A Tyrannosaurus rex excavated on private land in Harding County, South Dakota, brought a record-breaking $50.1 million at a Sotheby’s auction in New York on July 14. The specimen, nicknamed “Gus,” is being described by the auction house as one of the largest and most complete T. rex fossils ever offered publicly.
What was sold
Standing mounted with its tail extended and one foot slightly raised, the adult T. rex measures roughly 3.8 meters (about 12 1/2 feet) tall and 11.5 meters (about 38 feet) long. Sotheby’s says the fossil is approximately 61% complete, with an exceptionally well-preserved skull and a set of rare bones including a furcula, or wishbone. The skeleton was recovered beginning in 2021 from a ranch owned by Gary and Dana Licking.
“Gus is not only an exceptional find, but a specimen that’s been excavated, documented, prepared, and cared for with real excellence,” Sotheby’s vice chair Cassandra Hatton said after the sale.
The 10-minute bidding contest, conducted both live and online, ended with an anonymous telephone bidder outbidding six other prospective buyers. Sotheby’s had estimated the specimen would fetch between $20 million and $30 million.
Local roots, national spotlight
Harding County sits within the Hell Creek Formation, a stretch of terrain across parts of South Dakota, Montana, North Dakota and Wyoming known for yielding high-profile dinosaur discoveries. The region has produced other headline-making finds — including the famous T. rex “Sue” in the 1990s — and this sale spotlights how fossils from rural South Dakota can become objects of intense international interest.
- Discovery: Excavation began in 2021 on private land in Harding County.
- Completeness: Approximately 61% of the skeleton.
- Sale price: $50.1 million, a new auction record for dinosaur fossils.
- Buyer: Anonymous phone bidder.
Scientific and public access concerns
The sale revived a familiar debate among paleontologists and museum advocates: whether scientifically important fossils should end up in private hands or be kept in public institutions for study and display. The Society of Vertebrate Paleontology has argued that specimens of this caliber belong on public display where scientists and the public can access them.
“The market responds when great specimens are taken care of in the right way,” Hatton said, praising the excavation and preparation. Auctioneer Phyllis Kao later encouraged bidders by reminding them, “It’s a T. rex, after all.”
Researchers involved in the excavation noted the specimen shows signs of injuries and scars that could provide a snapshot of life and behavior, although the new owner’s plans for the fossil — whether it will be displayed publicly or remain in private hands — were not disclosed.

For communities in western South Dakota, such sales underscore both the value of local paleontological resources and the tension between private landownership, the commercial market for fossils, and scientific stewardship. Previous high-profile fossil sales have prompted legal disputes and long negotiations over where specimens should live and who controls research access.
As of the sale, the buyer has chosen to remain anonymous. That leaves open whether the specimen will eventually be loaned or donated to a museum, studied by academic teams, or kept in a private collection. For now, a fossil excavated from a sparsely populated corner of South Dakota has set a new benchmark in the market for prehistoric remains, drawing fresh attention to the region’s fossil-rich soils and the questions they raise about preservation and public benefit.
