Tyrannosaurus was a bulky and heavy carnivore so it is unlikely to run very fast at all compared to other theropods like Carnotaurus or Giganotosaurus. [169] Researchers have relied on various estimating techniques because, while there are many tracks of large theropods walking, none showed evidence of running. [170]
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.

These proportions persist even in the largest adult Tyrannosaurus, [11] despite its probable inability to run. [12] The third metatarsal of tyrannosaurids was pinched at the top between the second and fourth, forming a structure known as the arctometatarsus. [1]
Using a steel Tyrannosaurus rex skull, scientists learned that Tyrannosaurus could easily crush a small mini cooper. Scientists learn that Tyrannosaurus could run at 25 miles per hour; Scanning an endo cast from a Tyrannosaurus rex skull, scientists theorize that Tyrannosaurus rex had a brain similar to that of a modern-day alligator.
Valley of the T. rex is a Discovery Channel documentary, featuring paleontologist Jack Horner, that aired on September 10, 2001.The program shows Horner with his digging team as they travel to Hell Creek Formation in search for dinosaur fossils, while also following Horner as he presents his view of the theropod dinosaur Tyrannosaurus rex as a scavenger rather than a predator, as it is often ...
Skeletal mount of the Tyrannosaurus holotype.. This timeline of tyrannosaur research is a chronological listing of events in the history of paleontology focused on the tyrannosaurs, a group of predatory theropod dinosaurs that began as small, long-armed bird-like creatures with elaborate cranial ornamentation but achieved apex predator status during the Late Cretaceous as their arms shrank and ...

Tyrannosaurus, however, had a hard palate, just like mammals and crocodiles. [7] Holtz along with James O. Farlow would also support freelance researcher Gregory S. Paul's suggestion that Tyrannosaurus could have used hit-and-run attacks on its prey. [15] [59] Denversaurus and the "Wyrex" specimen, Houston Museum of Natural Science
