• The auction featured a bidding war among seven participants lasting just 10 minutes.

A Tyrannosaurus rex skeleton, affectionately named “Gus,” fetched a staggering $50.1 million at a Sotheby’s auction in New York, marking the highest price ever paid for a dinosaur fossil. The sale followed a brief 10-minute competitive bidding session involving seven bidders, showcasing a lucrative market for paleontological specimens. “Gus,” standing at approximately 12.5 feet tall and over 38 feet long, comprises 183 fossilized bones and is considered one of the most complete T. rex skeletons discovered to date, according to CBS News and BBC.

Discovered on a ranch in South Dakota in 2021, “Gus” dates back approximately 67 million years to the late Cretaceous period. Sotheby’s representatives highlighted the meticulous work involved in excavating and preparing the skeleton, stating it underwent three summers of excavation and an additional three years in a laboratory. Notably, the fossil includes evidence of past injuries, such as bite marks and healed ribs, identifying instances of conflict or scavenging during its life, according to South China Morning Post and BBC.

The auction's outcome reflects a rising trend in fossil collecting, which has garnered concern among certain palaeontologists about the ethical implications of private ownership of significant scientific specimens. Cassandra Hatton of Sotheby’s remarked on the unique U.S. policy allowing landowners to sell fossils found on their property, stating, “If you own the land, you own the fossil and you have the right to sell it,” a sentiment echoed by South China Morning Post.
