Tyrannosauridae (or tyrannosaurids, meaning " tyrant lizards") is a family of coelurosaurian theropod dinosaurs that comprises two subfamilies containing up to fifteen genera, including the eponymous Tyrannosaurus. The exact number of genera is controversial, with some experts recognizing as few as three.
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives. Tyrannosauroids lived on the Laurasian supercontinent beginning in the Jurassic Period.
Tyrannosaurus (/ tɪˌrænəˈsɔːrəs, taɪ -/) [ a ] is a genus of large theropod dinosaur. The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
Classification of dinosaurs. Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia ...
Yutyrannus was a large bipedal predator. The holotype and oldest-known specimen has an estimated length of 9 metres (29.5 ft) and an estimated weight of about 1,414 kilograms (3,117 lb). [1] In 2016, Gregory S. Paul gave lower estimations of 7.5 metres (24.6 ft) and 1.1 tonnes (1.2 short tons). [4] Its skull has an estimated length of 905 ...
T. rex was fully grown at around 18-21 years. Perhaps the largest-known Tyrannosaurus, a specimen named Sue at the Field Museum in Chicago, is 40-1/2 feet (12.3 meters) long.
Trix (dinosaur) Trix is a Tyrannosaurus rex specimen excavated in 2013 in Montana, United States by a team of paleontologists from the Naturalis Biodiversity Center in Leiden, the Netherlands and Black Hills institute of Geological Research in South Dakota. This Tyrannosaurus, over thirty years old – the oldest known Tyrannosaurus specimen ...
This multispecies Tyrannosaurus classification is, however, not widely accepted by most paleontologists. [36] In some phylogenetic studies Bistahieversor is nested within Tyrannosaurinae, [ 25 ] [ 28 ] but it is most often recovered as the sister taxon to Tyrannosauridae instead.
