In a groundbreaking auction, a Tyrannosaurus rex fossil known as ‘Gus’ sold for an unprecedented $50.1 million at Sotheby’s in New York. This 67-million-year-old relic, among the largest and most complete T. rex specimens, has become the priciest dinosaur bones auctioned, surpassing the sale of a nearly complete stegosaurus sold for almost $45 million in 2024.
‘Gus’ has eclipsed the previous record holder, a T. rex named ‘Stan’ that fetched nearly $32 million in 2020. According to Cassandra Hatton, Sotheby’s vice chair, ‘Gus’ is a remarkable find, meticulously excavated and preserved, which contributed to the intense market interest during the sale.
Details of the T. Rex Fossil
‘Gus’ is an adult Tyrannosaurus rex standing approximately 12 ½ feet tall and 38 feet long. The skeleton is around 63% complete, featuring an impressively preserved skull with powerful teeth, two well-represented feet, and rare bones like the furcula.
Found in South Dakota in 2021, the fossil was named for Gary Licking, the property owner who passed away during its excavation and restoration process. The intense bidding battle lasted 10 minutes, with an undisclosed winner competing against six others. The sale exceeded initial estimates of $20 to $30 million.
Scientific Community’s Desire for Public Display
The Society of Vertebrate Paleontology expressed a desire for ‘Gus’ to be accessible to the public. The organization believes that important fossils should be housed in museums for preservation and future research. Kristina Curry Rogers emphasized that significant scientific advancements can occur years after a fossil is collected due to evolving research methods.
Examples of fossil accessibility include ‘Apex,’ a stegosaurus on loan to the American Museum of Natural History, and ‘Sue,’ a centerpiece at the Field Museum in Chicago. ‘Stan’ is also displayed at the Natural History Museum Abu Dhabi.
Tyrannosaurus Rex: A Legendary Predator
The Tyrannosaurus rex, meaning ‘King of the Tyrant Lizards,’ was a dominant predator in the late Cretaceous period, recognized by its formidable jaws and small arms. This dinosaur has remained a cultural icon, appearing in children’s shows and the ‘Jurassic Park’ film series.
These predators thrived in what is now western North America, a region abundant with rich ecosystems and large herbivores like triceratops, as described by Sotheby’s.
