The feeding behaviour of Tyrannosaurus rex has been studied extensively. The well known attributes of T. rex (its jaws, legs and overall body design) are often interpreted to be indicative of either a predatory or scavenging lifestyle, and as such the biomechanics, feeding strategies and diet of Tyrannosaurus have been subject to much research ...
The feeding habits, physiology, and potential speed of Tyrannosaurus rex are a few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a third Tyrannosaurus species, while others maintain Tarbosaurus is a separate genus.
As a result, the study determined that the hadrosaur diet probably consisted of leaves, and lacked the bulkier items such as twigs or stems, which might have required a different chewing method and created different wear patterns. [2] However, Purnell said these conclusions were less secure than the more conclusive evidence regarding the motion ...
Physiology of dinosaurs. The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation. Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
Sue[a] (stylized: SUE) is the nickname given to FMNH PR 2081, which is one of the largest, [b] most extensive, and best preserved Tyrannosaurus rex specimens ever found, at over 90 percent recovered by bulk. [4] FMNH PR 2081 was discovered on August 12, 1990, [5] by American explorer and fossil collector Sue Hendrickson, and was named after her ...
The skeleton of Montana's T. rex includes a relatively complete skull with jaws, multiple vertebrae of the back and tail, a well preserved gastralium, and hipbone with complete ischium and pubis. The left hindleg is relatively complete with a 1.2-meter-long (3.9 ft) femur, missing only some toe bones.
A new study suggests Tyrannosaurus rex had giant, full gums and lips that covered much of their teeth — far different from the gnashing jaws we saw in Jurassic Park.
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 ...
