Diplodocus Millions of years ago, the world was a warm, wet place. Tall trees, steamy swamps, and thick bushes covered the grounds Huge creatures called dinosaurs roamed the land. The Diplodocus shown here, was one of the longest dinosaurs. Diplodocus used its tail like a whip to swipe at its enemies. Diplodocus had four sturdy legs to hold up its heavy body. It's a fact! Not all dinosaurs were enormous. A dinosaur called Compsognathus was about the size of a chicken.

几百万年前，地球是一个温暖潮湿的地方。 高大的树木、潮湿的沼泽和茂密的灌木丛覆盖了地面，一种叫做恐龙的巨大生物在陆地上游荡。 这里展示的梁龙是最长的恐龙之一。 梁龙用它的尾巴像鞭子一样猛击敌人。 梁龙有四条强壮的腿来支撑它沉重的身体。 这是事实!不是所有的恐龙都是巨大的。 一种叫做Compsognathus的恐龙和鸡差不多大。

Diplodocus held its long neck out in front of its body. Diplodocus ate large amounts of cycad, fern, and ginkgo leaves with slender peglike teeth. This is a model of a Brachiosaurus another long-necked giant. Unlike most dinosaurs, its front legs were longer than its back legs.

梁龙把它的长脖子伸到身体前面。 梁龙以大量的苏铁、蕨类和银杏叶为食，长着细长如钉子般的牙齿。 这是腕龙的模型另一种长颈巨兽。 与大多数恐龙不同，它的前腿比后腿长。

Allosaurus When fierce Allosaurus came charging through the trees, most other dinosaurs ran for their lives. Allosaurus liked to dine on gentle, plant-eating dinosaurs. It had about 70 jagged teeth for eating meat. Experts find out about dinosaurs by digging up bones. They piece the bones together just like a jigsaw puzzle. Allosaurus's roar probably sounded like a rumble of thunder. It's a fact! Allosaurus had an amazing mouth that opened really wide. This beast could snap up small dinosaurs whole!

当凶猛的异特龙穿过树林冲过来时，大多数恐龙都逃命了。 异特龙喜欢吃温和的食草恐龙。 它有大约70颗锯齿状的牙齿，用来吃肉。 专家们通过挖掘骨头来了解恐龙。 他们把骨头像拼图一样拼在一起。 异特龙的吼声听起来可能像隆隆的雷声。 这是事实!异特龙的嘴张得非常大。 这种猛兽可以把小恐龙整个吃掉!

Allosaurus's huge head was a terrifying sight! Allosaurus walked on two thick, powerful legs. This is the skull of an Allosaurus. Hollow spaces in the skull made the large head of Allosaurus lighter.

异特龙巨大的头是一个可怕的景象!异特龙用两条粗壮有力的腿走路。 这是异特龙的头骨。 头骨上的空洞使异特龙的大头更轻。
