Daspletosaurus has the most unnamed species of any other tyrannosaur yet known?

Daspletosaurus

Daspletosaurus torosus feeds on a ceratopsian.

Daspletosaurus torosus is a medium tyrannosaurine (except maybe for the dubious tyrannosaur Nanotyrannus) and perhaps the smartest one, too. Characteristic to tyrannosaurs it had two fingers on each hand and was probably, at least on some parts of the body, feathered.

The genus Daspletosaurus consists of many unnamed species. One specimen was a stretch-snouted specimen, similar to a juvenile tyannosaur or Alioramus. Another is from the Two Medicine Formation in Montana, United States.

Daspletosaurus torosus grew to 30 feet long and about 12 feet tall. Yet more specific weights are at 3.18 tons

Perhaps the most spectacular thing about this genus is that it coexisted with another tyrannosaur, Gorgosaurus. This tyrannosaur had small differences compared to Daspletosaurus. Yet they were roughly all the same. The coexistence of Gorgosaurus and Daspletosaurus has been explained by scientists through different habits of their predation. Daspletosaurus would eat heavily protected ceratopsians; it's body was very heavy; suitable for big blows that ceratopsids would cause. Gorgosaurus would eat the lighter hadrosaurs (duck-billed-dinosaurs); it's body was very light; so if it got hit by a hadrosaur it wouldn't have got as injured as it would be by a ceratopsian.

Other animals in Daspletosaurus's environment were the sauriscians Troodon, Dromaeosaurus, Elmisaurus, Dromiceiomimus, and Richardoestesia. The ornithiscians in it's environment were Albertaceratops, Centrosaurus, Chasmosaurus, Corythosaurus, Euoplocephalus, Gryposaurus and Lambeosaurus.

TaxonomyEdit

Superorder: Dinosauria

Order: Saurischia

Suborder: Theropoda

Unranked: Coelurosauria/Tyrannoraptora

Superfamily: Tyrannosauroidea

Family: Tyrannosauridae

Subfamily: Tyrannosaurinae

Tribe: Tyrannosaurini

Genus: Daspletosaurus/Tyrannosaurus

Species: Daspletosaurus/Tyrannosaurus torosus


Daspletosaurus torosus fits into the superorder Dinosauria obviously, skipping down, T. rex fits in the unranked suborder Coelurosauria, the superfamily Tyrannosauroidea, the family Tyrannosauridae, the subfamily Tyrannosaurinae, the tribe Tyrannosaurini and the genus Daspletosaurus. Yet controversy remains, some believe it is a member of the genus Tyrannosaurus.
