All about Dinasours

The word Dinosaur means "Terrible Lizard". The Dinosaurs are now gone but we still see their footprints, their poop and their skeletal remains.

The people who study about dinosaurs and their remains are called "Paleontologists".

Not all Dinosaurs have vanished as birds we see today are actually dinosaurs. They are the descendants of a type of a dinosaur called "therapods", such as Giganotosaurus, Tyrannosaurus rex, Troodon and such other dinosaurs. The Dinosaurs lived in the time period called as Triassic, Jurassic and Cretaceous.

First lets visit the Triassic period when there were no flowers and only small plants and that period looked very dull. Triassic period then changed to Jurassic. Jurassic period had little bit of flowers, low life herbs and ferns. It was hot and red during this period. Jurassic period then changed to Cretaceous period. During this period we had all kinds of flower, big, small, short and tall. At that time we also had flying creatures called Pteranodon. They were called Therasaurs related closely to dinosaurs.

At the end of this period, human beings started to appear. Paleontologists still do not know how the dinosaurs vanished. One of the ideas is that an asteroid hit the Earth and made the plants die making all the herbivorous dinosaurs to vanish.The carnivore dinosaurs could not find enough food and they died too.
