A portrait gallery of baby dinos and dino cousins. Going straight for the "AWWWW" reaction from viewers, O'Brien poses 11 big-eyed, usually fuzzy prehistoric hatchlings on plain white backgrounds in front of huge, slightly blurred parental legs that extend past the page tops. He doesn't stint on the factual load, either. Along with identifying labels, each creature comes with an informative one- or two-sentence comment, such as, for the stegosaurus ("roofed lizard"): "This pint-sized critter grew into a leaf-eater that had a body the size of an elephant but a brain the size of a meatball." Just for reference, a plate of meatballs is placed temptingly in front of the little stego.and all the rest of the dino tykes likewise come with either food (notably a box of doughnuts being thoroughly mangled by a tiny triceratops) or plastic toys ranging from a rubber ducky delighting a dinky Anatotitan ("giant duck") to a race car zooming past a trio of downy velociraptors ("swift thief"). A baby T. rex ("tyrant lizard king") gazing out sweetly, ensconced in a comparatively huge crown, is an especially adorable addition.

Following a set of additional descriptive notes at the end, budding dino-fans will find silhouettes of the babies lined up on a comparative size chart--with a four-foot-tall human child towering commandingly over all. Awwwwesomely cute. -- Kirkus Reviews.
