One of the most complete Tyrannosaurus rex specimens ever found, nicknamed "Gus," sold at Sotheby's on July 14 for $50.1 million to an unidentified buyer, setting a record for the most valuable fossil ever auctioned. The specimen was excavated from the Hell Creek Formation in South Dakota over three years starting in 2021 by commercial collector Thomas Heitkamp and his team.

The sale has renewed concern among paleontologists. A 2025 study found 61 T. rex fossils in public trusts compared with 71 held privately. The Society of Vertebrate Paleontology, whose president-elect authored the Live Science commentary, argues that scientifically significant vertebrate fossils belong in the public trust where they can be permanently preserved, made available for research, and shared with the public.

Proponents of commercial fossil sales contend that without private buyers, specimens like Gus would remain buried or erode away. Once a fossil enters a private collection, however, researcher access is not guaranteed; owners can revoke loan agreements at any time, and specimens housed in homes lack the curatorial standards of museums and universities.
