Welcome to the best application to know the Dinosaurs thanks to the best hd online documentary videos.
Dinosaurs were reptiles that lived in the Jurassic before there were human beings on Earth. They were oviparous, had four legs, and a hard and scaly skin. They inhabited the Earth for more than 150 million years, and then disappeared mysteriously. Among these reptiles were from ferocious murderers to tender herbivores. The dinosaurs presented diverse characteristics that endowed them for survival. The carnivores had sharp teeth and claws adapted for hunting. Some herbivores reached enormous size. Others had natural weapons such as horns.
The two main groups of these reptiles had two different types of hips. There were carnivores and herbivores.
-The lizard-hip saurischia had the pubis forward.
-The bird hip ornithischians were herbivores and had the pubis pointing backwards.
It is believed that the dinosaurs became extinct slowly as a result of environmental changes caused by the withdrawal of shallow seas at the end of the dinosaur era. It is also believed that a huge asteroid hit the Earth in the Yucatan Peninsula, in Mexico about 65 million years ago, or there was also a period of volcanic activity 65 million years ago, over Western India. This activity could have formed a cloud of dust that would hide sunlight. The extinction of the dinosaurs was 65 million years ago, we can now see their skeletons in museums.
