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.
