1: Tyrannosaurus rex is the largest one in Tyrannosaurus. 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-120,000 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 generic 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, the head of Tyrannosaurus Rex was 1.5m long, with 60 fangs10cm long inside. The head was the most terrible weapon of Tyrannosaurus Rex, but its forelimbs were severely degraded, very short, with two fingers, and it could only lift nearly 60 pounds.
3. Tyrannosaurus Rex was located at the top of the food chain in the late Cretaceous. 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, Pachecatosaurus was not in Tyrannosaurus Rex's diet. Ankylosaurus was rarely hunted by Tyrannosaurus Rex. Other carnivorous dinosaurs distributed in North America at that time, such as Nanotyrannus, might have some competition with Tyrannosaurus Rex, but they were far from being the opponents of Tyrannosaurus Rex.
Extended data:
(1) 1902, Barnum Brown, an American dinosaur fossil collector, found a huge carnivorous animal 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 were quite heavy, he made a special sleigh pulled by horses, which transported the bones 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)20 131February 25th, British and Australian researchers said that a fossil of the pubic bone of Tyrannosaurus rex was found in Australia, which is evidence that Tyrannosaurus rex once lived on the southern hemisphere continent.
The species to which this fossil belongs has been temporarily named NMV P 186069. The researchers speculate that its owner is between 6.5-7.2 meters and weighs about 5.9 tons, while the average Tyrannosaurus Rex can exceed 12 meters in length and weigh over 9 tons. Although the head is very different, both of them have huge heads, degenerated forelimbs and developed hind limbs.
