"Stan" (NHMAD 2020.00001, formerly BHI 3033) is a Tyrannosaurus rex fossil found in the Hell Creek Formation in South Dakota, just outside of Buffalo in 1987, and excavated in 1992. It is the fifth most complete T. rex fossil discovered to date, at more than 70% bulk. In October 2020, the fossil was sold for $31.8 million at auction, making it at the time the most expensive dinosaur specimen and fossil ever sold. This record stood until July 2024, when the Stegosaurus fossil Apex sold at auction for $44.6 million. The Abu Dhabi Department of Culture and Tourism acquired Stan and displayed the fossil at the Natural History Museum Abu Dhabi which opened on November 22, 2025.
