In the scientific world, a real sensation: some scientists are sure that man lived with dinosaurs in the Mesozoic era. Moreover, dinosaurs are the ancestors of ancient humans.
Approximately 70 million years ago, our planet was inhabited by strange lizards that lived in forests, seas and lakes, rushed through the air. They lived on all continents, and their number reached millions. It is believed that dinosaurs were huge, but in fact there were small individuals among them, the growth of which did not exceed the size of a rabbit. Of course, there were real giants, reaching a body mass of about 70 tons and 27 meters in length. Most of them walked on four limbs, although there were some who moved on two legs, while leaning on a powerful tail. They ate not only meat, but also ate tons of grass.
Dinosaurs dominated the world for 135 million years. If you believe the generally accepted scientific opinion, they had no competitors on the planet, because there were no large mammals, no birds, and even less a man at that time. All ecological niches were occupied by dinosaurs. However, with the end of the Cretaceous period and the Mesozoic era, something incredible happened - all dinosaurs also disappeared: large and small, land and waterfowl, flying. However, they did not leave offspring. Of the many orders of reptiles that existed in the Mesozoic era, only a few survived to the present - lizards, crocodiles, turtles, snakes.
The extinction of dinosaurs happened on all continents at the same time. Most of all, the disappearance of marine reptiles raises questions, since they could not have any enemies: aquatic mammals appeared much later. Sea lizards were quite mobile, mainly feeding on fish. They, according to experts, were sufficiently protected from any geological, climatic and environmental disasters.
Of course, the extinction of the dinosaurs did not happen in one day, but by geological standards it was a very short period. In Central Asia, the so-called death fields are known, where huge accumulations of dinosaur bones - millions of individuals - stretch over long stretches. The burials contained not only bones of old lizards, but also of young animals. This, according to experts, indicates that they died as a result of some kind of sudden catastrophe.
After the extinction of dinosaurs, mammals received more than just living space. There was a real evolutionary outbreak in the development of this class of animals. The planet, freed from dinosaurs, was gradually filled with animals that combine the characteristics of many groups of mammals that exist in our time. These are herbivores with sharp claws and fangs, predators with hooves, huge animals and several rows of horns. And only after millions of years, as a result of natural selection and the change of a large number of generations, only those animals that were most adapted to certain living conditions developed. At the final stage of development of one of such surviving groups of mammals - primates - a man appeared who was gifted with the ability to think. After a while, he began to wonder why,Are dinosaurs actually extinct?
Some paleontologists are convinced that the main reason is competition, and mammals ousted dinosaurs. True, scientists do not specify how they, small and few, managed to do this. Of course, mammals had a higher level of development of the nervous system, but this still does not mean anything, because if you follow this logic, then only the most highly developed animals would live on the planet now. Thus, this theory is not confirmed.
Other scientific theories operate on climatic and geological factors. According to the supporters of these hypotheses, during the Mesozoic period there were no high mountains, and the main element of the landscape was swampy lowlands. The climate was mild enough. The end of the Cretaceous period was marked by a change in the planet's climate and its relief, vegetation changed. Dinosaurs died out due to climatic changes (either from a cold snap, or from overheating), or they simply did not manage to adapt to the new plant foods. However, this hypothesis is also untenable, because physical and geographical changes on the planet occurred regularly, and if we talk about the supposed cooling at the junction of the Mesozoic and Cenozoic, then geologists did not find any signs of this.

The essence of another scientific theory is that dinosaurs became extinct due to a cosmic catastrophe, in particular, from a nearby supernova explosion. During such outbreaks, a huge amount of gamma rays hit the Earth, destructive to dinosaurs and other animals.
There are many other, no less interesting theories of the great extinction of ancient lizards, in particular, epidemics, excessive specialization of the organism, other animals eating dinosaur eggs, and the reorientation of the planet's magnetic field. But they all try to explain the disappearance of the dinosaurs by some one factor, which could not be all-encompassing.
The Spanish merchant V. Julsrud in 1945, driving near the city of Acambaro, discovered a place full of ancient clay products. In total, by 1952, about 30 thousand of such figurines were collected, sculpted from baked clay. They depicted not only people, but also animals, including dinosaurs. In the scientific world, they started talking about a fake collection, but additional research helped establish their exact age, which reached 2.5 thousand years BC.
Similar images of dinosaurs are found on the famous collection of "black stones of Ica", consisting of 15 thousand stones. Its discoverer L. Cabrera was accused of falsification, but it was later established that the first such stones were discovered in the 19th century.
But who, then, could have seen the dinosaurs, which became extinct long before the supposed appearance of man? Who managed to portray them so accurately? The age of these figurines has been established, but dinosaurs no longer existed 2.5-4 thousand years ago. All this made it possible for scientists to suggest that these accumulations of stones and figurines are stone libraries collected by the ancient inhabitants of Central and South America. And they are most likely copies of older originals that have not survived to this day. But then who is the author of the original?
There are many other interesting findings that can shed light on this problem. In particular, in the state of Texas, in the bed of the Palaxy River, clear fossilized dinosaur footprints were found, next to which were the prints of human feet. Moreover, it is likely that humans were chasing this dinosaur.
The American paleontologist K. N. Dougherty managed to establish that in the so-called "Valley of the Giants" there are more than one hundred paw prints of different types of dinosaurs - and there are always human footprints next to them …
But the tracks in Texas are far from the only ones. For example, in 1931, the American geologist G. Burru reported on the discovery of human footprints in layers that reached 250 million years old. He managed to find such traces near Mount Vernon. But after all, at that distant time, not only mammals, but also dinosaurs did not exist. This could not be a fake, because the photographs clearly show the structure of sandstone, on which traces were imprinted.
Thus, there are several explanations for these sensational findings. The first version - an unknown group of forgers for decades have been faking numerous images and footprints in order to amaze the world of science. The second hypothesis is even more fantastic, but nevertheless …
But what if we assume that the roots of humanity stretch much further into the past than even the most daring experts can imagine? And if indeed man lived at the same time as dinosaurs?
Relatively recently, dinosaur tracks were found in Uzbekistan. But most of these traces were found on the territory of Turkmenistan. The chains of tracks were of various lengths and directions. There were also parallel tracks. And among these footprints, the researchers managed to find the imprint of a bare human foot, or rather, the foot of a humanoid creature. It is very early to draw any conclusions at the present time, and it is extremely dangerous to build hypotheses on the basis of single tracks. But on the other hand, it is also impossible to dismiss the theory that man descended from dinosaurs, just like the version that primitive people were responsible for the death of dinosaurs. There are also more fantastic assumptions, the essence of which boils down to the fact that if a person in ancient times could not descend from dinosaurs and could not appear by himself,then he flew from another planet. Thus, the found footprints are the prints of aliens.
Undoubtedly, it all looks too fantastic. And scientists themselves are not in a hurry to categorically declare that the prints they found are traces of an ancient man. There is still a lot of unknown in the world that scientists cannot find a rational explanation for. And the mystery of the origin of man seems to be among them …
