What was the Triaska period?
The Triassical period is the first period of the mesozoic era that lasted about 180 million years. Mesozoic means "medium life", time between ancient paleozoic and a modern cordinating. The trias themselves were about 251 to 199 million years ago. The exact cause of the extinction of Permian-Triassic is unknown, but it was so devastating that biologists informally call it "great dying".
During the triassical period, the world was defined by one supercontinent, pangea and one super-meter, panthassa. In the center of Panga, there was a gigantic desert, the largest the country has ever seen. The general climate everywhere was very hot and dry and represented a challenge for Colonizataion.
The oceans first appeared modern corals that continued their huge activities for building reefs, which during Silurian stopped almost 150 million years before. Ammonity flourished and diversified from a single line that survived a great dying. A number of fish and reptiles similar to reptiles, including ichthyosaurs, flourished at sea at seaUrs and many others. At the end of the Triassical period, some of them, especially ichthyosaurs, developed on proportions of the size of dinosaurs. Echinodermy evolved in the sea.
on Earth were Plazim's real winners in the Triassical period and the rest of the mesozoic. Therefore, Mesoika is often called the "age of reptiles". Indeed, modern insects such as dragonflies have first evolved into trias. Among the dinosaurs, archosauromorf (cold -blooded) was the most flourished, above their endothermal (warm bloded, mammalism similar) relatives, probably because cold -blooded reptiles have better adapted to the dry environment. The big continent of Panga was mostly desert, seen oasis and a thin ring of coastal life.
swamp trees and ferns of paleozoic, which led to the largest coal bed on the ground, required a prosperut moisture and therefore did not do so during a dry trias. In the forests of the Triassical period dominated in theYzely, such as conifers and other gymnosperms.
