4: Plants The Jurassic period was the time when enormous sauropods lived, devouring tremendous amounts of foliage each day. What's interesting about the Jurassic period plant life is that no one knew major of plant life evolved during this period. At the beginning of the Jurassic period, the earth saw the disappearance of sped-ferns floras. The many smaller and medium-sized dinosaurs that lived during this time, like Xiaosarus and Stegosaurus would have browsed on low -lying plants, like seed-ferns, ferns, and horsetails. Land plants abounded in the Jurassic, but floras were different from what we see today. Although Jurassic dinosaurs are sometimes drawn with palm trees, there were no palm trees in the Jurassic period.
6: Animals During the Jurassic period, the largest land animals of all were around. These huge animals were known as sauropods. There were also rodents, no longer than rats, that roamed in the foliage, and there were a number of early mammals. The Apotosarus is one of the biggest mammals to walk on earth; it is known for its long neck and its long, whipped-like tail as well as its small skull. In the seas, the fish like Ichthyosaurus and giant marine crocodiles swam. There were also Cephalopods, relatives of squids. Jurassic Cephalopods included the Ammonites, with their external shells. The first bird that appeared was the Archaeopteryx. Now, there are many fossils bearing unmistakable imprints of their feathers.
8: Climates At the beginning of the Jurassic, the earth's continents were still jammed together, forming the huge continent Pangaea. Gradually these continents began to drift apart. The climate began to warm as Pangaea broke apart. The ocean currents could now flow around each individual continent, moderating the climate and providing shallow marine habitats. By the late Jurassic, the climate was warm and tropical with lush vegetation. No glaciers were present at the poles. Sea levels were high due to the lack of polar glaciers. Despite of the Breakup of Pangaea, by the late Jurassic the distribution of many animals and plants were more widespread. The early Jurassic period also brought a much warmer and wetter rain forest.
