What is a dinosaur?

Dinosaurs were very different from each other reptiles. Some were as small as a chicken and others as large as several planes.

They dominated the world from 60 to 228 million years. As current reptiles, dinosaurs also have a scaly skin.

The first dinosaurs were carnivores, herbivores then appeared.

Carnivorous dinosaurs

Carnivores eat insects, eggs, reptiles and mammals. They were fast hunters. The best was the Tyrannosaurus Rex. The Compsognathus Coelanosaure catching and devouring its prey with its front legs.

With their teeth like daggers, these reptiles were ferocious predators.

Dinosaurs with long necks

The biggest, heaviest and longest animal that ever existed are long-necked sauropod dinosaurs.

These creatures had long tails, compacts, small heads, the front legs shorter than the rear. Fingers clawed inches and wider than the other fingers, allowing them to catch the branches.

In 1986 paleontologists have discovered the bones of a giant sauropod, which would exceed 30 meters.

Amazing dinosaurs

Compared to 150 million years when dinosaurs lived, the 5 million years of human beings are very recent.

Dinosaurs were the strangest and most extraordinary animals of this world. It was sometimes hard to imagine that the Earth has hosted such huge creatures: the first dinosaur fossils, a megalomaniac rus nine meters long, were first taken to the remains of a human giant.

The Brachiosaurus was the heaviest, weighing 80 tons to 23 meters long, with shoulders almost 6 meters high, was as high as a four-storey building!

The smallest, with its meter long and 3.5 kg, Compsognathus was probably one of the smallest dinosaurs.

The fastest, Struthiominus, high and 2 meters long 3 to 4 meters, defended himself by fleeing predators. He was running at over 50 km / h!

The longest neck Mamenchisaurus, with its 22 meters; was almost as long as his cousin Diplodocus, the longest, with its 23 meters with a tail of 14 meters. The most terrible predator was the biggest in the history: Tyrannosaurus, weighing 7 tons, they could reach 14 meters long.

The dinosaurs duckbill

The adrosaures were duck-billed dinosaurs, who were traveling on their front legs to graze.

Adrosaures species were the most common dinosaurs of the Cretaceous. Probably appeared in Central Asia, they were also in Europe and North America. When the climate became drier, they could survivrent because they had a varied diet.
