The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics. Soft tissue and proteins have been reported in at least one of these specimens. Specimens of Tyrannosaurus rex include some that are nearly complete skeletons. Most paleontologists today accept that Tyrannosaurus was both an active predator and a scavenger. The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology. Some experts have suggested the dinosaur was primarily a scavenger. By far the largest carnivore in its environment and the infamous ' king of the dinosaurs', Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, juvenile armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. 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. rex could grow to lengths of around 13.4 meters (44.0 feet), up to 4.36 meters (14 feet) tall at the hips, and 8.4 metric tons (9.3 short tons) to 14 metric tons (15.4 short tons) in weight. The most complete specimen measures up to 12.3-13.2 meters (40.4-43.30 feet) in length and stands 3.66-3.99 meters (12-13 feet) tall, though according to most modern estimates, T. Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had 2 clawed digits. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. It was the largest and the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 68-66 million years ago. Tyrannosaurus had a much wider range than other tyrannosaurids. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. rex or colloquially T-Rex, is one of the best represented members of the genus as well as all theropods. The species Tyrannosaurus rex ( rex meaning 'king' in Latin), often called T. And honestly, this is one creature we're glad remains in the past.Tyrannosaurus (meaning 'tyrant lizard') is an extinct genus of large theropod dinosaur. The fossils are about “79.5 million years old,” says Voris. He adds that this is the oldest tyrannosaurus species from Canada-and the first new Tyrannosaurus species found in the country within the last 50 years. Voris says that he knew Thanatos was a new kind of tyrannosaur because of distinct characteristics on the creature's skull, the most prominent of which are ridges along the entirety of the upper jaw.

It wasn't until nine years later that Ph.D student, Jared Voris, recognized the specimens as “a new species of tyrannosaur,” Zelenitsky adds. The remains were originally found in 2010 near Canada's Bow River by John and Sandra De Groot (hence the degrootorum part of Thanatos' scientific name). The fossilized bones used to identify this new species “had been in a museum drawer” for nearly a decade before being studied, Zelenitsky says. 10 Dinosaur Toys for Prehistoric Playtime.Opal Miner Unearths New Species of Dinosaur.Allosaurus Jimmadseni Was a Meat-Eating Badass.
