The world's most expensive dinosaur fossil has been sold at auction, fetching a staggering $50.1 million at Sotheby's. The Tyrannosaurus rex skeleton, nicknamed "Gus," surpassed its estimated price of $20 million to $30 million after a 10-minute bidding war involving seven bidders.
Gus is one of the largest and most complete T. rex specimens ever discovered, standing at 12½ feet tall and stretching roughly 38 feet. The skeleton includes 183 fossil bone elements, making it about 61% complete by bone count and representing an estimated 75% to 80% of the dinosaur's original bone mass.
The record-breaking sale began on a cattle ranch in Harding County, South Dakota, where ranch owner Gary "Gus" Licking had spent years finding teeth and small bone fragments before partnering with Thomas Heitkamp and his team from Theropoda Expeditions to search for something larger. The team spent three field seasons excavating the fossil before years of lab work cleaning, documenting, and assembling the skeleton.
The discovery of Gus required years of persistence and dedication, as Heitkamp noted, "This specimen took three years to excavate. In the end, our diligence paid off, and we were delighted to discover what turned out to be a huge and incredibly complete T. rex specimen."
The sale of Gus has renewed a long-running debate over whether rare dinosaur fossils belong in private collections or public museums. The Society of Vertebrate Paleontology hopes the new owner chooses to make it accessible to the public, stating that specimens like Gus are best preserved in museums, where they can remain available for scientific research and public education.
