1: Tyrannosaurus Rex is the largest one among Tyrannosaurus Rex. The body length is about 1 1.5- 14.7 meters. The average hip height is about 4 meters. The highest hip height can reach about 5.2 meters, and the highest head height is nearly 6 meters. The average weight is about 9 tons (the ecological average is about 7.6 tons), the heaviest weight is 14.85 tons, and the head length is about 1.55 meters. The bite force is generally 90,000 Newton-1.20,000 Newton, and the maximum at the end of the mouth can reach about 200,000 Newton. It is also the strongest carnivorous dinosaur.
2. The common name of Tyrannosaurus Rex means "cruel lizard king" in ancient Greek, and its name means king in Latin. Once known as the largest carnivorous dinosaur, Tyrannosaurus Rex had a head length of 1.5m and 60 fangs with a length of 10cm inside. The head was once the most terrible weapon of Tyrannosaurus Rex, but its forelimbs were severely degraded, with only two fingers, and it could only lift nearly 60 kilograms.
3. In the late Cretaceous, Tyrannosaurus rex was at the top of the food chain. At that time, all kinds of dinosaurs in North America could basically be its prey, and sometimes they attacked long-necked herbivorous dinosaurs like Alamolon. Because of its small size, Pacicantosaurus was not in Tyrannosaurus Rex's diet. Ankylosaurus is rarely hunted by Tyrannosaurus Rex. Other carnivorous dinosaurs distributed in North America at that time, such as Nanotyrannus, may have some competition with Tyrannosaurus Rex, but they are far from being the opponents of Tyrannosaurus Rex.
Extended data:
(1) 1902 Barnum Brown, an American dinosaur fossil collector, found a huge carnivore skeleton in Hale Creek, Montana, USA, when he was a staff member of the National Museum of History. In the following two summers, he successively excavated the skeleton from the hard sandstone. Because the bones are quite heavy, he made a special sleigh drawn by horses and transported them to the nearby highway. What he found was the skeleton of the first Tyrannosaurus Rex.
(2) 19 10, the expedition led by Barnum Brown began a large-scale collection in the Red Deer River Canyon in Alberta, Canada. Brown found extremely well-preserved skeleton fossils such as dragon, helmet dragon and sharp-horned dragon and some dinosaur skin fossils there.
(3)2065 438+03, 13 On February 25th, British and Australian researchers said that the fossil of the pubic bone of Tyrannosaurus rex was found in Australia, which is evidence that Tyrannosaurus rex once lived in the southern hemisphere continent.
The species to which this fossil belongs is temporarily named NMV P 186069. The researchers speculate that its owner is 6.5-7.2 meters tall and weighs about 5.9 tons, while the average Tyrannosaurus Rex can exceed 12 meters in length and weigh more than 9 tons. Although the head is very different, both of them have huge heads, forelimbs are degenerated and hind limbs are developed.
