Written by paleontologist Dr. Steve Brusatte, this knowledge book invites us to travel to a world lost in the depths of the past many millions of years ago... exploring more than 100 different species of dinosaurs.  A tour through four periods ― the Triassic, Early-Middle Jurassic, Late Jurassic, and Cretaceous ― where we will discover how dinosaurs and other prehistoric animals lived on land, in water, and in the sky.  The large size of the book, which includes notes and a detailed index, combined with the vivid colors from Daniel Chester's illustrations, captivates even the most demanding readers!
