During the 170 million years from the late Triassic Period to the late Cretaceous Period, an extraordinary group of animals, called the dinosaurs, dominated the Earth. Some were small, but others were gigantic. Some ate only plants and had long necks, and others had sharp .
Currently we are increasingly wellinformed about dinosaurs because of the findings of paleontologists, who study the fossilized teeth and bones of these animals. Sometime during the late Cretaceous Period, dinosaurs disappeared from the face of the planet in an event known as the K-T extinction event. Some attribute the dinosaurs' disappearance to the impact of
a large meteorite with the Earth. In this chapter, you will find very detailed illustrations of these prehistoric creatures.
