The first thing a young dinosaur expert needs to know about Pteranodon is that it isn't a dinosaur! It's a flying reptile that lived during the time of the dinosaurs. The creature's wingspan is much wider than any modern bird's wingspan--and its wings were attached to a finger on each hand. This incredible carnivorous reptile likely soared for hundreds of miles over water. Pteranodon's most fascinating facts are showcased in this accessible text, which uses graphic elements such as labeled pictures and maps to reinforce key points. A concluding activity asks readers to spot the reptile in a prehistoric scene.

Iguanodon got its name because its discoverer thought its teeth looked like the teeth of an iguana--but much bigger! This plant-eating reptile was just the second dinosaur ever discovered. Scientists have learned a lot about Iguanodon since then. Besides presenting many fascinating facts about the big creature, this volume provides valuable information about Earth at the time of the dinosaurs as well as how paleontologists figure out how dinosaurs looked and lived. Readers will gain a better understanding of the prehistoric world through the many fossil photographs, Iguanodon images, and graphic elements--including a final fun activity.

Brachiosaurus means "arm lizard" because this reptile (not lizard!) had longer front legs than back legs. But when readers see the spectacular images featured in this book, they'll be much more impressed by the dinosaur's very, very long neck. They'll also learn about scientists' evolving understanding of how Brachiosaurus lived, including what this plant eater ate and how much (hint: a lot!). Significant science concepts are presented using at-level vocabulary and visual elements throughout the text, such as maps and labeled pictures, which are especially helpful to visual learners.

Allosaurus was a large dinosaur that lived during the Late Jurassic Period, more than 145 million years ago. This carnivore, with its sharp teeth and hooked claws, was a terror to its prey. Readers of this enlightening volume will learn where these meat eaters roamed, what they hunted, and how their terrifying teeth compared to the teeth of the mighty T. rex! Well-organized and appealing information in tables, maps, and images will aid young paleontologists in their understanding of this reptile as well as the environment in which it lived.
