Paleontologist Robert T. Bakker tells the amazing story of a day in the life of a pack of Deinonychus
(a.k.a.“raptor”) dinosaurs. Readers follow the creatures as they single out, kill, and devour an injured tenontosaur; climb up into a tree; fall asleep; and are themselves stalked by a giant predator. Includes an explanation of how scientists study rocks and minerals; fossil roots, claws, teeth, and bones; and modern predators to understand raptor behavior.
