I decided this book because it gives every dinosaur and marine mammal through every era and it gave very detailed illustrations along with tons of info.
The Complete Guide to Prehistoric Life
By Tim Haines
The most exciting view of prehistoric life.
"Comprehensive, illustrated encyclopedia to prehistoric animals... lifelike detail... this easily readable book should appeal to dinosaur enthusiasts of all ages."
-Science News
At the heart of the book are 350 richly detailed and lifelike color illustrations -- accompanied by comprehensive text -- which are the result of pioneering work by the Emmy award-winning creative team at Framestore CFC. Using animation, graphic effects and filmmaking, they recreated awe-inspiring prehistoric creatures and the world they lived in. These images are now reproduced to thrill readers.
The Complete Guide to Prehistoric Life was published to accompany two BBC TV prime-time programs, Life Before Dinosaurs and Walking with Life, both part of the Discovery Channel's award-winning Walking with Dinosaurs series.
