Fearsome Albertosaurus

With its huge head, rows of pointed teeth, and sharp claws, Albertosaurus was so scary. Tag along with a group of Albertosaurus on a hunt, then meet Styracosaurus, with its horn-rimmed neck frill; Gallimimus, one of the fastest dinosaurs; a crafty predator called Alectrosaurus; Polacanthus, a timid plant-eater with spiked back; and Lambeosaurus, a large, fast-running duck-billed plant-eater.
