Triassic

  1. 1. Triassic By
  2. 2. Some information about the Triassic -This was the period that came to light early mammals the first dinosaurs - The significance of Triassic is tri-meaning three, which is why the three layers of rock that were deposited during the period of the Earth.
  3. 3. Some information about the Triassic - The Triassic Period, which lasted from 245208000000 years, was the first of the three periods in which dinosaurs lived. It was divided into two subperiods: the lower and upper. The Triassic lasted from 245-232000000 years, and Upper Triassic from 231, about the time the dinosaurs appeared, to 208 million.
  4. 4. Plants of Triassic The Triassic period (248 - 206 million years ago) followed the biggest mass extinction in the history of the Earth, the Permian extinction. This left the Earth relatively unpoplated (especially the seas) and ready for new life. During the Triassic period, the first dinosaurs and the first mammals appeared. Many plant families were culled; giant club mosses and horsetails also went extinct during the late Permian, and new forms evolved during the Triassic. The Triassic was the beginning of a boom in conifers and cycadophytes.
  5. 5. Mammals in the Triassic The dinosaurs dominated the Earth's surface during this period mainly due to the sudden disappearance of most mammal-like reptiles genres. However, they were some of these kinds of mammal-like reptiles, that over again Triassic diversification, thus playing an important role in the emergence of true mammals, which evolved from these reptile-mammals in the late Triassic.
  6. 6. Flying animals in the Triassic The Triassic air environment was dominated by several small winged reptiles that made short flights from tree to tree. The wings of these little feathered winged reptiles they lacked feathers but were formed by a membranous tissue that was to develop into the late Triassic onset of the pterosaurs, a large group of flying reptiles that were already capable of performing certain duration flights.
  7. 7. Aquatic animals in the Triassic In the aquatic environment, highlighting the molluscs, which experienced a dramatic recovery after near annihilation in the Permian, and highlighted including ammonoids. Other groups of marine organisms were less effective at diversification, but in the late Triassic begin to appear some groups of aquatic reptiles, among which the nothosaurs, the Placodontes and ichthyosaurs.
