Age range 5+Tyrannosaurus, a fearsome hunter, had strong back legs that allowed it to run at speed, colossally powerful jaws, and rows of dagger dagger-like teeth. It was, however, just one dinosaur among many. This book also includes Vulcanodon, a big plant plant-eater with a whip-like tail; heavily armoured Sauropelta; horned Pentaceratops; Kentrosaurus with plates and spikes; and tiny, feathered Avimimus.
