What are some of the Triasic organisms?

The Triassical period, which extends 251 to 199 million years ago, is the first geological period of the mesozoic era. During the trias, most of the country of the country was locked on a supercontinent known as Panga. The interiors of the continent were huge, dry deserts, while swamps and forests circled the edges. Triassic was a warm and dry time, without evidence of posting. In fact, the poles were moist and warm, the perfect climate for reptiles.

Triassic began immediately after the worst mass extinction the country has ever seen, the Permian-Triassic EXTICTION event. 96% of all marine species and 70% of all types of earthly vertebrates were killed in 10,000 years or less. This event was so extreme that many paleontologists are called "great dying". It is assumed that this was due to a combination of factors, especially extreme and continuous volcanic eruptions known today as a "trap". Trilobites, Eupterids (Sea Scorpions), Blastoids (ancient echidnoderm),Trilobites, facing fish and armored fish (placodermy) completely disappeared. Ammonity, a cephalopod superficially similar to modern nautilus, almost disappeared, but one line survived and diversified. Several types of corals disappeared. All the great amphibians died on Earth and created space for diversification reptiles and synappers, the first relatives of mammals. In general, almost all large herbivores bit dust, requires that the largest amount of healthy leaves survive.

Although the greatest amphibians died, many medium amphibians survived because the extinction on Earth was obviously not as extreme as the sea demise. The amphibian class called Temnosponyls has been successful all the time. Permia, however, is also the only known mass extinction of insects, with many mesozoic fossil groups of insects is significantly different from paleozoic groups.

The most important evolutionary event Triassic was pRogesive takeover of terrestrial ecosystems of Plasimi, especially the menacing archosaurs - today represented birds and crocodiles - which would develop into real dinosaurs around the end of the period. The reptiles initially competed against Synapsids, which dominated the former Permian, then basically won over them and competed only against each other. For hundreds of millions of years, synappers would be included in the shadows of large reptiles, just to appear again 65 million years ago, after the extinction of K-T. This progressive event that occurred around the middle trias is known as the "Triassic takeover".

Changing the life of animals from the previous and during the Triassic is so extreme that one of the Thread Division EE in geological periods with multicellular life - paleozoic - are listed at the beginning of the period.
