Nonetheless, Tyrannosaurus was probably able to get up if it fell, which only would have required placing the limbs below the center of gravity, with the tail as an effective counterbalance. Healed stress fractures in the forelimbs have been put forward both as evidence that the arms cannot have been very useful [ 142 ] [ 143 ] and as evidence ...
The autopodium itself is subdivided into three segments: the carpalia (forelimb) or tarsalia (hind limb) form the basipodium; the metacarpalia (forelimb) or metatarsalia (hind limb) the metapodium; and the phalanges of the digits the acropodium. [70]: 18 An aberrant terminology was proposed by Günter Wagner and Chi-Hua Chiu in 2001.
Archived pictures show the original skeleton from Egypt, including parts of the dinosaur’s skull, spine and hind limbs before its destruction. “What we saw in the historical images surprised ...
Dinosaurs stand with their hind limbs erect in a manner similar to most modern mammals, but distinct from most other reptiles, whose limbs sprawl out to either side. [35] This posture is due to the development of a laterally facing recess in the pelvis (usually an open socket) and a corresponding inwardly facing distinct head on the femur. [36]
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. [126]
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 ...

The forearms of Tyrannosaurus were not well documented and the hands were unknown, so for the sake of the display, the forearms of AMNH 5027 were given three fingers, based on the forelimbs of Allosaurus (the more allosaur-like arms were replaced several years later when better fossils of tyrannosaurid arms were found).
