(ORDO NEWS) — Scientists from different countries conducted excavations in the desert of the Junggar Basin, located in the northwestern part of China.
Fossils were found there, which became evidence that in fact dinosaurs were not heat-loving creatures and lived in the cold.
For a long time it was assumed that dinosaurs lived exclusively in subtropical conditions, where it was warm and there was a lot of moisture. This was indicated by the fossils that researchers found in Africa and South America.
Also, everyone knows about the theory that says that the cause of the death of dinosaurs was the fall of a huge asteroid.
The space object caused such a large amount of dust to rise into the air that for many years it did not settle on the surface of the earth.
This, in turn, provoked climate change, the temperature dropped sharply, so many dinosaurs disappeared, because they could not adapt to new living conditions.
The latest research by experts has shown that this theory is not correct. In fact, dinosaurs at the very beginning of their existence were as frost-resistant as possible, which allowed them to be the masters of the planet for almost 150 million years.
Evidence of the new version was found in fine-grained sandstone and siltstone formations that were at the bottom of the ancient lakes of the Dzhungar basin.
The deposits were formed about 206 million years ago, when the Triassic period was ending. It was then that the mass extinction of the dinosaurs happened, the causes of which have not yet been determined exactly.
The Dzungarian basin is located beyond the Arctic Circle. The deposits indicate that over 200 million years ago there were very severe frosts in this region.
When the researchers were studying the coastline of the lakes, they were able to find footprints of dinosaurs, which surprised them very much.
Also, scientists found a lot of pebbles, the diameter of which was about 1.5 centimeters. They stressed that it should not be far from the coastline.
The only explanation for this is that the pebbles are fragments of huge pieces of ice that could have formed on the shore, and then gradually slid into the lake.
This indicates that the Dzungarian Basin was regularly covered with a layer of ice, but in such a climate, the dinosaurs felt great.
