A Tyrannosaurus rex skeleton known as Gus was sold for $50.1 million at Sotheby's in New York, making it the most expensive fossil ever auctioned. The sale followed a fierce ten-minute bidding war among seven buyers, far exceeding the expected $20 to $30 million range.12
Gus, measuring 38 feet long and 12.5 feet tall, is one of the most complete T. rex skeletons, comprising 183 fossil bone elements and preserving 61% of the original skeleton by bone count. Its well-preserved features include a 54-inch skull, a wishbone, and both feet, making it exceptionally rare among T. rex discoveries.4
Excavated from the Hell Creek Formation in South Dakota in 2021, Gus's bones reveal a history of survival, with marks from ancient bites and healed fractures. The identity of the anonymous buyer remains undisclosed, raising concerns about whether Gus will be displayed publicly or kept in a private collection.7
Cassandra Hatton, head of science and natural history at Sotheby's, noted, “The United States is the only country in the world where fossils like this are considered personal property.” The auction reflects a growing trend among wealthy collectors, igniting debates over the accessibility of scientifically significant fossils.
The previous record was held by a Stegosaurus fossil named Apex, which sold for $44.6 million in 2024. The sale of Gus underscores the increasing commercialization of dinosaur fossils, with some collectors viewing them as art or collectibles.
“The 38-foot-long, 67-million-year-old skeleton is 61% complete by bone count and features a remarkably preserved skull with bite marks and healed fractures hinting at a violent life. The previous record of $44.6 million was set by a Stegosaurus fossil in 2024, and the sale has renewed debate over whether such scientifically important fossils should remain in public hands.”
