The holotype of Tyrannosaurus rex, a partial skull and skeleton originally called AMNH 973 (AMNH stands for American Museum of Natural History), was discovered in the U.S. state of Montana in 1902 and excavated over the next three years.

Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits.

(The longest known T. rex skull is “ Maximus,” an exceptional specimen spanning 2 meters [6.6 feet] long). The skull bones of large specimens are often several centimeters thick and are strongly braced to each other, which suggests a resistance to the forces of biting, both inflicted upon and received from other tyrannosaurs.

The first skeleton of Tyrannosaurus rex was discovered in 1902 in Hell Creek, Montana, by the Museum's famous fossil hunter Barnum Brown. Six years later, Brown discovered a nearly complete T. rex skeleton at Big Dry Creek, Montana.

Feb 3, 2025 · Most were large predators, with very large skulls approaching or well exceeding a full meter (more than three feet) in length. The best-known and largest member of the group is Tyrannosaurus rex, or T. rex.

Feb 5, 2018 · At more than 40 feet long and 13 feet tall at the hip, SUE is physically the largest Tyrannosaurus rex specimen discovered, out of more than 30 T. rex skeletons that have been found. SUE is also the most complete—around 90 percent.

The Burke Museum’s paleontology team continues to make exciting progress preparing the "Tufts-Love" T. rex skull —one of around 15 Tyrannosaurus rex skulls known to exist in the world. The team has now found 100% of the dinosaur’s skull and jaw bones by bone count.

Weighing up to eight tons, T. rex stomped headfirst across its territory on two strong legs. These dinosaurs likely preyed on living animals and scavenged carcasses —and sometimes they …

Aug 18, 2016 · Paleontologists with the University of Washington’s Burke Museum of Natural History and Culture have discovered a Tyrannosaurus rex, including a very complete skull. The find, which paleontologists estimate to be about 20 percent of the animal, includes vertebrae, ribs, hips and lower jaw bones.
