overall, all sources agree on the fossil’s nickname, its high completeness, its discovery in South Dakota in 2021, and the final record-breaking price at Sotheby’s.
