A 10-Minute Bidding War Ends with a $50.1 Million T. Rex

The room at Sotheby's New York erupted in applause. After a ten-minute battle between seven bidders on phones, online, and in the room, the hammer fell. The final price for a Tyrannosaurus Rex skeleton named Gus was over $50.1 million.

The sale makes Gus the most expensive dinosaur ever sold at auction. The result more than doubled the low-end of its $20-30 million estimate, setting a new benchmark for natural history as a collectible asset.

Five Years in the Making

The journey to the auction block was a long one. The specimen was first excavated in Harding County, South Dakota, from the Hell Creek Formation, a layer of earth dating to the Late Cretaceous period. It took five years to prepare the 67-million-year-old skeleton for this moment.

Officially, Gus is the largest and most complete T. Rex ever sold. Its scale and condition were key factors in the intense interest from collectors around the world.

Surpassing the Apex Predator

The sale at Sotheby's surpasses a recent high-water mark set in 2024. That year, a Stegosaurus fossil known as ‘Apex’ achieved a price of $44.6 million, establishing a new record at the time.

With a final price of over $50.1 million, the sale of Gus confirms a rapidly escalating market for world-class natural artifacts. What was once the domain of museums is now a fixture of the world’s most significant private collections.
