Microorganism that the dinosaur lived in the ocean hundreds of millions of years ago originally. The microorganism has evolved gradually
Become the fish. Because there are more and more living beings in the ocean , the fish evolve out two walking on the land to grow again
Kind, then develop out the reptiles. Among them a piece of reptiles turns into the main dragon's subclass.
It has not called definitely (about 65 million years before) from later period to Cretaceous period since the Triassic Period that the dinosaur is one kind
Reptile of main dragon's subclass (Archosauria ) for 140 million years of hegemony land. Dinosaur
Different from other reptiles to enclose limb stand upright under the body when standing, but not spread to the side
. Have evidence show dinosaur may belong to warm blood now. And find that the duck-billed dinosaur builds the room by the nest ,
Prove that the dinosaur breeds young behaviors. There are more than 800 kinds of own dinosaurs that finds at present, at the ground bottom
Kind possibility more.

The word 'dinosaur comes from Greek, which means 'the terrific lizard'.
Dinosaurs were originated billions of years ago, they were micro-organisms living in the ocean. They were gradually evolved into fish.
Due to an increase in living creatures in the ocean, fish was then evolved into amphibians, then into amniotes. A sub-branch of the amniotes became the Archosauria.

As amniotes of the archosauria, dinosaurs dominated the land for up to 140 million years, from the late Triassic period to the late Cretaceous period (approx. (approximately) 65 million years ago).
2007-01-07 11:48:43 補充：
Dinosaurs differed from other amniotes as their limbs are right below the body while standing, unlike other amniotes which have limbs attached to the side of the body.
2007-01-07 11:49:45 補充：
There are sufficient proves nowadays that dinosaurs are probably warm-blooded (不知对不对). It has been discovered that hadrosaurs had extended spaces by their nests,, which proves that they probably raised their own offspring.

Until now, there are more than 800 classes of dinosaurs known to mankind. However, it is highly possible that even more classes existed that are still buried underground.資料來源： to be continued.....need zzzzz

A dinosaur (Dinosaur) word comes from Greek, the meaning is 'terror lizard'.
The dinosaur lives originally from the dozens of hundred million years ago in the sea microorganism. Gradually microorganism evolution
Becomes the fish. Because in the sea biology gradually are many, the fish evolves walks on the land two lives
The kind, then and evolves crawling class. Crawling class then evolves primarily the dragon subclass.
The dinosaur is one kind from the Triassic period later period to the cretaceous period not (approximately 65,000,000 years ago) 絕 up to the name
The tyrant land reaches for 140,000,000 years long time main dragon subclass (Archosauria) reptile. Dinosaur
Different is stands when the appendage stands erect with other reptile under the body, but is not extends sidewise
. Now has the evidence to demonstrate the dinosaur is possibly a warm blood. But discovered the duck mouth dragon builds the room nearby the nest, then
Proved the dinosaur possibly has nurtures young children the behavior. At present oneself discovered the dinosaur has 800 many kinds of, but also in place bottom
The type are possibly more.
