Millions of years ago, and long before people appeared on this planet, one of the strangest creatures ruled the Earth-dinosaur.Dinosaurs are one of the most durable creatures ever.
Some dinosaurs were unhealthy and ate plants. Others were ruthless hunters with sharp teeth: when they caught their victims, they sputtered them with their razor-like teeth before they began to quench their flesh.
Separate reptiles
All dinosaurs were reptiles. They lived in land and most were giving eggs to thick shell. They had nails and hard skin, all scales Reptiles can not adjust from by themselves the temperature of their body. They have to wait for them to warm up or get them the air that surrounds them starts. Some scientists now support that some dinosaurs were "warm-blooded" - that they could produce with their body the warmth, that this it was needed, as the Mammals do.
So what did the dinosaurs from the other reptiles differ? Their legs began just below their trunk and were not glued to the side like the legs of the rest of the reptiles. They could walk and move much easier than the other reptiles that had to drag their bodies to the ground, which made the move very difficult. Dinosaurs they walked in a much more upright attitude either to two or four legs. Some were moving too late, but some could run extremely fast.The legs of the dinosaurs were straight and upright. The legs of other reptiles are biawev from oblique.
What is reptilian ?
Today's reptile is: lizards, crocodiles ,the oligarchs, snakes, sea and land turtles. The reptile does not have a "central system Heating ". They can not regulate the Heat of their body. as can Mammals , people. If the air is cold, their blood is cold as well. Av is hot. then it's hot and their blood.
Giants and nano.
Some dinosaurs were giant. If they lived today, they could look over a four-story building. There were dinosaurs long like four buses. Others again. was one with the ground. Some were so small that they could fit into a human palm.
IS NOT DINOSAUR
The pterosaurs, flying reptiles, were not dinosaurs. Dinosaurs. they did not fly.
Neither are the close relatives, the huge reptiles who swim that are they were dinosaurs. They lived in the sea, while the dinosaurs lived on the shore.
The reptile skin: From fossil prints
we know that the dinosaurs had skin with scales. It resembled the skin of modern reptiles.
