This book tells the story of the Velociraptor, a lightweight dinosaur who used its speed to catch prey. It was only three feet (one meter) tall, but was feared for its ferocious hunting ability.

This book tells the story of the mighty Tyrannosaurus, which lived during the Cretaceous period between 140 and 65 million years ago. This ferocious dinosaur was one of the largest meat eaters, growing up to 40 feet (12 meters) in length. Its head was huge and full of long, sharp teeth.
This book tells the story of Tylosaurus, which swam in the prehistoric seas between 87 and 82 million years ago. It was a fierce marine reptile that used its sharp teeth and huge jaws to feed on sharks and other marine reptiles, such as plesiosaurs, as well as fish. A Tylosaurus could grow as long as 50 feet (15 meters) and was a superb swimmer.
This book tells the story of Triceratops, a dinosaur that was heavier than a present-day elephant with three large horns on its head and a neck frill.

This book tells the story of Stegosaurus, who lived during the Jurassic period between 155 and 145 million years ago. It had large bony plates, which it probably used for temperature control, soaking up the sun, or catching a cool breeze.
This book tells the story of Spinosaurus, a dinosaur with large jaws, sharp teeth, and a huge sail on its back that stood six feet (two meters) tall.

This book tells the story of the powerfully built Sabre-tooth Tiger who stalked the land more than 10,000 years ago. It was like no cat living today. At the front of its jaw grew two long, curved canine teeth that resembled two sharp sabres. A fierce predator, it used these long teeth to pierce the flesh of its prey.
This book tells the story of Pteranodon. During the late Cretaceous period, between 89 and 80 million years ago, one of the largest flying reptiles to exist flew in the skies. Its large wingspan and short tail made it very agile so it could turn or dive quickly. Its head could measure nearly six feet (two meters) long and on the back of its head grew a magnificent crest.
This book tells the story of Parasaurolophus, who lived 76 to 74 million years ago during the Cretaceous period. It belonged to a group called hadrosaurs, or duck-billed dinosaurs, named after their flat beak. Parasaurolophus had a long crest that swept back over its head. The crest was hollow, and Parasaurolophus probably used it to make deep honking sounds.
This book tells the story of the enormous Apatosaurus, who lived during the late Jurassic period between 170 and 140 million years ago.
