A giant Tyrannosaurus rex known as Gus has rewritten the record books after selling for an astonishing US$50.1 million at a Sotheby’s auction in New York. The result makes the prehistoric predator the most expensive dinosaur fossil ever sold at auction.
The sale attracted intense interest, with seven bidders competing over roughly 10 minutes before an anonymous buyer secured the fossil. Auction organisers had estimated the skeleton would fetch between US$20 million and US$30 million, making the final result well above expectations.
Named after ranch owner Gary “Gus” Licking, the dinosaur was discovered on private land in South Dakota. Excavation work began in 2021 and continued over several years, ultimately revealing one of the largest and most complete T-rex specimens ever uncovered.
Standing around 3.8 metres tall and stretching about 11.5 metres long, Gus is estimated to be 67 million years old. The specimen contains 183 fossil bone elements and is around 61 per cent complete by bone count, with an exceptionally preserved skull among its standout features.
The previous auction record for a dinosaur fossil was set in 2024 when a stegosaurus nicknamed Apex sold for US$44.6 million. Before that, a T-rex called Stan held the record after fetching nearly US$32 million in 2020. The sale of Gus shows that interest in high-profile dinosaur specimens continues to grow among wealthy collectors.
Not everyone is celebrating the result. Some palaeontologists have previously expressed concerns that important fossils entering private collections can become less accessible for scientific research and public education. The record-breaking sale has reignited debate about the balance between private ownership and preserving important specimens for study.
