Why are dinosaurs extinct? Why did dinosaurs go extinct?

Lizards refer to the phylum Vertebrates reptilia with the order Squamata Lacertilia

Crocodiles refer to the phylum Vertebrates Repitilia, Archosaurus, Alligators, and crocodylia

Dinosaurs refer to the phylum Vertebrates of the class Repitilia bipore. Biology is classified as an umbrella heading. The biggest difference between dinosaurs and other reptiles is the way they stand and the way they walk, dinosaurs have a completely upright posture and their limbs are built directly below their bodies.

This structure is more advantageous for walking and running than other types of reptiles, such as crocodiles, whose limbs are stretched outward.

Lizards belong to the reptile family Dinosaurs are reptilian ancestors and dinosaurs are of the same era But the two are not to be confused crocodiles are also crocodiles Crocodiles are just similar to dinosaurs Belong to dinosaurs But they are not equal to dinosaurs The descendants of real dinosaurs are birds.

Crocodile lizards.

Dinosaurs, lizards, and crocodiles all belong to reptiles, but they are three different species, and it cannot be said that dinosaurs are extinct, and lizards and crocodiles are also extinct.

For example: both monkeys and humans belong to mammals and both belong to primates, but is playing monkey the same as playing man?

Maybe it's true that as you said, the dinosaurs were only partially extinct, but at that time, meteorites crashed into the earth, leading to the eruption of ** mountains, and the problem of meteorite fragments spreading everywhere, most dinosaurs have become extinct, and crocodiles are only a species that evolved later, and cannot be compared with dinosaurs.

The claim of dinosaur extinction refers to the fact that there are no creatures similar to the unearthed dinosaur fossils in modern times, and the ones you are talking about may have evolved from dinosaurs, and they are definitely not dinosaurs. From appearance to food to habits, it is not.

In fact, dinosaurs are all around us, and the birds in the sky are ornithistosaurus and Chinese ornithosaurus evolution, Komodo dragons, also known as Komodo dragons, are carnivorous dinosaurs evolution.

Because lizards, crocodiles are just the evolution of dinosaurs, not dinosaurs.

Reasons for the extinction of dinosaurs: 1. Meteorite collision theory: 65 million years ago, a huge meteorite hit the earth, making the dinosaurs that reigned on the earth for 100 million years extinct, causing the earth to last for several months in a dark state.

During this period, many creatures, including dinosaurs, became extinct. 2. Cannibalism: Some people believe that the real reason for the extinction of dinosaurs was the result of their cannibalism - carnivorous dinosaurs fed on herbivorous dinosaurs, carnivorous dinosaurs increased, and herbivorous dinosaurs naturally became fewer and fewer, and finally disappeared, and carnivorous dinosaurs killed each other because they had no meat to eat, and finally died together.

3. Climate change theory: As a result of the movement of plates, ocean currents change, which causes huge changes in climate. The cold climate caused the plants to die, and the dinosaurs ran out due to lack of food.

How did dinosaurs go extinct?

Because a large number of dinosaurs have died after an asteroid hit the earth and caused a large number of volcanic eruptions, the air quality and temperature after the volcanic eruption are not suitable for the survival of dinosaurs, so they are extinct.

Anything will go extinct, including humans, and then again, dinosaurs didn't actually go extinct, they evolved, evolved into mammals, classes, and some living fossils of dinosaurs, like crocodiles, lizards, etc.

Dinosaurs lived thousands of years ago, but in our time, dinosaurs mysteriously disappeared, making dinosaurs disappear, it was a comet that hit the earth, causing volcanic eruptions and underground movements, so dinosaurs became extinct after the late Cretaceous period!

Because a huge meteor collided with the earth, a huge heat was formed in the place where it was hit, the impact was very large, the shock wave was enough to make the primeval forest extinct, and then the tsunami brought by the impact, 70 meters, which was the largest ** that led to the death of the vast dinosaur, bringing fatal extinction!

It was killed by a pig, and that story is very long.

With the emergence of angiosperms, dinosaurs couldn't stand the anthocyanins of angiosperms, so that they poisoned the dinosaurs, and it is also said that meteorites hit the earth, and it is possible that a large number of dinosaurs evolved into small animals.

Dinosaurs were a family of large people, and the famous Tyrannosaurus rex was up to 15 meters long from head to tail and 6 meters tall when it stood up. However, the Tyrannosaurus rex was only of medium height. The real "giants" of dinosaurs were sauropod dinosaurs, such as Diplodocus, Brachiosaurus, Malexitisaurus, and Imaginosaurus, all of which were 20 or 30 meters long, and were as tall as a five- or six-story building.

100,000 Whys: Why Did Dinosaurs Go Extinct?

How did dinosaurs go extinct?

It is unable to adapt to the changes in the environment, and is eliminated by nature! They don't want to die themselves!

Very simple! The dinosaurs themselves have already told us how they became extinct?

The first impression of dinosaurs is that they are massive! The sheer size tells us that they eat a lot of food every day, and the food is not grown by the dinosaurs themselves, but depends on the weather. The larger the dinosaurs, the more dependent they are on the climate, which means that they are more and more vulnerable to the natural climate!!

The climate has changed, and the dinosaurs have been eliminated! After the extinction of the dinosaurs, there were no such large land animals on the earth, that is, there was no such climatic environment. Also.

That is to say, after the death of the dinosaurs, the earth has a different climate!!

How did the dinosaur become extinct and obscure?

How did the dinosaur mountain world extinguish the source of the tease split limbs?

There is more than one theory about the extinction of the dinosaurs. The most common saying is the "meteorite impact theory". Huge cosmic disasters, huge meteorites hit the earth, causing tsunamis, **, volcanic eruptions, and the end of the world caused by dust obscuring sunlight.

Some say that the earth underwent a geological orogeny 65 million years ago, because many mountains grew on the flat land, the swamps decreased, and the climate became less humid and warmer. The dinosaur's respiratory organs could not adapt to the cold, dry and hot air, and in winter, the dinosaurs ran out of food, so they went to a dead end.

Some say that the supernova explosion caused a strong change in the Earth's climate, and the temperature suddenly rose and then fell very low. There are also dinosaurs that eat a lot of flowering plants, and there are many toxins in these flowers, and dinosaurs eat a lot of food, so they are poisoned and die.

In short, all kinds of speculations and theories are really varied, and there are no surprises.
