At Sotheby's in New York, a Tyrannosaurus rex skeleton known as Gus crossed the auction block for $50.1 million — the highest price ever paid for a paleontological specimen — vanishing into the hands of an anonymous buyer. The sale is not merely a record-breaking transaction but a marker of a deepening divide between private wealth and public knowledge, where the relics of deep time increasingly become trophies rather than teachers. What is lost when the past belongs only to those who can afford it is a question science may one day be unable to answer.
