Jurassic World Dinosaur Field Guide is a child-friendly non-fiction guide that uses simple text to describe over 100 dinosaurs. It's basically a rewrite of the 2001 Jurassic Park Dinosaur Field Guide. The book was created by the same authors as the previous dino guide, with paleontologists and Dr. Michael Brett-Surman as writers, and as illustrator. The book is published by Books for Young Readers.
The dates on timelines, at the bottom of most pages, is updated. The start of the Triassic Period is set at 252 million years ago (mya), instead of 251 mya. The Jurassic starts at 201 mya, instead of 200 mya. The Cretaceous starts at 145 mya and ends 66 mya, instead of 144 untill 65 mya.
Spinosaurus is described and portrayed as a semi-aquatic animal with a more horizontal posture.
The "Take Two!" sections, boxes that commented on the animal's appearance in the films are removed or very reduced. There are sections called "The Creatures of Jurassic World!" which only mention that the animal appears in Jurassic World. Often, these sections appear not on the pages that discuss the animal in question, but randomly throughout.
The font on the poster is changed. The name "Shuvuuia" is more readable now.
