挖掘出来的骨头拼凑出的恐龙骨架揭示了恐龙吃什么、长什么样、如何保护自己等信息。牙齿和嘴的类型展示了它们可能的进食对象,而角展示了其特殊的防御方式。
Fossilized skeletons may also give us the entire picture of what a certain dinosaur looked like. After a dinosaur died, the skeleton remained and was quickly pressed into the rock by some force, such as water or other rock, and then hardened. This is how a fossil is created. Fossils are flat, not three-dimensional, like bones.
化石骨架展示了某种恐龙的外形。恐龙死后,骨架保存下来并被诸如水或其他岩石施加的外力迅速压入岩石然后硬化。这就是化石形成的方式。化石和骨头一样是平的而非立体的。
To date, over 300 types of dinosaurs have been named. Dinosaurs are divided into two main groups according to their hip bones. Some had hips arranged like a bird and some like a lizard. Scientists have named many dinosaurs. Some of the lizard-like dinosaurs are Tyrannosaurus Rex, often known as the T-Rex, who was a meat eater, and Diplodocus, who was a plant eater. All bird-hipped dinosaurs were plant eaters. Iguanodon, Triceratops and Stegosaurus are three of the most famous of this type.
迄今为止,已有超过300种的恐龙被命名。恐龙根据其髋骨分为两大类。有些髋骨构造如同鸟类,有的又如蜥蜴。科学家命名了很多恐龙。一些蜥蜴状的恐龙是霸王龙,经常被称为T-雷克斯,它是肉食性恐龙,而梁龙是草食性恐龙。所有的鸟臀目恐龙是食草恐龙。该类中最有名的三者属禽龙、三角龙、剑龙。
