Dinosaurs diverged from their archosaur ancestors during the middle to late Triassic period, roughly 20 million years after the Permian&;ndash;Triassic extinction event wiped out an estimated 95% of all life on Earth.
Little children idolize Dinosaurs especially little boys as they enjoy the ferocity of the monsters and the little boys enjoy playing make believe when the dinosaurs fight with each other.
Types of Dinosaurs:
There are two main types of Dinosaurs: saurischia and ornithischia.
The lizard-hipped Dinosaurs ‘saurischians’, which comes from the Greek for ‘lizard hip joint’.
The bird-like hips are named ‘ornithischians’, which comes from the Greek for ‘bird hip joint’.
