The fossil of a Tyrannosaurus rex, known as one of the largest and most complete specimens, has set a new auction record. The 67-million-year-old remains, nicknamed ‘Gus,’ were sold by Sotheby’s for $50.1 million.
The auction took place on Tuesday, marking the fossil as the most expensive dinosaur bones ever sold. This surpasses the previous record held by a stegosaurus fossil sold by Sotheby’s in 2024 for nearly $45 million. Prior to this, a T. rex skeleton named ‘Stan’ sold for almost $32 million in 2020.

Unique Characteristics of ‘Gus’
‘Gus’ stands upright with a tail and raised right foot. This adult dinosaur measures about 12.5 feet tall and 38 feet long, with a 63% completion rate. The fossil boasts an exceptionally preserved skull, including a jaw full of powerful teeth and two well-represented feet. It also contains several rare bones, such as a wishbone.
Discovered in 2021 on a South Dakota ranch, the fossil was named after Gary Licking, the property owner who passed away during the excavation and restoration process.
Auction Details
The fossil attracted intense bidding, with seven prospective buyers. A 10-minute bidding session concluded with a mystery buyer winning the auction. The final sale exceeded the estimated value of $20 to $30 million.
Auctioneer Phyllis Kao humorously urged bidders to make higher offers, highlighting the value of owning a T. rex fossil. Despite inquiries, the buyer’s identity and intentions remain unknown.
Public Display and Scientific Preservation
The Society of Vertebrate Paleontology advocates for the public display of significant fossils like ‘Gus’ in museums for scientific study and preservation. Kristina Curry Rogers outlined the potential for new scientific discoveries as technologies evolve.
For reference, previous fossil record-holders, such as ‘Apex’ the stegosaurus, and other T. rex fossils like ‘Sue,’ are displayed in reputable museums. ‘Stan’ is showcased at the Natural History Museum in Abu Dhabi.
T. rex: A Cretaceous Icon
The Tyrannosaurus rex, meaning ‘King of the Tyrant Lizards,’ ruled as a top predator during the late Cretaceous period. Its iconic appearance, with a large, fearsome jaw and small arms, has captivated popular culture through children’s shows and films like ‘Jurassic Park.’
These giants dominated what is now western North America, thriving in environments rich with herbivorous prey, such as the triceratops.
