A 67 million-year-old Tyrannosaurus rex specimen nicknamed Stan has just shattered a record; on Monday (Oct. 6), Stan was sold at Christie’s New York for nearly $32 million. That makes it the most expensive fossil ever sold at an auction.
Previously, the priciest fossil to hit the auction block was an incredibly complete T. rex known as Sue, which sold for $8.36 million in 1997 ($13.5 million in today’s dollars, given inflation) to the Field Museum of Natural History in Chicago. Meanwhile, the buyer of Stan has not been identified, according to The New York Times.
Many paleontologists are dismayed that Stan sold for so much to an unknown buyer, especially now that many scientific institutions don’t have the money to purchase such fossils and keep them in the public domain. However, unlike other dinosaur specimens, Stan had no choice but to go to the auction block, so how did it end up there?

Normally, the Society of Vertebrate Paleontology (SVP) opposes the auction of such fossils. In 2018, for instance, SVP asked the Aguttes auction house in Paris to pull the plug on auctioning off an Allosaurus, a type of meat-eating dinosaur, that had been found on private land in Wyoming. In contrast, Stan came to the auction house not because its owner wanted to turn a profit, but through a court order, which complicated SVP’s response.
Amateur paleontologist Stan Sacrison found Stan in 1987 in the Hell Creek Formation, near the town of Buffalo, South Dakota, according to the Black Hill Institute of Geological Research (BHI), a company that supplies fossils for research, teaching and exhibit. After learning about the specimen, BHI scientists spent more than 300,000 hours excavating and preparing the nearly 40-foot-long (12 meters)
