The Auction Outcome
On 14 July 2026, Sotheby’s in New York auctioned lot 20—a mounted Tyrannosaurus rex skeleton nicknamed Gus—to an anonymous phone bidder for a hammer price of $50.1 million (? £37.4 million). The ten-minute bidding war involved seven participants, far exceeding the pre-sale estimate of $20 million–$30 million. The sale set a new world record for any dinosaur fossil, surpassing the previous high of $44.6 million for the stegosaurus Apex sold in 2024.
Market Context and Precedents
The transaction reflects a rapid escalation in the commercial fossil market. Earlier record-holders include the T. rex Stan (? $31.8 million, 2020) and the iconic Sue (sold in 1997). Auction houses now list dinosaur specimens alongside fine art, a trend that has drawn both enthusiasm from collectors and alarm from scientists. In the United States, fossils discovered on private land are legally considered personal property, allowing owners to sell them at market rates.
Principal Actors
- Gary “Gus” Licking – former ranch owner in Harding County, South Dakota, after whom the specimen is named.
- Thomas Heitkamp – paleontologist with Theropoda Expeditions, led the three-year excavation (2021-2023).
- Cassandra Hatton – Sotheby’s vice-chairman and worldwide head of science and natural history, spokesperson for the house.
- Phyllis Kao – auctioneer who conducted the live sale.
- Kristi Curry Rogers – president-elect of the Society of Vertebrate Paleontology (SVP).
- Richard Butler – vertebrate paleontologist, University of Birmingham, vocal critic of high-price fossil sales.
- Anonymous buyer – the winning participant, whose identity and intended use for the fossil remain undisclosed.

- Bidding details: 7 bidders, 10-minute battle, final price $50.1 million plus fees.
Why It Matters
The sale underscores a booming niche where ultra-wealthy collectors treat rare fossils as investment assets. Proponents argue that commercial excavation rescues specimens that might otherwise remain buried, while opponents warn that private ownership can lock scientifically vital material out of public research, limiting reproducibility and long-term study.
Official Statements & Responses
Sotheby’s highlighted the specimen’s scientific merit, noting that “Gus is an exceptional find, excavated, documented, prepared and cared for with real excellence.” The house also emphasized that the market rewards meticulous preparation. The SVP issued a statement urging the new owner to donate the fossil to an accredited museum, stressing that public stewardship ensures preservation, documentation, and accessibility for future generations. Auctioneer Phyllis Kao added a light-hearted reminder during the sale, urging bidders to “Try a bigger bite.”
Criticism & Opposition
Paleontologists expressed deep concern. Richard Butler described the trend of marketing fossils “like rare artworks at vast prices” as “very concerning,” warning that specimens outside museum collections are effectively lost to research. Stephen Brusatte echoed the sentiment, noting that while the sale is legal under U.S. property law, it “still concerns” scientists. The SVP reiterated that fossils of this significance belong in public institutions to safeguard scientific progress.
Conflicting Reports & Gaps
Sources differ on completeness percentages (61 % vs. 63 % by bone count) and on the exact total price (some cite $50.1 million, others $50.13 million including fees). The identity and future plans of the buyer remain undisclosed, leaving open the question of whether the specimen will be displayed publicly or remain in a private collection.
