What Is Meant By Impressive Armoury When Talking About Dinosaurs

Did some dinosaurs | A migrate?

| A Some people think that herds of Pachyrhinosaurus used to trek about 2,200 miles (3,500 km) from northern Alaska to Canada each autumn to escape the cold, dark winters. The herds would have returned to Alaska to feed on the lush plants that grew there in the spring.

Did sauropods live together?

Evidence suggests that many types of plant-eating dinosaurs, including sauropods such as Barosaurus, lived together in herds. Being part of a group usually gives an individual animal greater protection against predators. It is also possible that sauropods were sociable animals. A herd may have contained a number of family groups that roamed the countryside together.

More Facts

Sauropods were more comfortable in forest habitats because the trees shaded their huge bodies from the Sun.

Leaellynasaura lived within the Antarctic Circle, where there was little sunlight in winter. Experts believe the dinosaur must have been warmblooded to survive the dark and cold.

Did plant-eaters ever live in trees?

| A When fossils of the ornithopod Hypsilophodon were discovered in 1849, paleontologists believed that this small plant-eater lived in trees. They thought it used its long tail for balancing while it clung onto branches with its sharp toes. Now experts are convinced that none of the plant-eaters lived in trees, although some of the smaller meat-eaters may have been tree-dwellers.

hadrosaurs (sometimes called duck-billed dinosaurs) have been discovered in rocks that were laid down in swamps. People once supposed that the hadrosaurs fed on water plants that grew in swamps, like the modern North American moose. Experts now believe hadrosaurs spent most of their time on dry land.

Among the first dinosaur fossils to be studied were those of the plant-eater Iguanodon.

How did plant-eaters fight back?

To defend themselves against predators, the different plant-eating dinosaurs developed an impressive armory of weapons. The ankylosaur Euoplocephalus had a ball of thickened bone at the end of its tail, which it could swing at attackers. The stegosaurs had tails studded with daggerlike spikes for stabbing attackers, while the sauropods' size was their main defense. Some dinosaurs had features that puzzle paleontologists, because it is unclear whether they were weapons or merely tools for feeding.
