This book retains its legs even after all these years. There are a couple of illustrations that show (white) people looking at fossils, and there is one that shows suburban tract houses to suggest "where did the dinosaurs go?" However, the book consists primarily of watercolors of big lizards. It exlains that no one really knows what happens to the dinosaurs to cause their extinction, which is not all that informative but allows for a Q-and-A on developments in paleontology since 1959.
It's a safe book that shows big lizards, and I'd estimate early elementary text. ( )
