The mistake I made in buying this book was not reading the reviews first. As you might have read by others, this book is a cheaply made volume with a handfull of blurry, photocopy-quality black-and-white pictures. Even the text is a sort of slap-dash collection of dinosaur related topics without any real coherence. The biggest insult is the price! This book isn't worth more than $5, tops. Take my advice and skip this one.
