Cretaceous Era (Part one) : The pinnacle of the dinosaurs reign

The Cretaceous saw the first appearance and initial diversification of flowering plants. Insects and other organisms soon evolve to take advantage of the new food sources and opportunities these plants provide. Conifers continued replacing seed ferns, ginkgos and cycads. This Period saw the emergence of the largest of all known land predators, such as Tyrannosaurus, and the largest flying animal, Quetzalcoatlus. Reptiles dominated the land, the sea and the air. Duck-billed dinosaurs are the commonest ornithischians.
