A Tyrannosaurus rex skeleton has achieved a new auction record after “Gus” sold for $50.1 million USD at Sotheby’s New York. The sale exceeded its pre-auction estimate of $20 million–$30 million USD, making it the most expensive dinosaur fossil ever sold at auction.
Named after South Dakota rancher Gary “Gus” Licking, the specimen dates back approximately 67 million years. Measuring around 38 feet (11.6 metres) in length, the skeleton preserves 183 fossil bones, making it one of the largest and most complete T-Rex specimens ever discovered.
Rare specimen exceeds estimate after competitive bidding
Excavated between 2021 and 2023, Gus is regarded as one of the best-preserved Tyrannosaurus rex skeletons to reach the auction market. Consequently, the fossil attracted significant international attention ahead of the sale.
Seven bidders competed for the specimen before an anonymous telephone buyer secured the winning bid. The final price surpassed the previous auction record for a dinosaur fossil, set in 2024 when the Stegosaurus known as Apex sold for $44.6 million USD.
Earlier, another celebrated Tyrannosaurus rex specimen, Stan, sold for $31.8 million USD in 2020, setting a then-landmark benchmark for natural history auctions.
Record sale renews debate over fossil ownership
However, the sale has also revived longstanding discussions within the paleontological community about the future of scientifically significant fossils.
As with previous high-profile fossil sales, the auction has sparked debate among paleontologists, who argue that scientifically important specimens should remain accessible to museums and researchers rather than private collectors.
The record-breaking sale highlights the growing demand for exceptional natural history specimens within the global art and collectibles market, while continuing to raise questions about balancing commercial value with scientific access and preservation.
