Introduction

The Age of Dinosaurs lasted for most of the Mesozoic era (meaning ‘Middle Life’), from 252 to 65 million years ago. And what an age it was! Among those huge reptiles were the biggest, strongest, fiercest killers ever to walk the Earth. They had to be, because their victims were even more massive, some as big as houses! All of these dinosaur predators belonged to the group called theropods, which means ‘beast feet’. But not all theropods were huge. Some were tiny, smaller than a pet cat. Yet they were also extremely ferocious and deadly for their size. Hundreds of kinds of theropods came and went through the Age of Dinosaurs. They lived all over the world. They hunted a wide variety of prey, from little bugs and worms, to their closest dinosaur cousins, the immense, long-necked, longtailed sauropods. The following pages explain the science behind the most fearsome, deadly predators ever to prowl our planet.
