简要介绍
Brief introduction

所有恐龙已经灭绝，但是恐龙的后代——鸟类存活下来，并繁衍至今。
All dinosaurs extinct, but the dinosaur offspring - birds survival, and grew so far.

恐龙（英文：dinosaur英音['dainəsɔ:]美音['daɪnə,sɔr]）是生活在距今大约2亿3 恐龙
Dinosaurs (English: dinosaur British sound [' dain ə s ɔ:] the beautiful sound [' da ɪ n ə, s ɔ r]) live in is about 2 million dating three dinosaurs

500万年至6595万年前的、能以后肢支撑身体直立行走的一类陆生动物，是群中生代的多样化优势脊椎动物，大多数属于陆生（栖息在陆地上）的爬行动物，但能直立行走，支配全球陆地生态系统超过一亿六千万年之久。
500 million years to 6595 million years ago, to support the body's upright hind legs, is a kind of terrestrial species of Mesozoic diversification of the advantages of vertebrates, most belong to terrestrial (perched on land) reptile, but can walk upright, dominate global terrestrial ecosystems more than 160 millions of years.

说是脊椎动物而不说是爬行动物的原因是，恐龙曾经被归为爬行动物，但是其不符合爬行动物的基本特征之一：匍匐的行走方式，以及现在一直被质疑的冷血动物一说。
Say vertebrates and not saying of reptiles reason is that dinosaurs to be categorized as reptiles, but it does not conform to the reptile one of the basic characteristics: prostrate walking style, and now has been questioned the cold-blooded animal said.

Dinosaurs were reptiles that lived through three periods of Earth's geologic history: Triassic (208-245 million years ago), Jurassic (145-208 million years ago), and Cretaceous (65-145 million years ago). Different species of dinosaurs flourished and then became extinct throughout these three periods.

All dinosaurs were reptiles, but not all reptiles were dinosaurs. Even though the name "dinosaur" means "terrible lizard," dinosaurs were not lizards at all.

Some Key Dinosaur Facts

All dinosaurs had four limbs. Some walked on all four legs; others, on their two back legs.

Dinosaur legs were positioned below their bodies, making it possible for them to walk upright.
Lizard legs are positioned outward from their bodies, giving them a sprawling posture.

Dinosaur legs were positioned under their bodies. They were able to walk and run very efficiently.

Dinosaurs lived on land. They did not fly in the air or live in water.

Some dinosaurs were carnivores (meat-eaters), but most were herbivores (plant-eaters).

Not all dinosaurs were large. The smallest, Compsognathus, was about 3 feet long (1 m). One of the largest, Barosaurus, reached 80 feet (24 m). Tyrannosaurus rex measured 46 feet (14 m).
