Article - The evolution of dinosaurs in nature: What do we know about them?
There have been many dinosaurs in nature before in nature. We can find skeletons from them. But who were the dinosaurs? When did they live, and what did they do?
The creation of a living animal and a living human is dependent on mutations through hundreds of years. And the same is the situation for the formation and the evolution of the dinosaurs. Today, we know there have been dinosaurs in nature. And there have been natural selection and evolution for many of them!
The existence of the dinosaurs can be placed back many millions of years in time. Some researchers have found skeleton of dinosaurs being more than 110 million years. The dinosaurs ate carrion and meat. They were big predators and weighed a lot. They lived in the geological periods trias, jura and chalk. They lived in the periods 233 to 66 million before our time! These group of animals included the largest land soils that have lived on our earth! The dinosaurs died during the mass extinction in the chalk and the tertiary period. All of them were then deleted from the globe. The most popular hypothesis is that they were obliterated when an asteroid hit the earth, and that asteroid had a diameter of 10 to 15 km. This place happened nearby the city Progreso in Mexico. The collision led to several volcanic eruptions and several forest fires.
Everybody claims to know who the dinosaurs were. Many know about them, but none of people living on earth today have never seen any of these dinosaurs alive. The dinosaurs were probably widespread around the whole earth, but there have been particularly rich fossil finds in North America, in East Africa and in China! In Norway, we have found remains of the dinosaurs on Andøya, Svalbard and in the North Sea!
The dinosaurs are considered as insects, but they are separated anatomically from other animals the the way they were. We know today what kind of species we had! The way the legs sit on the body is special with the dinosaurs. They were large reptiles, and some draw alternates to the dragons! Some of the dinosaurs lived on land, and some lived in water!
The dinosaurs lived on meat and on plants, and they were from huge to small on four or two legs. Many of the dinosaurs were fossils, and they were approximately 800 species of such. But they were probably many, many more species.
Previously, it has been thought that dinosaurs were slow animals, but that is not true, because some of them could run 30 km/h.
The evolution of the dinosaurs is due to natural selection, and all of their bodies are due to mutations through many, many years in history!
