Chomper, a young Tyrannosaurus rex in The Land Before Time. Dubbed "Jane the Rockford T-Rex," the find was initially considered the first known skeleton of the pygmy tyrannosaurid Nanotyrannus but subsequent research has revealed that it is more likely a juvenile Tyrannosaurus. For example, a 2002 paper in the journal Nature used a mathematical model (validated by applying it to three living animals, [alligators, chickens, and humans; additionally later eight more species including emus and ostriches) to gauge the leg muscle mass needed for fast running (over 40 kilometres per hour (25 mph)). Sharptooth Biographical information Species Tyrannosaurus Gender Male Status Dead Broadcast information Appears in The Land Before Time Tyrannosaurus (pronounced /tɨˌrænəˈsɔːrəs/ or /taɪˌrænoʊˈsɔːrəs/, meaning 'tyrant lizard') is a genus of theropod dinosaur. The feeding habits, physiology and potential speed of T. rex are a few subjects of debate. Erickson, Gregory M., Makovicky, Peter J.; Farlow, James O., Smith MB, & Robinson, JM, 1995. The 'wishbone' is between the forelimbs. Tyrannosauridae Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). If they were smaller, only 18 kilometres per hour (11 mph) walking/jogging might have been possible. Like many bipedal dinosaurs, Tyrannosaurus rex was historically depicted as a 'living tripod', with the body at 45 degrees or less from the vertical and the tail dragging along the ground, similar to a kangaroo. Jane is currently on exhibit at the Burpee Museum of Natural History in Rockford, Illinois. , The largest known T. rex skulls measure up to 5 feet (1.5 m) in length. This discussion is difficult to resolve, as it is unknown how large the leg muscles actually were in Tyrannosaurus.  For the initial mounted skeleton as seen by the public in 1915, Osborn substituted longer, three-fingered forelimbs like those of Allosaurus. Superorder Mowgli - Bart Simpson (The Simpsons) Bagheera - Littlefoot (The Land Before Time) Baloo - Rex the Tyrannosaurus Rex (We're Back! New specimen of. As with many other theropods discovered in the Yixian, the fossil skeleton was preserved with a coat of filamentous structures which are commonly recognized as the precursors of feathers. 2003. invalid names, e.g.  Other tyrannosaurids exhibit extremely similar growth curves, although with lower growth rates corresponding to their lower adult sizes. Fossils of T. rex are found in a variety of rock formations dating to the last three million years of the Cretaceous Period, approximately 68 to 65 million years ago; it was among the last non-avian dinosaurs to exist prior to the Cretaceous–Tertiary extinction event. Vertebral fragments found by E. D. Cope in western South Dakota in 1892 and named as Manospondylus gigas have also been reclassified as T. Tyrannosaurus lived throughout what is now western North America, with a much wider range than other tyrannosaurids. The bigger they come, the harder they fall. , Teeth from what is now documented as a T. rex were found in 1874 by A. It had similar appearances to that of the theropods, excluding the appearances of Spinosaurus and Suchomimus. It’s somehow fitting that those two massive antagonists lived out their co-evolutionary belligerence through the very last days of the very last epoch of the Age of Dinosaurs.". The abundance of fossil material has allowed significant research into many aspects of its biology, including life history and biomechanics. Jaffe, Eric (2006-07-01). Tyrannosauruses with little incorrect designs in The Good Dinosaur. Little of Sharptooth's personality is seen in the movie.  They found that proposed top speeds in excess of 40 kilometres per hour (25 mph) were unfeasible, because they would require very large leg muscles (more than approximately 40–86% of total body mass.) His true name is never revealed; the name given by the characters, 'Sharptooth', refers to the name ofhis species, and in production art, he is simply labelled "Tyrannosaurus Rex". There are two main issues concerning the locomotory abilities of Tyrannosaurus: how well it could turn; and what its maximum straight-line speed was likely to have been.

Size comparison of selected giant theropod dinosaurs, with Tyrannosaurus in purple. Originally thought to belong to a hadrosaurid, examination of the footprint revealed a large 'heel' unknown in ornithopod dinosaur tracks, and traces of what may have been a hallux, the dewclaw-like fourth digit of the tyrannosaur foot. Later Littlefoot's mother appears and saves them fighting the Sharptooth. The biceps brachii muscle of a full-grown Tyrannosaurus rex was capable of lifting 199 kilograms (439 lb) by itself; this number would only increase with other muscles (like the brachialis) acting in concert with the biceps. This is still faster than its most likely prey species, hadrosaurids and ceratopsians. In 1997 this was settled in favor of Maurice Williams, the original land owner, and the fossil collection was sold at auction for USD 7.6 million, making it the most expensive dinosaur skeleton to date. The abundance of fossil material has allowed significant research into many aspects of its biology, including life history and biomechanics. In addition, microstructures resembling blood cells were found inside the matrix and vessels.  Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). It stood in this upright pose for nearly a century, until it was dismantled in 1992. It was discovered in 1983 and identified and documented in 1994..

Chomper is a young purple Tyrannosaurus from The Land Before Time series.  Tyrannosaurids were once commonly thought to be descendants of earlier large theropods such as megalosaurs and carnosaurs, although more recently they were reclassified with the generally smaller coelurosaurs..

"Sue" the Tyrannosaurus, Field Museum of Natural History, Chicago, showing the forelimbs. 1996. Lockley and Hunt suggested that it was very likely the track was made by a Tyrannosaurus rex, which would make it the first known footprint from this species. Brown found another partial skeleton in the Hell Creek Formation in Montana in 1902. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Kenneth Carpenter & Matt Smith.

Characters Osborn used this holotype to describe Tyrannosaurus rex in the same paper in which D. imperiosus was described. Both are relevant to the debate about whether it was a hunter or a scavenger (see below).  By 1970, scientists realized this pose was incorrect and could not have been maintained by a living animal, as it would have resulted in the dislocation or weakening of several joints, including the hips and the articulation between the head and the spinal column.  The skull bones were massive and the nasals and some other bones were fused, preventing movement between them; but many were pneumatized (contained a "honeycomb" of tiny air spaces) which may have made the bones more flexible as well as lighter. D&D Beyond Tyrannosaurus rex is unique among dinosaurs in its place in modern culture; paleontologist Robert Bakker has called it "the most popular dinosaur among people of all ages, all cultures, and all nationalities". family relationships. — The Narrator, descriping Sharptooth's thoughts in The Land Before Time: The Illustrated Story.
