Quick—think of a dinosaur! Did Tyrannosaurus rex come to mind? With its massive teeth, tiny arms, and reputation as a fierce killer, this apex predator is one of the most famous prehistoric creatures to walk the earth. Now imagine you own a T. rex skeleton. What would you do with it?
This seems like a ridiculous question, but it’s a real one for a collector who purchased one of the largest T. rex skeletons ever found—named Gus—at an auction in July 2026. In an auction, multiple people place bids, competing to buy an item, and the highest bidder wins. In this case, a mystery buyer purchased Gus for a whopping $50.1 million! This makes Gus the most expensive dinosaur fossil ever sold.
