Dinosaurs Floating

Modern science divides the history of our Earth ' s development into four eras. The Mosaic era (which began 230 million years ago and lasted 163 million years) will be of particular interest to us. It is in this period of time that the dominant position on Earth among the living world has taken dinosaurs, which, by the end of the same mesosaic era, were completely extinct. So who are these dinosaurs and why didn't they reach our days?
Dinosaurs represented the largest abundance (or even class) of ancient presumptives on Earth about 100 million years before the beginning of the mesosis era. Like all the presumptuous, dinosaurs were in the vertebral animal class, breathing lungs. The temperature of the dinosaur body was not constant, it depended on ambient temperature. The skin of dinosaurs for mechanical protection and protection against drying was covered with horns. In order to multiply the dinosaur males, several eggs covered by the leather sheath (such as modern crocodiles and turtles) were placed in the Earth's nest.
In the mesosaic era, dinosaurs were completely dominated by land, water and air. The dinosaurs included both grassy and dynamo-like units. Since the ancestors of modern mammals that have just appeared in the mesosaic era have been thousands smaller than giant mocks, they did not represent any competition for dinosaurs. But this situation has also had a negative side: all food chains in predatory dinosaurs have been completely locked inside the dinosaurs. This means that the food base for damsy dinosaurs represented only huge grassy dinosaurs, which in turn nutrients and coastal algae.
