With a length of 12.1-12.2 meters, AMNH 5027 was discovered and excavated in 1908 by Barnum Brown in Montana, and described by Osborn in 1912 and 1916. At the time of discovery, a complete cervical (neck vertebrae) series for Tyrannosaurus was not

With the possible exception of Raptorex, [17] it is widely assumed that the Asian specimens are early growth stages of Tarbosaurus, [18] [19] [20] whereas the North American specimens are those of Tyrannosaurus.

From measurements and based on the positions of the footprints, the animal was believed to be traveling at a walking speed of around 2.8 to 5 miles per hour and was estimated to have a hip height of 1.56 to 2.06 m (5.1 to 6.8 ft). [25] [26] [27] A follow-up paper appeared in 2017, increasing the speed estimations by 50–80%. [28]
The debate about whether Tyrannosaurus was a predator or a pure scavenger is as old as the debate about its locomotion. Lambe (1917) described a good skeleton of Tyrannosaurus ' s close relative Gorgosaurus and concluded that it and therefore also Tyrannosaurus was a pure scavenger, because the Gorgosaurus ' s teeth showed hardly any wear.

The model Tyrannosaurus was constructed of fiberglass and steel, with a height of 26.3 metres (86 ft) and a length of 46 metres (151 ft), [1] considerably larger than the largest known specimens of the actual dinosaur, known as Sue, which reached up to 12.8 m (42 ft) in length, [2] and up to 4 m (13 ft) tall at the hips.
