Dinosaur Era (时代)
We know that prehistoric (史前的) animals once lived on Earth because of their fossils. Fossils are the remains of animals and plants（1） that lived millions of years ago. The largest known dinosaur is the largest land animal that has ever been found. Its name is Seismosaurus（地震龙）, and from its head to the end of its tail (2), it measured 120-150 feet. Seismosaurus was a plant eater and would not have been dangerous –unless it stepped on （3）you, for it weighed about 10 tons. Dinosaurs were reptiles (爬行动物), but very different from today’s reptiles. Many were giant-sized, and armed with ferocious（凶恶的） teeth and savage horns. Above them, great pterosaurs（翼龙） swooped（4）through the air on leathery（5）wings. The dinosaurs and pterosaurs ruled the Earth from about 200 million years ago until they died out about 65 million years ago. Many dinosaurs, including the biggest of all, Diplodocus（梁龙）, lived only plants. Others were flesh eaters and hunted the plant-eating dinosaurs.
