Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids, and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.[not verified in body] Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus forelimbs were short but unusually powerful for their size and had two clawed digits. The most complete specimen measures up to 12.3 meters (40 feet) in length though T. rex could grow to lengths of over 12.3 m (40 ft), up to 3.96 m (13 ft) tall at the hips, and according to most modern estimates 8.4 metric tons (9.3 short tons) to 14 metric tons (15.4 short tons) in weight. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it is still among the largest known land predators and is estimated to have exerted the strongest bite force among all terrestrial animals. By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. Some experts have suggested the dinosaur was primarily a scavenger. The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology. Most paleontologists today accept that Tyrannosaurus was both an active predator and a scavenger. Specimens of Tyrannosaurus rex include some that are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics. The feeding habits, physiology and potential speed of Tyrannosaurus rex are a few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a second Tyrannosaurus species while others maintain Tarbosaurus is a separate genus. Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus. As the archetypal theropod, Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century, and has been featured in film, advertising, postal stamps, and many other media.

for The Lost Wildlife in Van Helsing : Quest for the Lost World
Suggested by jeanpaulvalley
1907, four years after the events of the last two movies. While Van Helsing and his team have succeeded in arresting the murderers of Rue Morgue, in France, a new threat is coming and this time mankind is directly responsible for it. A peculiar scientist, well-connected to the British government, Doctor Alexander Zorka, discovered proof of the existence of a Lost World, somewhere in South America, deep in the Amazon rainforest. There lies a new metal in the underground mines, which could help Zorka create weapons like no other, which could change the balance of the world in his favor. Our heroes, as they go on a mission to hunt down monsters in the Congo, will be challenged by Koschei, the famous Russian warrior of several centuries who cannot die, and the one he protect, the young Medusa, daughter of the last Gorgon, to warn them of this threat. Unfortunately, they will not be able to prevent the kidnapping of Professor Challenger, who was studing in the country, by Zorka's men to take them to the mysterious South American plateau, but they will be able to count in particular on the expertise of Gill-Man, who heard of this foreign place. To prevent Zorka from causing a world war, our heroes will have to go and explode a world where creatures from another era still exist and where survival can be complicated, even for beings like them !
