Opis

The Middle and Late Jurassic periods saw the largest land animals ever to walk the Earth--the sauropods, along with predatory dinosaurs and plated and armored herbivores. At the other end of the size scale, some small meat-eating dinosaurs developed powered flight and gave rise to birds. This fully illustrated book also examines the scientific view of dinosaurs as living creatures. Once considered docile and inactive--like their distant cold-blooded reptile relatives--dinosaurs are now thought to have been active, energetic creatures that used a variety of methods to maintain a constant body temperature.
