Description
Reconstruction of Tyrannosaurus with the most minimal amount of feathering plausible by Matthew Martyniuk.
Tyrannosaurus is a monospecific genus of tyrannosaurid coelurosaurs dating from the Maastrichian age of the Upper Cretaceous period (68-66 million years ago). Specimens of T.rex have been found in a vast range, spanning from western Canada (Alberta) all the way to Texas and New Mexico.
Tyrannosaurus was the apex predator of it's habitat, and hunted Triceratops, Edmontosaurus and other such animals. The type specimen of the genus, AMNH 973 (a partial skull and skeleton), was named in 1905 by Henry Fairfield Osborn (though the first known remains, teeth, were discovered in 1874 by Arthur Lakes near Golden, Colorado) and were initially thought to be a species of Ornithomimus (O.grandis), but were later referred to Tyrannosaurus. Another genus, Manospondylus, is technically the correct name for the genus; however it is considered by most scientists to be a senior synonym of T.rex and, by ICZN rule, T.rex supresses all other synonyms; those being Manospondylus, Dinotyrannus, Nanotyrannus, Stygivenator and Dynamosaurus.
Tyrannosaurus was a large animal, measuring 12.4 metres (40 feet) long, 4 metres (13 feet) tall at the hip and weighing between 5.4 and 6.8 metric tonnes (6.0-7.5 short tonnes). The social nature of T.rex is currently debatable, with most scientists opting for a more raptor-like approach, where they were only social when rearing young, and solitary the rest of the year.
Tyrannosaurus' closest relatives were Tarbosaurus and Zheuchengtyrannus.
