Origin and characteristics of Tyrannosaurus rex, characteristics of Tyrannosaurus rex

The Tyrannosaurus rex was 15 meters long, and the largest individual was 17 meters and about 10 tons.

Tyrannosaurus rex has unique characteristics in terms of bones, body size, carnivorous, growth cycle, and individual evolution, which are described as follows:

1. Skeletal characteristics: the posterior frontal bone is missing, the humerus has a low triangular crest, attached to the sternoclavicular deltoid muscle, and the length is about 1 3 to 1 2 of the humerus. There is a protruding mass in the posterior part of the intestinal bone, and the acetabulum is perforated.

The tibia has a broad terminal margin with a posterior flange. The talus has a distinct superior process that fits the tibia.

2. Body type characteristics: Huge body size, it is the largest species in the tyrannosaur family, with an average hip height of about 4 meters. The highest hip height can reach about meters, and the highest head height is nearly 6 meters. The average weight is about 9 tons, (the ecological average is about a ton), the heaviest tonnage, and the head length is about a meter.

3. Carnivorous characteristics: Tyrannosaurus rex belongs to carnivorous dinosaurs, feeding on herbivorous dinosaurs and other animals, with sharp teeth and claws, and is the leader of Tyrannosaurus rex to hunt other herbivorous dinosaurs.

4. Characteristics of the growth cycle: Tyrannosaurus rex does not grow all the time, its growth cycle generally ends at the age of 19, at the latest not more than 21 years old, after the end of the growth cycle, although it does not grow tall or long, but its skeleton will grow, become thicker, and at the same time very thick.

5. Individual evolutionary characteristics: It can be divided into two modes or forms, similar to some other theropod dinosaurs. One of them is thicker, while the other is more slender. Tyrannosaurus rex possessed hermaphroditic forms, while the stout form was generally considered female.

A ferocious carnivorous dinosaur. Survived in the Late Cretaceous. It is the largest known terrestrial meat, with a body length of 15 meters, a length of meters on the head alone, and a height of 6 meters on the body.

The skull is bulky, high and flattened, with two large eyeholes and oval orbits. The teeth are extremely well developed. There are traces of coarse movable ligament fixation between the tooth bones, the hip bones, and the anterior articular bones.

The cervical bone is short, with 9 10 cervical vertebrae, and its structure is characterized by a short and wide type. The shoulder girdle is degenerate, the shoulder blade is elongated, and the humerus is short, only half as long as the shoulder blade. The forefoot is degenerate and weak, with only two fingers and may have a third finger remaining.

The Tyrannosaurus rex girdle is very well developed and extremely compact, not only the intestinal bone and the vertebrae are tightly healed, but the distal ends of the ischial bone and pubic bone are also attached to each other; The distal pubic bone is enlarged and has a pedidal-like process, while the distal ischial bone is club-shaped. Such a thick belt structure indicates that its hind limbs are highly mobile. Tyrannosaurus rex lived mainly in hilly areas and preyed on herbivorous reptiles.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately

Hello, it's a pleasure to answer for you that the Tyrannosaurus rex has a big head. Tyrannosaurus rex had short forelimbs and two fingers on each hand; The hind legs are large and powerful, with three toes on each foot. Each finger and each toe is accompanied by a claw.

Tyrannosaurus rex had a thin, stiff strip with a pointed tail. It has a total of 60 teeth, each of which is 9 inches long and all of them are sharp. When a tooth is lost, a new tooth erupts.

The Tyrannosaurus rex walked on two legs and was able to run very fast, reaching speeds of up to 30 miles per hour. It has a good sense of sight and smell. The Tyrannosaurus rex had a big head, and it was a smart dinosaur.

Tyrannosaurus rex [1] was one of the last non-avian dinosaur species to survive in the Maastricht period (MAA) at the end of the Cretaceous period, about 68.5 million to 65 million years ago, and was one of the last non-avian dinosaur species before the Cretaceous-Tertiary extinction event. Fossils are found in the United States and Canada in North America, and were among the last dinosaurs to become extinct. Tyrannosaurus rex is the largest of the Tyrannosauridae family.

The body length is about meters. The average hip height is about 4 meters. The highest hip height can reach about meters, and the highest head height is nearly 6 meters.

The average spine weight is about 9 tons, the heaviest ton, and the head length is about 1 meter. The bite force is generally 90,000 Newtons to 120,000 Newtons, and the maximum end of the mouth can reach about 200,000 Newtons, and it is also the thickest carnivorous dinosaur. The genus name of Tyrannosaurus rex means the brutal lizard king in ancient Greek, and the species name means king in Latin.

Some scientists believe that the Asian Tyrannosaurus bataar was the first effective species of the Tyrannosaurus superfamily, while others believe that Tyrannosaurus was a separate genus. In addition to this, many species of the Tyrannosauridae family have been proposed, but most of them are considered synonyms of Tyrannosaurus rex, or are classified in other genera. [2] A team of paleontologists confirmed that the Tyrannosaurus fossil, discovered in Western Canada in 1991, was the largest Tyrannosaurus ever found in the world.

The Tyrannosaurus rex, named "Scotty," was 13 meters long and probably weighed more than 8,800 kilograms, surpassing all carnivorous dinosaurs found in the past, according to the University of Alberta team in Canada. On May 18, 2019, the skeleton of the world's largest Tyrannosaurus rex, Scotty, was exhibited in Suskhotchewan, Canada, with a length of 13 meters and a weight of more than one ton before its death, which was 5% heavier than the previously considered largest Tyrannosaurus rex.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

1. Habits.

The Tyrannosaurus rex was at the top of the food chain in the late Cretaceous period, when a variety of dinosaurs in North America were basically its prey, and sometimes they also attacked long-necked herbivorous dinosaurs like Alamosaurus.

2. Living environment.

Tyrannosaurus rex was a two-legged walker that lived mainly over a wide area of western North America at the end of the Cretaceous period 100 million years ago. Near the site where the Tyrannosaurus rex was found, there are still conifers from the Tyrannosaurus rex era and its relatives. The scene was similar to that of Florida or southern Georgia, with small trees about 15-25 meters tall and trunks less than meters in diameter.

In its lifetime, all modern plants appeared. There are fewer species of dinosaurs than Jurassic, so the environment in which Tyrannosaurus rex lived is unimaginable. Flowering plants that appeared in the early Cretaceous period, the period when Tyrannosaurus rex lived dominated the world's ecosystem, 90% of the leaf fossils were found in North Dakota, and 90% of the more than 30,000 leaf fossils collected belonged to broad-leaved plants.

Answer: The forelimbs of the Tyrannosaurus rex can play a role in balancing the large head, and it can also play a role in hunting and grabbing. Tyrannosaurus rex is the largest of the Tyrannosauridae family, with a body length of about one meter. The average hip height is about 4 meters.

The highest hip height can reach about meters, and the highest head height is nearly 6 meters. The Tyrannosaurus rex has a bite force of 90,000 Newtons to 120,000 Newtons, and the end of the mouth can reach up to 200,000 Newtons.

1. The forelimbs of Tyrannosaurus rex can play a role in balancing the huge head, and can also play a certain role in hunting and grabbing.

2. Tyrannosaurus rex is the largest of the Tyrannosauridae family, with a body length of about one meter. The average hip height is about 4 meters. The highest hip height can reach about meters, and the highest head height is nearly 6 meters.

3. The Tyrannosaurus rex has a bite force of 90,000 Newtons to 120,000 Newtons, and the end of the mouth can reach a maximum of 200,000 Newtons.

4. Judging from the shape of the skull of Tyrannosaurus rex, its upper jaw is wide and the lower jaw is narrow, and the force exerted by the upper and lower jaws is not completely opposite when biting, which is conducive to biting off the bones. Tyrannosaurus rex's teeth were cone-shaped like bananas, which were suitable for crushing bones, while most carnivorous dinosaurs' teeth were mostly used for piercing and cutting. The structure of its skull suggests that the predatory behavior of Tyrannosaurus rex may have been different from that of most theropod dinosaurs.

The head is large, with a triangular sharp teeth, short forelimbs with two fingers, and the hindlimbs are thick and powerful, and the body is large, up to 6 meters tall.

Tyrannosaurus rex lived 65 million to 68 million years ago, lived in North America, only 3 claws on each foot, walked very fast, about 30 kilometers per hour, full of 50 sawtooth teeth, each tooth is more than 6 inches long, they use this giant tooth to prey on animals, Tyrannosaurus rex likes to eat animals such as duck-billed dinosaurs, triceratops dinosaurs and other herbivores. The Natural History Museum in London, England, recently exhibited a new model of a Tyrannosaurus rex, which was made by a Japanese company, 23 feet long and nearly 14 feet high, and cost $330,000. This model is not your average model, it is different, not only can it move, but it can also make a terrible roar, which is nothing, and what is even more strange is that it also emits smells.

Tyrannosaurus rex is a ferocious large carnivore, so the smell on its body should be very complex, and it is really not easy to "copy" its original smell. The smell of Tyrannosaurus rex is a mixture of the fishy, sour and spicy smell of the swamp, and the smell of the earth.

Tyrannosaurus rex is 12 meters long. It weighs 5-6t and is about five meters tall. Strong physique. The hind limbs are thick and powerful. It is also the dinosaur with the strongest bite force.

The body is 6 meters long, and it will declare its territory and not let others in.

Tyrannosaurus rex is the largest of the Tyrannosauridae family.
