有没有关于恐龙的英语介绍？越多越好What is a Dinosaur? Millions of years ago, long before there were any people, there were dinosaurs. Dinosaurs were one of several kinds of prehistoric reptiles that lived ring the Mesozoic Era, the "Age of Reptiles." Dinosaurs were reptiles and most hatched from eggs. No dinosaurs could fly and none lived in the water. Plant-eating sauropods were the largest animals to ever walk on Earth - but blue whales are more massive than any of the dinosaurs were! The largest dinosaurs were over 100 feet (30 m) long and up to 50 feet (15 m) tall (like Argentinosaurus, Seismosaurus, Ultrasauros, Brachiosaurus, and Supersaurus). The smallest dinosaurs, like Compsognathus, were about the size of a chicken. Most dinosaurs were in-between. It is very difficult to figure out how the dinosaurs sounded, how they behaved, how they mated, what color they were, or even how to tell whether a fossil was male or female. http://www.google.cn/search?client=aff-9991&channel=link&hl=zh-CN&q=dinosaur+&btnG=Google+%E6%90%9C%E7%B4%A2&meta=lr%3Dlang_en Dinosaurs were vertebrate animals that dominated terrestrial ecosystems for over 160 million years, first appearing approximately 230 million years ago. At the end of the Cretaceous Period, 65 million years ago, dinosaurs succumbed to a catastrophic extinction, which ended their dominance on land. Taxonomists consider modern birds to be the direct descendants of theropod dinosaurs. Since the first dinosaur was recognized in the 19th century, mounted, fossilized dinosaur skeletons have become major attractions at museums around the world. Dinosaurs have become a part of world culture and remain consistently popular among children and alts alike. They have been featured in best-selling books and films such as Jurassic Park, and new discoveries are regularly covered by the media. The term dinosaur is sometimes used informally to describe other prehistoric reptiles, such as the pelycosaur Dimetrodon, the winged pterosaurs and the aquatic ichthyosaurs, plesiosaurs and mosasaurs, although technically none of these were dinosaurs.
