Introduction to Tyrannosaurus rex, what is Tyrannosaurus rex

Tyrannosaurus rex, or Rex Tyrannosaurus, lived in the Cretaceous period.

The Maastricht period, the last period of the Cretaceous period between about 68.5 million and 65 million years ago, was the extinction of the Cretaceous-Tertiary period.

One of the last non-avian dinosaur species before the affair went unnoticed.

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 weight is about 9 tons, and the head length is about about meters.

The bite force of a Tyrannosaurus rex is generally 90,000 Newtons.

At 120,000 Newtons, with a mouth of up to about 200,000 Newtons, it is also the thickest carnivorous dinosaur.

In terms of physical characteristics, Tyrannosaurus rex has very small forelimbs, only 22% of the length of hind limbs, and the length of the average individual is only about 80 centimeters, compared to the huge size and hind limbs of Tyrannosaurus rex, the forelimbs appear very small, equivalent to an adult's arm.

In terms of length, most carnivorous dinosaurs can surpass Tyrannosaurus rex, including Sharkodontosaurus Sun Hail, Brutesaurus, Quirosaurus, and Sauronsaurus.

But the width of the body of the Tyrannosaurus rex, the width of the cervical vertebrae, the length of the legs, the size of the pelvis, the shoulder blades.

It is much larger than almost all Allosaurus such as Maprosaurus and Quisaurus.

Superfamily dinosaurs, and have carnivorous dragons.

The largest and thickest broad head, cervical vertebrae, trunk and hind limbs.

Carnivorous dragons and theropods of general size and size (e.g., Ceratosaurus, Allosaurus, Spotted Dragon, Yongchuansaurus, etc.) had less than 50% of the body weight of Tyrannosaurus rex, while some stout carnivores (e.g., Tyrannosaurus.

Tyrannosaurus rex) is also only 75%-80% of the body weight of the same Tyrannosaurus rex.

Among the carnivorous dinosaurs, only the brutesaurus and the qui dragon have a body mass index.

Can reach or approach 90% of Tyrannosaurus rex.

In addition, the skeleton of Tyrannosaurus rex is also very thick, the growth cycle of Tyrannosaurus rex ends at the age of 19, and it will not exceed the age of 21 at the latest, when the growth cycle of Tyrannosaurus rex ends, although Tyrannosaurus rex will continue to grow, but it will neither grow nor become taller, its skeleton will become thicker, and the overall look will be stronger.

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 is a carnivorous dinosaur, which feeds on herbivorous dinosaurs and other animals, has sharp and rocky teeth and claws, and is the first 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 more stout, and at the same time very thick and thick fingers.

5. Individual evolutionary characteristics: Scattered 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.

The Tyrannosaurus rex was the strongest and most ferocious king of dinosaurs, with very strong muscles and very strong strength, which could defeat all dinosaurs.

But if you meet a dinosaur born with **, the Tyrannosaurus rex is afraid, like a triceratops with three horns, born to reimburse the strong body of the Tyrannosaurus rex, if you fight with the young and strong triceratops, it is easy to be stabbed in the stomach by the triceratops, even if the Tyrannosaurus rex is strong, it can't survive. Tyrannosaurus rex is also afraid of being hit in the stomach by the tail stick of the ankylosaurus, even if the most muscular Tyrannosaurus rex is hit in the stomach by the tail stick of the ankylosaurus, it is estimated that it will lose strength immediately.
