It was extremely wide at the rear but had a narrow snout, allowing unusually good binocular vision.The skull bones were massive and the nasals and some other bones were fused, preventing movement between them; but many were pneumatized (contained a "honeycomb" of tiny air spaces) which may have made the bones more flexible as well as lighter.Growth curves can be developed when the ages of different specimens are plotted on a graph along with their mass. rex growth curve is S-shaped, with juveniles remaining under 1800 kg (2 short tons) until approximately 14 years of age, when body size began to increase dramatically. rex would gain an average of 600 kg (1,300 lb) a year for the next four years.
Large fenestrae (openings) in the skull reduced weight and provided areas for muscle attachment, as in all carnivorous theropods.
But in other respects Tyrannosaurus’ skull was significantly different from those of large non-tyrannosauroid theropods.
The largest found so far is estimated to have been 30 centimetres (12 in) long including the root when the animal was alive, making it the largest tooth of any carnivorous dinosaur.
The identification of several specimens as juvenile Tyrannosaurus rex has allowed scientists to document ontogenetic changes in the species, estimate the lifespan, and determine how quickly the animals would have grown.
Tyrannosaurus (pronounced /tɨˌrænəˈsɔːrəs/ or /taɪˌrænoʊˈsɔːrəs/, meaning 'tyrant lizard') is a genus of theropod dinosaur.
The famous species Tyrannosaurus rex ('rex' meaning 'king' in Latin), commonly abbreviated to T.
The abundance of fossil material has allowed significant research into many aspects of its biology, including life history and biomechanics.
The feeding habits, physiology and potential speed of T. Its taxonomy is also controversial, with some scientists considering Tarbosaurus bataar from Asia to represent a second species of Tyrannosaurus and others maintaining Tarbosaurus as a separate genus.
Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail.
Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two primary digits, along with a possible third vestigial digit. rex in size, it was the largest known tyrannosaurid and one of the largest known land predators, measuring up to 13 metres (43 ft.) in length, By far the largest carnivore in its environment, T.
rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. rex have been identified, some of which are nearly complete skeletons.Tags: Adult Dating, affair dating, sex dating
