	tyrannosaurus rex - Article and Reference from OnPedia.com
		Tyrannosaurus rex ("tyrant lizard king") was a giant carnivorous theropod dinosaur from the Upper Maastrichtian, the last stage of the Cretaceous period, 66-65 million years ago.
		It was assigned to Tyrannosaurus rex in 1912 by Henry Osborn.
		Relative to other carnivorous dinosaurs such as Allosaurus, Tyrannosaurus appears to have had a sizeable brain, but it was probably not particularly intelligent by mammalian standards.

	PALEAUTONOMY.COM: Dinosaurs - Tyrannosaurus
		For many years, Tyrannosaurus was the largest known terrestrial carnivore of all time, and this has led the T-Rex to be the star and subject of many fictional accounts of dinosaurs.
		Tyrannosaurus' brain was long and close to cylindrical, and it was probably among the most intelligent theropods, as measured by EQ.
		Tyrannosaurus are believed to have required extensive geographic feeding ranges, nearly as large as a U.S. state.

	Tyrannosaurus (Site not responding. Last check: 2007-10-25)
		Tyrannosaurus ([taɪ'ræn.əʊ.sɔːr.ʌs]) meaning "tyrant lizard" because of its size and large teeth and claws (Greek tyrannos meaning 'tyrant' and sauros meaning 'lizard' and Latin rex meaning 'king'), also known colloquially as "T.
		Tyrannosaurus is now a prime subject of ongoing scientific research and popular culture, although there have been published reports of larger predatory dinosaurs (such as Giganotosaurus and Spinosaurus).
		For over 50 years, Tyrannosaurus had been depicted as a 'living tripod', with the body at 45 degrees or less from vertical and the tail dragging along the ground and acting as a balance for the legs.

		Relative toother carnivorous dinosaurs such as Allosaurus, Tyrannosaurus appears to have had a sizeable brain, but it wasprobably not particularly intelligent by mammalian standards.
		J. von Arrensdorff speculatesthat Tyrannosaurus may have used a similar strategy to that of the KomodoDragon relying on one bite followed by steady pursuit of its stricken prey.
		The gigantic theropods are believed to have required extensive geographic feeding ranges - as large as acontinent, and that theropods the size of T. Rex arose in response to the retreat of the Western Interior Seaway of NorthAmerica, 69 million years ago, which would have increased the size of the feeding range.

	Discover the Amazing Story of Daspletosaurus torosus.
		The Canadian Museum of Nature brings Daspletosaurus torosus to life in the amazing story of this dinosaur, whose skeleton is on display in our Dinosaur Gallery, and which is soon to be complemented by a fleshed-out, full-sized model.
		For some unknown reason, Daspletosaurus torosus came to an end about three million years before the great dinosaur extinction.
		Daspletosaurus torosus was an enormous animal, almost nine metres in length and weighing 3 tonnes.

		It has been suggested that Daspletosaurus is a direct ancestor to Tyrannosaurus.
		The massive, stocky construct of the two tyrannosaurus and certain similarities in skull structures seem to be indicators of a close phylogenetic relationship between the two genera.
		Some have even gone further to suggest that Daspletosaurus is in fact a species of Tyrannosaurus (Daspletosaurus torosus = Tyrannosaurus torosus), but this has not been universally acknowledged.

		Tyrannosaurus rex: because this injury shows subsequent regrowth of bone, this wound was inflicted on a living animal rather than a carcass.
		Tyrannosaurid dentition is markedly heterodont, perhaps indicating a partition of different sectors of the jaw for different function: scraping for the incisiform premaxillary teeth versus tearing and crushing for the lateral teeth, for example.
		Tyrannosaurus rex would be subjected to fatal damage if it fell, suggesting that very large individual tyrannosaurids may not have been as cursorial as younger or smaller specimens.

		Actually this is not surprising as Tyrannosaurus after all, was decended from the Coelurosaurs (and is a coelurosaur by the way), the smartest dinosaur group and inherted their complex brains too.
		Tyrannosaurus was an advanced carnivorous dinosaur, and it's hardly surprising that he was extremly smart.
		But it merits attention in Tyrannosaurus' case after the discovery of micro-abrasive cubular serrations on the teeth, a sure sign for adapations to harbour an extremely septic bite.(carnviores not using septic biteshave normal delta-serrations, which Giganotosaurus had) A Tyrannosaurus is going to be much much more septic than your average carnviore bite.

	Tyrannosauridae
		Although old drawings of Tyrannosaurus rex give the beast an almost erect stance and a long reptilian tail, this is now known to be incorrect.
		The famous Tyrannosaurus rex, the last and most advanced of the tyrannosaurs, had the smallest forelimbs (proportionally speaking) of any dinosaur, and it is likely that if their evolution had not been cut short by the terminal Mesozoic catastrophe they would have lost their arms altogether.
		This animal clearly belongs under the genus Tyrannosaurus, and it is only the annoying tendency of vertebrate paleontolgists to give every new discovery a new generic name that results in them being considered distinct.

	Nanotyrannus; Gigadispute
		In the BCF scenario, tyrannosaurids were the cursorial descendants of volant dino-birds in which the number of wing digits was reduced to two--a continuation of the progressive loss of the wing digits that began with the origin of Aves in the Triassic.
		If Nanotyrannus had a bimodal growth pattern, say rapid growth from hatchling to subadult, then slower indeterminate growth from subadult to large adult, it could well have had skull-bone fusion already at the subadult stage.
		Although the teeth are plastered in, it still seems to have the wrong tooth count to be a T.

		Having examined the skull of Tyrannosaurus bataar, there is nothing preserved in this specimen which forbids it from being EITHER a specimen of Tyrannosaurus rex OR a specimen of "Tarbosaurus" efremovi.
		In any case, there really isn't any good support for separating Tyrannosaurus and Tarbosaurus at a generic level: I'd almost feel confident enough to follow Jim Farlow's suggestion (in the 1993 paper on theropod energetics) and just call them all T.
