Sotheby's to auction T rex skeleton Gus for millions

The auction house will offer a Tyrannosaurus rex skeleton known as Gus during its annual Geek Week sale in July, with estimates ranging between 20 million and 30 million dollars. The specimen is presented as one of the most significant prehistoric fossils ever brought to the commercial market, reflecting strong demand for large dinosaur skeletons among private collectors and institutions.

Gus dates back around 67 million years and measures more than 3.6 meters in height and about 11.6 meters in length from snout to tail. The skeleton includes 183 fossilized bone elements, making it one of the more complete Tyrannosaurus rex specimens available. It also preserves rare gastralia, or belly ribs, a feature seldom displayed in assembled fossil skeletons.

The fossil shows multiple signs of ancient trauma. These include healed fractures, bite marks on the skull and body, and other damage consistent with predatory encounters or scavenging. Such features add scientific interest, as they provide direct evidence of behavior and survival dynamics in the late Cretaceous period.

Before the sale, Gus will be exhibited in New York from July 1 to July 14, where the public will be able to view it. The skeleton will headline a broader collection of objects linked to space exploration, meteorites, and vintage technology, positioning the fossil within a curated high-value collectible event.

The market for dinosaur fossils has seen rapid price increases in recent years. A stegosaurus specimen previously set a record at 44.6 million dollars, while other major dinosaur sales have reached more than 30 million dollars, including a ceratosaurus and a tyrannosaurus known as Stan. Gus enters this competitive market with the potential to challenge existing records if bidding exceeds expectations.

Critics in the scientific community have raised concerns about the privatization of important fossils, arguing that commercial sales can limit access for research. Despite this debate, auction houses continue to frame such specimens as both investment-grade assets and display pieces suitable for museums or private collections.
