Stan, who lived in the private Black Hills Institute of Geological Research in South Dakota, was auctioned off by Christie’s in October 2022 for a record USD 31.8 million, the highest price ever paid at any auction for a fossil. However, the name of the buyer was never disclosed. Although Stan is believed to be the most duplicated T. rex fossil, its plaster casts showcased in many museums around the globe, scientists feared that studies performed on the original would be hampered if the unknown owner and his or her intention was not clear. Hope flickered when a similar dinosaur head was caught on camera while a television channel was interviewing Dwayne "The Rock" Johnson (actor, former wrestler and sports commentator), according to media reports. However, soon Dwayne himself put the controversy to rest declaring that the head was a cast and not the real one.
