Overview
- A Tyrannosaurus rex skeleton nicknamed “Gus” sold at Sotheby’s for $50.1 million to an anonymous phone bidder, a result reached on July 14, 2026 that set a new auction record for a fossil.
- The specimen was found on private land in South Dakota and excavated by commercial teams beginning in 2021; the mounted skeleton includes 183 bones and is roughly 61 percent complete by bone count.
- Paleontologists and the Society of Vertebrate Paleontology warned that private ownership can make scientifically significant fossils effectively inaccessible and undermine the ability to verify and revisit research.
- Museum leaders say public institutions often cannot match private prices, and although some high‑profile purchases have later been donated to museums, rising auction values make public acquisition less reliable.
- Because fossils from the Hell Creek Formation provide context used by modern techniques like CT scanning and isotope analysis, the sale raises the risk that future discoveries and tests on this T. rex could be limited if the new owner keeps it private.
