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 ...
Stygivenator molnari. (Paul, 1988a emend Paul, 1990) Olshevsky, 1995. Tyrannosaurus ( / tɪˌrænəˈsɔːrəs, taɪ -/) [a] is a genus of large theropod dinosaur. The type species Tyrannosaurus rex ( rex meaning "king" in Latin ), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
The largest species was Tyrannosaurus rex, the most massive known terrestrial predator, which measured over 13 metres (43 ft) in length and according to most modern estimates up to 8.87 metric tons (9.78 short tons) in weight. Tyrannosaurids were bipedal carnivores with massive skulls filled with large teeth. Despite their large size, their ...
June 4, 2024 at 7:40 AM. By Will Dunham. (Reuters) - A rare fossil of an adolescent Tyrannosaurus rex has been excavated in North Dakota's badlands - a find noteworthy for the scientific insight ...
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 ...
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.
Alioramus ( / ˌælioʊˈreɪməs /; meaning 'different branch') is a genus of tyrannosaurid theropod dinosaurs from the Late Cretaceous period of Asia. It currently contains two species. The type species, A. remotus is known from a partial skull and three foot bones recovered from the Mongolian Nemegt Formation, which was deposited in a humid ...
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.
