The mystery of dinosaur extinction

We humans have lived on the earth for two or three million years, and this history should be said to be not short. Are you afraid of oxime? Na？ Wu Han Ceci Ran? Blame the emperor for burning cloth? nbsp

In the Mesozoic era, the earth was once a world dominated by dinosaurs, and dinosaurs could be found everywhere in both plain forests and swamps. They lived on the earth for1.300 million years, but somehow, the dinosaurs became extinct, and they all disappeared from the earth forever. This is really an eternal mystery.

For more than a hundred years, I don't know how many scientists have tried to uncover the secret of dinosaur childlessness, but they have never been able to justify themselves. With the mutual penetration of natural sciences, some new theories about dinosaur extinction have appeared in recent years.

Some scientists believe that the extinction of dinosaurs was due to the cold climate. At the end of the Cretaceous period 65 million years ago, the world was cold on a large scale, the daily temperature difference increased, and the hot and cold seasons alternated obviously. Dinosaurs used to living in tropical environment could not hibernate like snakes and lizards, nor could they hide in caves to avoid the cold like fur animals. Dinosaurs are warm-blooded animals. They have no appearance and physiological function to resist cold, and they can't resist and adapt to cold attacks. Finally, they are ruthlessly eliminated by nature.

Some scientists assert that the extinction of dinosaurs was the result of crustal movement. About 70 million years ago, there was a strong crustal movement on the earth, which caused some basins to rise and shallow hills to appear, thus causing water and forests to dry up. At the same time, the seabed changed, the sea level dropped by more than 300 meters, the land between Asia and North America began to connect, a large number of animals moved to dinosaur habitats, and food supply was difficult, which made dinosaurs in a state of "food shortage" and gradually died of severe hunger.

Some scientists also suggested that the extinction of dinosaurs was caused by the collision and explosion of stars. In the late Cretaceous, an asteroid with a diameter of about 10 km collided violently with the earth. The impact speed is about 6.5438+10,000 kilometers per hour. During the impact, amazing dust was raised. Dust floats in the atmosphere, even blocking sunlight, making the earth dark for a period of time, the temperature drops, the photosynthesis of plants stops, plants wither, the "food chain" is interrupted, and dinosaurs die one after another.

Other scientists speculate that dinosaurs were poisoned by flowering plants and died out. Dinosaurs lived in Mesozoic, and gymnosperms such as ferns, cycads, ginkgo biloba and conifers dominated the plant kingdom. There are many tannins in these plants, which are harmless to dinosaurs. However, the earliest flowering plants appeared1.200 million years ago. These flowering plants often contain strong alkaloids, which adversely affect the physiology of dinosaurs. Some alkaloids, such as brucine, are very toxic. Dinosaurs swallowed a lot of alkaloids, and the toxin reaction led to serious physiological disorders and death.

The extinction of dinosaurs was due to interspecific competition and intraspecific competition-this is the understanding of other scientists. The activities of one organism often directly or indirectly endanger the survival of another organism, so there is direct or indirect competition, which is called "interspecific competition". For example, meat, competition between animals and herbivores, and competition between animals. In the age of dinosaurs, carnivores with strong reproductive ability and developed brains appeared. They ate many eggs laid by dinosaurs, which led to the death of dinosaurs. Dinosaur eggs were found in Inner Mongolia, Shandong and Guangdong. In particular, Shixing County in northern Guangdong Province found the largest and best preserved dinosaur eggs in the world, with 34 and 35 eggs in a nest respectively, and found the existing dinosaur fossils. In order to survive, creatures of the same species attack each other and devour each other, which is called "intraspecific competition". Tyrannosaurus rex, for example, is a Tyrannosaurus rex in the dinosaur family. Its head is 1.5 meters long, and its jaw has sharp teeth, so it can devour other herbivorous dinosaurs at will. Dinosaurs can be divided into herbivores and carnivores, and they are very long, both of which are more than 20 meters. For example, dinosaurs found in the United States were 27 meters long, and Mamenxilong found in Sichuan, China was 22 meters long and weighed 40 to 50 tons. Dinosaurs about the size of roosters were found in Luban, China, but they were counted as two. This phenomenon of "everything has its vanquisher, the law of the jungle" led to the final extinction of dinosaurs.

Although all the above statements have some truth, each statement can't be justified and can't be fully affirmed by the scientific community. For example, "dinosaurs ate flowering plants and became extinct", then pterosaurs in the air and ichthyosaurs in the water didn't eat flowering plants on land at all, so why did they become extinct at the same time as other dinosaurs? But hadrosaurs, ceratosaurus and other groups are more prosperous after flowering plants appear? In a word, the mysteries in the evolutionary history of these creatures have not been completely uncovered so far.

1926 crystal carving was found in the Mayan civilization site in Honduras.

Take that part of your chin off,

Touch the wishing tree from the bottom and your eyes will glow.

Although from an anatomical point of view, it is generally correct to shape a human skull,

But the fineness of the close occlusion of dentition is really amazing.

There is another magical method:

Some teeth are obviously cut by rotating tools.

So this exquisite handicraft can be integrated up and down,

At that time, rotating tools could not exist anyway.

This makes the mystery of the crystal skull more confusing.

3. Planes in Mayan culture

It is a relic of the flourishing ぇたシェヌ culture that existed in South America from 500 to 800 AD.

This ornament with a length of 6cm, a width of 5cm and a height of 1.5cm was excavated.

It is a pendant used by the royal family and is regarded as an "animal form" eye.

The original text of this sentence is "the image of an animal", and I can't translate it well. I hope people who can understand can say so. )

However, zoologists have not found any similarities among various animals with known forms.

So I entrusted the analysis to an expert in aviation mechanics:

Results The nose, cockpit, main wing, fuselage, vertical tail and horizontal tail should be complete.

The shape and balance completely conform to the theory of aviation mechanics,

So this ornament is called "Golden Space Shuttle".

There are many unsolved mysteries in the world, at least thousands of which have been passed down to this day and are being studied. For example, the mystery of aliens living in seclusion on the earth, various forms of whispers (UFOs), UFOs in secret bases of the US military, unidentified troops in World War II, crop circles, Bender incident, the mystery of alien bases on the back of the moon, unidentified diving objects, Loch Ness monster, savage mystery, Bermuda Devil's Triangle, Tunguska Big Bang, Nazi treasure mystery, Stonehenge in Britain, and mysterious thousands of coffins in Rob Desert 3000 years ago.
