Why did some giant dinosaurs eat meat smaller?

Dozens of times more flexible because they really can't beat large carnivorous dinosaurs that are several times larger than them, and some of them are inflexible, so they will become smaller, just to protect themselves.

Because they can't fight big dinosaurs, they have to be smaller to protect themselves.

Hello, dear, very good to guess the bad answer for you. That kind of dinosaur needs to hunt, and many of them need to rely on flexible hands to hunt, and the large ones have poor dexterity. Moreover, the living conditions of predatory dinosaurs were relatively poor, and they had to go hungry if they didn't catch food.

Unlike herbivorous ones, they don't have to worry about food, so they can't be too big, otherwise they will eat a lot and starve to death if they don't have enough to eat! The vast majority of predators in the animal kingdom are for survival, and there are very few situations like "I'll be happy if I kill you" and "I don't kill you for food, just kill for fun"! If the vegan dinosaur is too small to eat, it may be killed and eaten up quickly!

So they have to be big enough.

When the dinosaurs first evolved, they were all carnivorous animals, and they lived by eating foreign reptiles. At first, they were a "minority", but later they became the dominant animals on land.

Due to the extinction of a large number of foreign reptiles that ate plants before, there is a large surplus of plant food on the earth, so that some of the dinosaurs that eat meat have changed from eating meat to vegetarian. As a result, dinosaurs have a distinction between meat and plant food.

Meat-eating dinosaurs mainly lived on plant-eating dinosaurs, the former being a minority and the latter being the vast majority.

Because their forelimbs are small and their hindlimbs are well developed. At the same time, when the two hind legs are running, the presence of the forelimbs has a balancing effect on the movements of the carnivorous dinosaurs such as turning, and can also reduce resistance.

Dinosaurs are a type of reptile from the Mesozoic Era, with vigorous limbs, long tails and huge bodies that portray most dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).

Carnivorous dinosaurs mostly belong to the theropod order, and they are often referred to as carnivorous dinosaurs or theropod carnivorous dinosaurs. The top 10 largest carnivorous dinosaurs are: Spinosaurus, Tyrannosaurus rex, Brutesaurus, Maprosaurus, Sharkodontosaurus, Osalasaurus, Australopithecus, Zhucheng Tyrannosaurus, Quirosaurus, and Syatzsaurus, (according to body size), and Spinosaurus is currently the largest of all carnivorous dinosaurs.

In addition, the Fear of the Band, the Gilan Silly Dust Thunderbolt, and the Tallspinosaurus Sauronsaurus are also extremely large carnivorous dinosaurs.

Summary. Hello, this is determined by body type and character. Its best character is to adapt to the environment, which is a manifestation of natural selection and survival of the fittest.

For example, Tyrannosaurus rex: also known as Tyrannosaurus rex, is a large theropod dinosaur. Born in the late Cretaceous period, with a length of up to 13 meters, a hip height of about 4 meters, and a weight of about 8 to tons, the bite force of the Tyrannosaurus rex is the largest among carnivorous dinosaurs, and its average bite force is about 10 tons or more.

The head, cervical vertebrae, hind limbs, and trunk of Tyrannosaurus rex are all thick and broad, with particularly small forelimbs, probably used to maintain a huge head balance. Tyrannosaurus rex's teeth were capable of snapping bones and crushing bones. The Tyrannosaurus rex was very combative, in a top killer position, and sometimes attacked Alamosaurus as close to 60 tons.

Hello, I have seen your question and am sorting out the answer, please wait a while for you.

Hello, Nianzi your problem I have seen Ha Now I am hand-hungry for you to return to the limb content, but it takes a little time, please wait patiently, thank you

Hello, this is determined by body type and character. Its best character is to adapt to the environment, which is a manifestation of natural selection and survival of the fittest. Like Tyrannosaurus rex:

Also known as Tyrannosaurus, it is a large theropod dinosaur. Born in the late Cretaceous period, with a body length of up to 13 meters, a hip height of about 4 meters, and a weight of about 8 to tons, the bite force of the Tyrannosaurus rex is the largest among carnivorous dinosaurs, and its average bite force is about 10 tons or more. The head, cervical vertebrae, hind limbs, and trunk of the Tyrannosaurus rex were thick and broad, and the forelimbs were particularly small, probably used to keep the huge head flat and balanced.

Tyrannosaurus rex's teeth were capable of snapping bones and crushing bones. The Tyrannosaurus rex is very strong in combat and is in the position of a top killer, and when it has a pin, it will also attack the Alamosaurus which is close to 60 tons.

Do you think there's anything else you can help with?

Some predatory dinosaurs will gradually become smaller in order to survive.

The vast majority of predators in the animal kingdom are for survival, and predatory dinosaurs need to hunt, many of which need to rely on flexible dexterity to hunt, and the large body has poor flexibility. Moreover, the living conditions of predatory dinosaurs were relatively poor, and they would go hungry if they didn't catch food. Unlike herbivorous dinosaurs, reeds don't have to worry about food, so predatory dinosaurs also look more and more like birds:

The bones are hollow, the body is light, the brain is swollen, and the movement is agile; The forelimbs are getting longer and longer, and they can flapp like bird wings.

Causes of the extinction of the dinosaurs:

1. According to the most mainstream theory at present, the extinction of the dinosaurs was caused by the impact of a huge asteroid on the earth in 65 million years.

2. At that time, the asteroid that hit the earth was about 10 kilometers in diameter, and the impact point was located near Chicxulub in today's Yucatan Peninsula in Mexico.

3. However, it is incomplete to consider the consequences of this asteroid simply from the perspective of hydrogen bombs, because the mass and size of the earth are far above this asteroid, which means that the damage caused by the asteroid impact itself is limited, and it will only cause the rapid death of organisms in the area near the impact site, but will not lead to the death of species distributed around the world. <>
