Mesozoic Era and Dinosaurs

Mesozoic Era (544 to 245 mya) The age of Reptiles Triassic Period Jurassic Period Cretaceous Period

The Age of Reptiles Dinosaurs roamed the earth New life forms come into existence

Triassic Period (245 to 208 mya) Dinosaurs appeared Began and ended with a mass extinction

Dinosaurs Diapsid Reptiles Archosaurs Pterosaurs Theropods

Jurassic Period (208 to 146 mya) Dinosaurs Ruled Thropods Age of Cycads

Cretaceous Period (146 to 65 mya) Dinosaurs Perished Mammals took center stage Flowering plants provided rich food

Life Forms Conifers Flowering Plants Cycads Deciduous Trees

Mass Extinction Dinosaurs died out End of Cretaceous period
