Tyrannosaurus - Tyrannosaurus Rex
Tyrannosaurus[nb 1] is a genus of tyrannosaurid theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the best represented of these 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. 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, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they 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 6 metric tons (6.6 short tons) to 8 metric tons (8.8 short tons) in weight.
Shantungosaurus - Shantungosaurus Giganteus
Shantungosaurus giganteus is one of the largest known ornithischians. The type skull is 1.63 metres (5.3 ft) long,[1] and the composite skeleton mounted at the Geological Institute of China in Beijing measures 14.7 metres (48 ft) in length. Another mounted skeleton, originally referred to as Zhuchengosaurus maximus, measures 16.6 metres (54 ft) in length. The largest individuals may have weighed as much as 16 tonnes (18 short tons). Like all hadrosaurs its beak was toothless, but its jaws were packed with around 1,500 tiny chewing teeth. A large hole near its nostrils may have been covered by a loose flap of skin, which could be inflated to make sounds.
