Is the mystery of dinosaur extinction solved? Dinosaur extinction truth

Location: Yucatan Peninsula, Mexico.

Character: A 10-kilometer-sized meteorite (equivalent to the flight altitude of a jetliner) Plot: It crashes headlong into the sea at a speed of 40 kilometers per second, and then sets off a tsunami of up to 5 kilometers, which triggers a powerful volcanic eruption in the Deccan Plateau and changes the direction of the Earth's tectonic plates.

Tsunamis swept across every inch of the Earth's surface, filling the sky with volcanic ash. The earth has entered a low temperature due to the lack of sunlight all year round, ending a great era in the history of biology.

Large plants could not survive the Ice Age, large herbivores became extinct, and then carnivores became extinct, but small animals, insects needed less nutrients and consumed less energy to survive, and dinosaurs were cold-blooded animals, and they had to rely on the right external temperature to maintain blood circulation, and the arrival of the Ice Age was the reason for the extinction of dinosaurs, which explains why dinosaurs died out quickly, and primitive species could not survive severe climate change, which is the same reason that primitive people could not withstand the cold before they entered the fire age But there's also a problem, which is why the dinosaur species in the deep sea died out at the same time, and the oceans were much longer than the land, but they didn't change much, and the Ice Age had the least impact on the deep-sea species, but the deep-sea species went extinct at the same time, and there's a question of whether there were bioepochs.

The jury is still out.

So far, meteorite theory has been dominant, but other theories cannot be denied.

Overall, the extinction of the dinosaurs was due to a sea change in the environment.

The cause of the extinction of the dinosaurs is still being studied. For a long time, the most authoritative view was that we all have it? No, it doesn't. And where do these skills go? There is only one explanation:,

An asteroid hits the Earth, the Earth's crust moves volcanoes erupt, and volcanic ash blocks the sun's rays, causing the Earth to cool and plants to die in large numbers. Large herbivorous carnivores die.

There is no evidence, in fact, it is all blind guessing.

Basically, this conclusion can be drawn with scientific evidence.

Actually artificial, Slav not only created the Tunguska Great**, but also created and used the time machine to travel back to ancient times and exterminate the dinosaurs, just like the plot of the Terminator movie, which was later destroyed in the fire of the laboratory.

The !! who was killed by the landlord o( o for sure

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.

The dinosaurs that existed in reality were 200 million years ago, when there were no human beings. Do you know why the dinosaurs were wiped out? Dinosaur extinction refers to the Cretaceous mass extinction event that occurred at the end of the Mesozoic Era in the Cretaceous period, about 65 million years ago.

The main reason is the survival of the fittest.
