The reason why dinosaurs killed each other, the real reason for the extinction of dinosaurs?

There are contradictions in everything, and there are opposing and unified sides.

Cannibalism??? It was a carnivorous dinosaur that killed a herbivorous dinosaur.

The extinction of the dinosaurs was caused by the impact of a huge asteroid on the Earth 65 million years ago, which caused a huge amount of dust to obscure the sky and the sun, causing global climate change and the death of a large number of animals and plants, and the dinosaurs were not spared.

There are many hypotheses about the extinction of dinosaurs, including climate change, species struggle, continental drift, geomagnetic change, plant poisoning, acid rain and meteorite impact, as well as orogeny, volcanic eruption, species aging and other hypotheses.

The reason is very simple, it can't adapt to the changes of the earth, natural selection, and survival of the fittest.

Planetary impacts.

The cause of the extinction of the dinosaurs is still being studied. For a long time, there was an authoritative opinion that the extinction of the dinosaurs was related to a large meteorite 65 million years ago.

According to research, there was an asteroid with a diameter of 7-10 kilometers that fell on the surface of the earth, causing a large **, throwing a large amount of dust into the atmosphere, forming a dust fog that obscured the sky and the sun, causing the photosynthesis of plants to temporarily stop, and the dinosaurs became extinct.

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. The hypothesis that an asteroid hits the earth: an asteroid hits the earth, causing a large amount of dust to obscure the earth's atmosphere, causing animals to freeze or starve to death at that time. (the more common way of saying it is now).

2. Volcanic eruption hypothesis: At the end of the Cretaceous period, there was a volcanic eruption, and the violent volcanic activity sprayed a large amount of volcanic ash, sulfate, and carbon dioxide into the atmosphere, blocking the sunlight, and the climate was cold, which caused the dinosaurs to perish.

3. Climate change hypothesis: the Jurassic humid and hot, almost perennial temperature remained unchanged until the Cretaceous global natural environment deteriorated, the climate seasonality was obvious, the temperature difference between day and night became larger, and the warm and humid climate zone gradually shrank, leading to the extinction of the dinosaurs.

4. Food poisoning or scarcity hypothesis: In the late Cretaceous period, plants were replaced, so that dinosaurs could not eliminate plant toxins in the process of changing food, resulting in their death. At the same time, it is not excluded that the dinosaur population is less fertile due to lack of food to reduce the pressure on the population.

5. Ocean change hypothesis: Since the middle of the Cretaceous, the separation and drift of continental plates have accelerated significantly, the ocean circulation has become more complex, and the crustal movement has intensified, causing the sea to retreat and the temperature to rise, leading to the extinction of the dinosaurs.

2l is talking about the asteroid hitting the Earth hypothesis, however, it is not the asteroid that "hits" the Gulf of Mexico, but "crashes out" of the Gulf of Mexico.

Have a great time!

It is currently believed that the asteroid hit the Earth to change its living environment.

The extinction of the dinosaurs caused by the impact of an asteroid on the earth!
