Introduction

Greetings young reader! Today we are going to take a step back in time and enter the age of the dinosaurs. The dinosaurs are an extinct species of animal that began to live on the Earth over 200 million years ago. “Extinct” means that they no longer exist. The dinosaurs are some of the most intriguing and awe-inspiring animals that have existed on our planet. The dinosaurs’ colossal size, strange characteristics, and mysterious disappearance make them inherently worthy of study and interest. Even more than these reasons, the study of dinosaurs itself is an incredible adventure which requires thought and imagination. The study of dinosaurs helps you to appreciate just how mysterious and amazing life and nature really is. Our planet supports not only us and the animals that live today, but it even supported creatures as gigantic and strange as the dinosaurs- just think how cool that is! I hope that you bring a spirit of openness and wonder to your study of the dinosaurs, and that you come to appreciate the mystery and value of the dinosaurs.

The animal we are learning about today is called the Sarcosuchus. The Sarcosuchus is closely related to the dinosaurs, but it is not defined by scientists as a dinosaur. It is defined as a proto-crocodile. The Sarcosuchus is fun to learn about because it is one of the largest crocodiles to have ever lived. In this book we are going to learn about the appearance, behavior, and environment of the Sarcosuchus as well as about the dinosaurs it lived with. We know what we know about the dinosaurs from a variety of sources including fossils, biology, and other scientific disciplines. Fossils are the ancient remains of the dinosaurs, the most familiar being their bones. Biological science is the study of life in general, but many scientists compare the dinosaurs to modern day animals to support their theories.

Before a talk about dinosaurs can take place it is important that we discuss the theory of evolution. Evolutionary theory supposes that all the animals we know and see today are the direct descendants of animals that existed millions of years ago. The dinosaurs and other creatures that existed millions of years ago either died out or gradually changed into different animals. For instance, birds are considered to be surviving dinosaurs because their dinosaur ancestors survived the dinosaur extinction event (we will discuss this later). The crocodiles are the modern descendants of the ancient Sarcosuchus.
