      Age of the dinosaurs to survive    

    The heyday of dinosaurs was in the Jurassic, belonging to the mid-Mesozoic. Continental crust generated the Atlantic on the slit. Africa began to split from South America, and India was ready to shift to Asia.

Biological Overview:

【Jurassic - Age of Dinosaurs】
   Jurassic was the heyday of dinosaurs; the dinosaur has quickly become the ruler of the planet, all kinds of dinosaurs gather together and formed a world of strange and fantastic dragons. In addition to the huge Brontosaurus, Diplodocus and so on, the flying fish, pterosaurs in the water also had a lot of development and evolution.

【Creature on land】
    The main herbivorous vertebrates are the original dinosaur-legged dinosaurs and birds head dinosaurs, and similar reptiles like small mammal. But in the later period, great dinonaur-legged dinosaurs dominated in quantity. These animals can eat both high and low lying plants; Long-legged dinosaurs relied mainly on swallowing the stones to grind food.

    Large theropod predators grazing animals; and small theropods, such as empty bone dinasaus and ??small jaw bone dinosaurs hunt small prey and also may feed on carrion

    Insects had greater diversification in the age of Jurassic. More than one thousand kinds of insects lived in the forest, lakes and marshes in the vicinity. In addition to the already emerged cockroaches, dragonflies, beetles, there were grubs class, tree ticks, flies and moth class. The vast majority of these insects continued to survive to the modern time.

    In the plant communities in the Jurassic, the cycad class, pine and cypress class and ginkgo class of gymnosperm were extremely prosperous. Wood thief class, ferns and dense pine of ferns and cypress and ginkgo trees and lush fern formed forests together. Herbal and other grass fern classes were all over the lower land, covering on the ground. In those relatively dry area, growing the cycads and fern type, forming a broad evergreen wilderness.

【Creature in the sky】
    With the pterosaur wing, the cortex was superiority in the air. Early birds were also appeared and the most notably was the terrorsaur, which had a similar bone skeleton, teeth and claws with small theropod, but there were long wings with feather and tail and it could fly.

    The emergence of bird was another important event in the evolution of vertebrates. In 1861, the "Archeopteryx (Archaeopteryx)" fossils that discovered in late Jurassic stratum in Solnhofen, Bavaria, Germany, were recognized as the representative of the oldest bird; In recent years, Chinese paleontologists discovered Sinosauropteryx fossils, which has received widespread concern in the international academic community and provided a new and important material for the study of the origin of feathers and birds and its evolution.

【Creatures in the sea】
    Pseudo dinosaur classes and panel teeth dinosaur class become extinct, but the fish dinosaurs survived, in the animals living in shallow sea, a group of them has evolved into sea crocodile of fin-shaped limb and bony fish. There were also other marine life like snake neck dinosaurs and short dinosaurs. In the late period, the crocodile fish and sea crocodylidae gradually became
