Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [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.
Tyrannosaurus was named by Henry Fairfield Osborn in 1905, along with the family Tyrannosauridae. [15] The name is derived from the Ancient Greek words τυραννος tyrannos ('tyrant') and σαυρος sauros ('lizard'). The superfamily name Tyrannosauroidea was first published in a 1964 paper by the British paleontologist Alick Walker. [16]
The other tyrannosaurids share so many characteristics with Tyrannosaurus that only small dromaeosaurs remain as feasible top predators. In this light, scavenger hypothesis adherents have suggested that the size and power of tyrannosaurs allowed them to steal kills from smaller predators. [131]
Mounted skeletons of different age groups, Los Angeles Natural History Museum. 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 ...
The group includes some of the largest (Tyrannosaurus) and smallest (Microraptor, Parvicursor) carnivorous dinosaurs ever discovered. Characteristics that distinguish coelurosaurs include: a sacrum (series of vertebrae that attach to the hips) longer than in other dinosaurs; a tail stiffened towards the tip; a bowed ulna (lower arm bone).
This multispecies Tyrannosaurus classification is, however, not widely accepted by most paleontologists. [36] In some phylogenetic studies Bistahieversor is nested within Tyrannosaurinae, [ 25 ] [ 28 ] but it is most often recovered as the sister taxon to Tyrannosauridae instead.
For perspective, that’s one-fourth of the car-crushing bite force of a Tyrannosaurus rex (via Business Insider). Active year-round, saltwater crocodiles are found across Australia, from northern ...
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).
