What are some Jurassic animals?

The Jurassic period spread about 200 to 146 million years ago. The Jurassic period was right in the middle of the "age of reptiles", also known as the "age of dinosaurs". In the late Triassic, immediately before Jurassic, almost all important dinosaur groups developed-Thheropods (which include all carnivorous dinosaurs), Sauropods (long herbivores who contributed during Jurossic during Jura) and proportionate to herbivors as . Other non -inconsistent reptiles also evolved in the late trias, including pliosaurs (sea reptiles) and pterosaurs (large winged reptiles).

Jurassic was immediately before the age of flowering plants, so the landscape was dominated by conifers, cycads and ferns. Cycady, tropical trees with a strong suitcase, have experienced their greatest success during the Jurassic period, and even today many intuitively recognize these plants as "common at the time of dinosaurs". Unlike the quitting triassic in front of him, or today's cold Cellozoic, Jurassic was fresh and warm, including higher altitudes wherethe forests spread to the poles. This climate was extremely encouraging at that time.

At the beginning of Jurassic, dinosaurs have already ruled the country for about 30 million years. There were two main groups: Saurischians (Dinosaurs with a hoarse on lizards) and Ornithischians (dinosaurs with a bird). The Saurischians included Theopods (all carnivores) and Sauropods (the largest herbivores). Ornithischians included a number of other herbivores of medium to large, albeit all smaller than most sauropods. In fact, confusing birds developed in the late Jurassic of dinosaurs with a lizard. In the example of parallel development, they gained significant hips of birds.

Jurassic ecosystems, SU, were dominated by various large therapy as Carnivore Allosaurus , which had the same body plan as Tyrannosaurus rex , which did not develop until 90 million years later. The largest of this kind reached a length of 12 m (39 ft) and paThey were among the most frightening ground carnivores of all time. No earthly carnivore closer today.

Jurassic is considered the golden age of sauropods, huge dinosaurs with long throat, who used their height to eat from the highest trees. Many sauropods were so volume and size that they were not just afraid of the largest predators, such as allosaurus . One late jurassic sauropod, SuperSaurus , was up to 34 m (112 ft) in length and weight up to 40 tons.
