This is an amazing book with an incredible amount of information. Quality illustrations galore, comparing the size of related species and occasionally modern species. Major illustrations show human figures (or a cat) and scale (1/15, 1/35, etc.) for comparison. Prehistoric feathered birds (non-pterodactyl) are also included. Charts show fossil finds and types, illustrations of eggs, a comprehensive list of known theropods, charts showing speed comparisons between theropods, modern animals (ostrich, cheetah, human), and much more. The reading level makes it accessible to students from mid-grade through college. Should appeal to dinophiles of all ages, science geeks, time travel theorists, fiction and nonfiction authors, readers of Prehistoric Times magazine, and anyone interested in digging beyond the Jurassic Park film franchise. Looking forward to the companion book on sauropods later in 2020.
