- Late Cretaceous Epoch (100.5-66 MYA) - Second half of the Cretaceous. The last epoch of the dinosaurs and one of its greatest. In Asiamerica, Duck billed, Ankylosaurids, horned, Tyrannosaurs, Pachycephalosaurids, and Dromaeosaurs were present. Gondwanaland had different dinosaurs, including Abelisaurs and Titanosaurs. Birds began to replace Pterosaurs in the air. Didelphid marsupials and placental mammals diversified but were still small. In the sea, mososaurs, modern sharks, and polycotylid pliosaurs appeared. Long necked elasmosaurs diversified, while Ichthyosaurs went extinct. An explosion of flowering plant species occurred at the beginning.
