"Stan", also known by its inventory number 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.

[4] In March 2022, Abu Dhabi's Department of Culture and Tourism stated that they had acquired Stan and were planning on displaying the fossil at a new museum of natural history scheduled to open in 2025.

[12] The bones of Stan the T. rex were cleaned and prepared at the Black Hills Institute where resident paleontologists and paleobotanists continued to study him and the fossilized plants he was discovered with.

[10][8] Stan's fossils show notable signs of wear and indication that the dinosaur experienced multiple attacks and illnesses throughout his life.

[2] Other bite marks at the base of his skull suggest his neck was once broken and caused the fusion of two vertebrate, resulting in a loss of mobility and pain for the rest of his life.

Other irregularities in Stan's skull include non-symmetrical holes on either side of his jaw with smoothed edges, which are indications that these are more healed wounds.

[10][3] It is unknown what exactly caused Stan's death, but many theories suggest that it could have been the result of old age, starvation due to limited mobility from his injuries, or even parasitic infections that many T. rex exhibit signs of.

[14] In 2005, the BBC program The Truth About Killer Dinosaurs used Stan's skull as a model for their hydraulic test of the T. rex's bite force and estimated that it exceeded 6.8 tonnes.

Additional tests, like those published by Karl T. Bates and colleagues in 2009, used Stan's remains to study the weight distribution of T.rex, as well as how their mass and proportions would have affected their movement.

[22] During a Manningcast broadcast of a National Football League playoff game on January 17, 2022, Dwayne "The Rock" Johnson was interviewed by Peyton and Eli Manning while at his home.
