Sotheby’s to auction T. rex skeleton ‘Gus’ for up to $30M

T. Rex Fossil “Gus” Heads to Sotheby’s With $20–$30 Million Estimate

Sotheby’s announced on Wednesday that it will auction a Tyrannosaurus rex skeleton named “Gus” as the centerpiece of its annual Geek Week sales this July, carrying an estimate of $20 million to $30 million — the highest pre-sale estimate ever placed on a dinosaur fossil at auction.artnet

A Monster Specimen

The 67-million-year-old skeleton stands over 12 feet tall and stretches nearly 38 feet from nose to tail, preserving 183 fossil bone elements. According to Sotheby’s, the specimen includes an exceptionally rare set of gastralia, or “belly ribs,” rarely seen mounted together. The fossil also bears fossilized traces of a violent prehistoric life: healed fractures, bite marks to the skull and body, and evidence of ancient combat or scavenging still visible after millions of years.sothebys

Gus will be exhibited for the first time at Sotheby’s Breuer building in New York, on free public view from July 1 through 14 ahead of the sale. The specimen will headline Geek Week 2026 alongside rare meteorites, space exploration artifacts, and vintage technology including a celebrated Apple-1 computer.instagram

A Booming Market for Dinosaurs

The auction arrives amid a sustained surge in prices for prehistoric specimens. The current record for a fossil sold at auction stands at $44.6 million, paid by hedge fund billionaire Kenneth Griffin for “Apex,” a stegosaurus, at Sotheby’s in July 2024. Last July, a juvenile Ceratosaurus — one of only four known to exist — sold at Sotheby’s for $30.5 million, more than five times its pre-sale estimate of $4 million to $6 million. The T. rex known as “Stan” sold at Christie’s in 2020 for $31.8 million, then the record for a dinosaur fossil.nytimes

If Gus reaches its high estimate or beyond, it could challenge some of those benchmarks and would represent the most expensive T. rex ever sold at auction.

Controversy and Context

The private sale of major fossils has drawn criticism from paleontologists who argue that commercially driven excavation removes specimens from scientific study. The cancellation of the “Shen” T. rex auction in Hong Kong in 2022, pulled over intellectual property disputes regarding replica bones, highlighted the complex provenance issues that can surround such sales.youtube

Sotheby’s described Gus as among the finest T. rex specimens in private hands, positioning it as an “exhibition-ready” skeleton suited for institutional or private display.sothebys
