When Pangaea split about 200 million years ago, Gondwana began its own isolated journey and gradual break-up into the landmasses we know today – Australia, South America, Africa, India, Madagascar, Antarctica and New Zealand. Mesozoic (Smithsonian Institution) The world during the Mesozoic Era was a place both foreign and yet familiar when compared to Earth today.

Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era.248 to 206 Million Years Ago. In many ways, the Triassic was a time of transition. It was at this time that the world-continent of Pangaea existed, altering global climate and ocean circulation. The Triassic also follows the largest extinction event in the history of life, and so is a time when the survivors of that event spread and recolonized.Dinosaur communities were separated by both time and geography. The 'Age of Dinosaurs' (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods. Gymnosperms expanded in the Mesozoic era (about 240 million years ago), supplanting ferns in the landscape, and reaching their greatest diversity during this time. It has been suggested that during the mid-Mesozoic era, pollination of some extinct groups of gymnosperms was performed by extinct species of scorpionflies that had a specialized ...The Mesozoic Era (252 to 66 million years ago) The MesozoiJul 28, 2022 · The Mesozoic Era was the third of the three eras of Online exhibits: Geologic time scale: Mesozoic Era.
