Imagine spending more than fifty million dollars at an auction and staying completely anonymous. That’s the question surrounding ‘Gus’ – an almost complete skeleton of a tyrannosaurus rex that was sold by Sotheby’s Auction House in July to a mystery phone bidder for 50.1 million dollars.
The sale is the most expensive fossil ever sold. ‘Gus’ is different because it’s about 80 percent complete by mass and still has its feet, pelvis and wishbone fully intact unlike most other t-rex fossils. It’s also sixty-seven million years old and was uncovered in South Dakota back in 2021. Fully intact fossils like this are so important because it can help humans learn more about how dinosaurs grew, moved and lived.
From a sale perspective, a private auction doesn’t automatically mean an important object will disappear forever. Some buyers eventually loan their purchases to museums. For example, the stegosaurus known as “apex,” which sold for almost 45 million dollars in 2024, is now on display at the American Museum of Natural History in New York.
The difference is that the decision rests fully with the owner. Until they come forward, researchers may not know where a fossil is being stored, whether they can examine it or if the public will ever see it. The same concern comes up when anonymous collectors buy rare paintings, historical documents or cultural artifacts. Sometimes these objects end up in museums, and other times, they move into private homes or storage facilities and aren’t seen again for many years.
One possible compromise is to require stronger agreements before one-of-a-kind objects are sold at auction. Companies like Sotheby’s could ask buyers to allow research access or place the item on public loan for part of each year.
At the end of the day, science and museums rely on private money to protect these pieces long-term, however the question is whether ownership should also come with some responsibility to keep them available to scientists and the public.
