THE JURASSIC PERIOD, the middle part of the Mesozoic era, lasted from 208 to 146 million years ago. During Jurassic times, the land -mass of Pangaea broke up into the continents of Gondwanaland and Laurasia , and sea levels rose, flooding area of lower land. The Jurassic climate was warm and moist . plants such as ginkgos, horsetails and conifers thrived and giant redwood tree appeared , as did the first flowering plants. The abundance of plant food coincided with the proliferation of herbivorous (plant-eating) dinosaurs, such as the large sauropods (eg. Diplodocus) and stegosaurs (eg.Stegosaurus). Carnivorous (Flesh-eating) dinosaurs, such as Compsognathus and Allosaurus, also flourished by hunting the many animals that existed-among them other dinosaurs. Further Jurassic animals included shrew-like mammels, and pterosaurs (flying reptiles) as well as plesiosaurs and ichthyosaurs (both marine reptiles)
