Causes of death of dinosaurs???? What was the cause of the death of the dinosaurs

As for the cause of death of dinosaurs, the scientific community has still not found a completely correct answer. Popular sayings are as follows.

Meteorite collision theory, climate change theory, volcanic eruption theory, warm-blooded animal theory, cannibalism theory (disproved), mammalian evolution theory, species aging theory, reproductive frustration theory, organosilicon deficiency theory, etc.

It is said to have been caused by a devastating climate change.

I don't know the authoritative, specific explanation.

Dinosaurs disappeared 65 million years ago during the Cretaceous-Tertiary extinction event, along with many other species, including ammonites, cantosauridae, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and primitive mammals [11]. Since the 1970s, there have been many studies that have attempted to explore the causes of this extinction event and have developed several theories.

The usual explanation is that an impact event caused the extinction, with some scientists suggesting other reasons, or a combination of several events that led to the extinction.

The reason for the extinction of dinosaurs has always been a controversy in the scientific community, and an international scientific research chain blind group composed of dozens of experts announced their research results on this matter, pointing out that an asteroid hit the earth off the coast of Mexico 65 million years ago, and the gods caused the earth to have ** and firestorms caused by the impact, the key is to throw tens of billions of tons of material into the atmosphere, blocking the sun's rays, and making many creatures lose their living space, when the dinosaurs were included in the disturbance.

At the same time, the study pointed out that this impact also provided the environment and conditions for the evolution of many new species, including humans.

All kinds of conjectures have arguments, and it is difficult to explain them in one word, please refer to:

The cause of the dinosaur's death is disputed, but the most likely was a meteorite hitting the earth, causing climate change, and the dust on the ground rising to obscure the sun, which led to the dinosaurs' demise.

The most popular and accepted theory is that dinosaurs died when rocks hit the Earth, and then caused a major change in the climate

Meteors fall, volcanoes erupt, and the climate cools.

1. Most people believe that the bumps and sinkings caused by asteroids hitting the earth have made the earth unable to see the sun for several years, resulting in the death of most of the plants and the dinosaurs due to lack of food.

2. Some scientists believe that the earth reached a special period at that time, and all the plants bloomed and then died, and the dinosaurs died of lack of food.

Third, there is also a more unbelievable statement, that is, because there are too many dinosaurs, there are too many farts, which destroys the proportional structure of the air, and the dinosaurs cannot adapt to the environment and die.

There are many theories about the cause of death of dinosaurs, volcanic eruptions, **, parasites, aliens, asteroids hitting the earth, etc., all of which are inconclusive. In short, if you are willing to accept that, accept that, survival of the fittest, survival of the fittest. Perhaps the dinosaurs were not extinct, and some experts believe that birds are the descendants of dinosaurs.

It did not adapt to the global environment at that time.

Survival of the fittest, survival of the fittest.
