Some were so large that the ground shook as they walked. At the same time, other kinds of giant reptiles swam and hunted in the ocean. Some were even bigger and more powerful than the dinosaurs. In this book, you’ll read about eight of these real-life sea monsters. Luckily, they aren’t around anymore. These giant sea reptiles didn’t just live with the dinosaurs—they also died out with them. 4 1630_OceanMonsters_FNL.indd 4 5/1/08 3:53:21 PM Some kinds of dinosaurs ate meat. Others ate plants. All giant sea reptiles, however, were meat-eaters that hunted other animals for food. 5 1630_OceanMonsters_FNL.indd 5 5/1/08 2:48:03 PM Ichthyosaurus How big was it? How do you say it? What does it mean? ik-thee-oh-SOR-uhss fi sh reptile Ichthyosaurus was shaped like a fish and lived in the water. Yet this sea animal was a reptile—not a fish. How was Ichthyosaurus different from a fish? All fish are able to breathe underwater. Ichthyosaurus, like all sea reptiles, could not breathe this way. Instead, it stuck its head above the water every few minutes to breathe air. 6 1630_OceanMonsters_FNL.indd 6 5/5/08 12:38:48 PM Fish use body parts called gills to breathe underwater. Ichthyosaurus and all other sea reptiles that lived with dinosaurs used body parts called lungs to breathe air. 7 1630_OceanMonsters_FNL.indd 7 5/1/08 2:48:37 PM Index breathing 6–7 fossils 9, 18, 22 Nothosaurus 20–21, 22 dinosaurs 4–5, 20 Ichthyosaurus 6–7, 20, 22 Ophthalmosaurus 12–13, 22 Elasmosaurus 10–11, 22 Kronosaurus 14–15, 22 pterosaurs 19 eyes 12, 14 Liopleurodon 16–17, 22 tail 8–9 fish 6–7, 8, 10, 12, 19 Mosasaurus 8–9, 20, 22 Tylosaurus 18–19, 22 flippers 8–9, 20 neck 10–11 Read More Brown, Charlotte Lewis.
