A group of reptiles called the dinosaurs were a terror on the land. there were many sorts of dinosaurs. Some were only as big as cats. Others were the size of jumbo jets. Some dinosaurs were meat – eaters, while others ate only plants.
Other huge reptiles swam in the oceans. Plesiosaurs had long, snake – like necks and feet shaped like paddles. Another group of reptiles, the pterosaurs, soared through the skies on skin – covered wings.
