Want to own a real T. rex? It could cost you $30 million

NPR reports that a Tyrannosaurus rex fossil nicknamed "Gus"—a 67-million-year-old specimen discovered in 2021 on a South Dakota ranch—will be auctioned at Sotheby's in New York with a pre-sale estimate of $20–$30 million, potentially becoming the most expensive dinosaur fossil ever sold. The article is bylined by Chandelis Duster and sourced from NPR, a major national outlet with strong editorial standards, though the metadata provided does not include specific named sources or detailed reporting on the specimen's significance or the auction mechanics. Multiple independent outlets (BBC, The Times of India, South Dakota News Watch) corroborate the auction date (July 14), the specimen's discovery timeline, and the price estimate, adding context that this could set a new record for dinosaur fossil sales and noting prior sales of dinosaur bones to private collectors. Readers should monitor the actual auction results and any post-sale reporting on who acquired the fossil and whether the estimate was exceeded, as well as any broader implications for the market for paleontological specimens.
