	The Tyrannosauridae
		The Tyrannosauridae included such similar animals (in rough order of increasing size) as Albertosaurus, Gorgosaurus, Daspletosaurus, Tarbosaurus, and of course Tyrannosaurus rex.
		A tremendous skeleton of Tyrannosaurus now stands guard in the Valley Life Sciences Building, which houses the UCMP and the Department of Integrative Biology at UC Berkeley.
		A current topic in paleontology that has received much popular press is the question of whether T.rex (or other Tyrannosauridae in general) were predators or scavengers.

	Tyrannosaurus rex, the "Tyrant Lizard King"
		When I talk to children about paleontology, I ask them who their favorite dinosaur is, and with few exceptions, it is Tyrannosaurus rex.
		Tyrannosaurus rex is a member of the Family Tyrannosauridae, which includes other fearsome theropod predators such as Albertosaurus, Daspletosaurus, Gorgosaurus, and Tarbosaurus.
		This group of dinosaurs lived near the very end of the Cretaceous Period (140 to 65 million years ago), and seem to have replaced some of the other large carnivorous dinosaurs as the main predators of the time.

		The latter is regarded a subadult specimen of Tarbosaurus bataar by Carr (1999) and Holtz (in press a, b).
		However, those authors did not include the Asian taxon Tarbosaurus bataar in their (admittedly preliminary) study; Holtz (in press a, b) found that when that Mongolian species is included, the relationship of the unnamed Two Medicine form becomes unresolved with regards to Daspletosaurus and the Tarbosaurus-Tyrannosaurus clade.

		The later and more advanced types had relatively shorter bodies and tails, larger heads, larger hind legs, and (in the case of the giant forms) smaller and smaller forelimbs.
		This evolutionary trend reaches its culmination in the Tyrannosauridae of the the late Cretaceous of the Asiamerican landmass.
		James Madsen tentatively refered this animal to the Tyrannosauridae due to a number of similarities in the ilum, braincase and premaxilla.

		Stokesosaurus clevelandi from the Morrison Formation (Late Jurassic Epoch, Kimmeridgian Age) of Utah, USA, is known from the type ilium, a premaxilla (Madsen 1974), and a partial braincase (Chure and Madsen 1998).
		Madsen (1974) provisionally refered this 2-3 m long dinosaur to Tyrannosauridae because of the presence of a single midline iliac crest dorsal to the supracetabular crest, and because of incipient development of a ventral hooklike projection amd medial support on the preacetabular blade.

	In Hand Museum - Tyrannosaurus rex
		Most theropod dinosaurs fall into three subgroups: the more primitive ceratosaurs; the large carnosaurs; and the smaller, bird like coelurosaurs.
		To go one more step, we group carnosaurs into two families: Allosauridae and Tyrannosauridae.
		While it was larger than a human brain, it was small for such a large animal and was mostly dedicated to sight and smell rather than thinking.

	PALEONTOLOGY: ON THE ANCESTOR OF TYRANNOSAURUS REX
		Details of the anatomy of this relatively small species indicate that it is the most ancient known member of the line that led to Tyrannosaurus rex and its giant kin, the Tyrannosauridae or "tyrant dinosaurs".
		This distinctiveness, as well as their relatively rich fossil record, both in completeness of skeletons and numbers of individuals, has made the tyrannosaurids the subject of numerous palaeobiological studies[4,5].
		The evolution of the distinctive adaptations present in the better-preserved Late Cretaceous forms such as Tyrannosaurus, Gorgosaurus, and Tarbosaurus has transformed their skulls, limbs, and vertebrae, thereby "overwriting" much of the anatomical traces of their ancestry.

	What's the difference between Tyrannosauridae, Tyrannosaurinae, etc.?
		For example, the family containing Tyrannosaurus, together with similar genera such as Alectrosaurus, Gorgosaurus and Daspletosaurus, is called the ``Tyrannosauridae''.
		Such a grouping is called a superfamily, and its name is made by replacing the ending of the type genus name by the suffix ``oidea'' (which, yes, is also painfully easy to misread as a family name.)
		Unfortunately, the superfamily Tyrannosauroidea is not a very interesting example, since no genus outside of the Tyrannosauridae is known to be inside it - although several, such as Stokesosaurus and Siamotyrannus are candidates for this classification.

		Carr (2005) found it to be the sister taxon of NMMNH P-27469, both being sister to Tyrannosauridae, based on cranial characters.

		Tyrannosauroidea contem portanto Tyrannosauridae e vários outros taxa, infelizmente mal conhecidos, quase sempre devido à natureza muito fragmentada e incompleta do material osteológico preservado.
		Antes, Zinke (1998), tinha referido a Tyrannosauridae 3 dentes pré-maxilares (com a característica morfologia em D) e 13 dentes maxilares e dentários, material também encontrado na mina da Guimarota.
		Assim, estes investigadores sugeriram que o teropode pode constituir o grupo irmão para Tyrannosauridae, inferência suportada pelo carácter intermédio de várias características, entre os coelurossaurios não tyrannossaurídeos e os tyrannossaurídeos (por exemplo, a arcada dos dentes pré-maxilares está orientada mais medio lateralmente do que nos não tyrannossaurídeos, mas não tanto como nos tyrannossaurídeos).

		The Sino-Swedish Paleontological Expeditions of 1927-31 to the Gobi in China turned up some nondescript tyrannosaurid material, some of which was described by Anders Birger Bohlin in 1953 and referred to Prodeinodon (under the misspelled name Deinodon mongoliensis).

		Recent research by The Royal Tyrrell Museum shows that Albertosaurus and Gorgosaurus really do represent different genera.

		The tyrannosaurids represent the most famous of all theropods, and include the legendary Tyrannosaurus rex--the "tyrant king lizard." Tyrannosaurids represent a major radiation of theropods in the Cretaceous, and their taxonomy and phylogeny has recently been reviewed by Holtz (in Tanke and Carpenter 2001).
		Holophyly of Tyrannosauridae is robustly supported, with Holtz's most recent analysis isolating 39 synapomorphies of the tyrannosaurid lineage.
