Africa shared the supercontinent's relatively uniform fauna which was dominated by theropods, prosauropods and primitive ornithischians by the close of the Triassic period.

TRIASSIC Some reptiles, frogs, turtles and crocodiles existed earlier, but dinosaurs didn’t appear until late in the Triassic period. The period marked the rise of small, lightly built dinosaurs. The first mammals evolved during the Triassic period. Most of the plants that existed were evergreens.

Pterosaurs (flying reptiles) also made their first appearance here as well as frogs, turtles, and crocodiles. During the Late Triassic period, many small mammals also arose.

Pangaea, Gondwanaland, Laurasia and Tethys The world geography was not dominated by Pangaea for all time before the end of the Paleozoic. The Earth's plates had probably clumped up more than once in he past and moved apart before clumping up again. That cycle of clumping and reopening of oceans is called the Wilson Cycle.

Triassic period â pine trees and pterodactyls During the Triassic period (about 248 to 199 million years ago), most of Earth's land continued to stick together in one big supercontinent, Pangaea.Because the middle of Pangaea was so far from the oceans, it was very dry there, like a desert.

History of Earth's Climate 3. - Mesozoic Mesozoic Era. The Mesozoic geological era consists of three geological periods, namely Triassic, Jurassic and Cretaceous. The Triassic period (245 to 210 million years ago) paved the way for the Dinosaurs' reign on earth and the formation of the giant continent called Pangaea occurred during the same period. Then came the Jurassic period (210 to 146 million years ago) which saw the complete domination of the Dinosaurs on earth.

It was after this that dinosaurs really started to radiate and diversify.

Learn About the Different Dinosaur Periods At the start of the Triassic period, 250 million years ago, the earth was just recovering from the Permian/Triassic Extinction, which witnessed the demise of over two-thirds of all land-dwelling species and a whopping 95 percent of ocean-dwelling species.

Permian-Triassic Extinction Of the five or so mass extinctions recorded in Earth's fossils, this one at the end of the Permian period and the start of the Triassic was the most catastrophic. More than half of the families of living things died out, and as many as 90 to 96 percent of the planet's marine species were lost.At the same time, perhaps 70 percent of the land's reptile, amphibian, insect, and plants species went extinct.he Permian layers contain abundant animal fossils and fossilized traces of animals, while the Triassic layers are almost devoid of fossils, suggesting a mass extinction event occurred 250 million years ago, at the end of the Permian.

- Triassic Period. The Triassic Period, first of the Mesozoic Era's three periods, began about 240 million years ago and lasted for approximately 40 million years. It was preceded by the great Permian-Triassic mass extinction, which destroyed over 90% of living species.riassic. The Triassic period is the first of the three divisions of the Mesozoic era, which is known as The Age of Reptiles.. The period lasted for 37 million years, from 245 to 208 million years ago. The Triassic is named after a tricolor sequence of red, white and brown rock layers found in Germany.

Mesozoic Era Paleobiology Triassic Period (245 to 208 mya) (Triassic Fossils) The Permian-Triassic (P/T) Extinction Event marked the end of the Permian Period of the Paleozoic Era, and the start of the Triassic Period of the Mesozoic Era. The P/T extinction decimated the brachiopods, corals, echinoderms, mollusks, and other invertebrates.

- Click here to download. The start of the Triassic period (and the Mesozoic era) was a desolate time in Earth's history. Something—a bout of violent volcanic eruptions, climate change, or perhaps a fatal run-in with a comet or asteroid—had triggered the extinction of more than 90 percent of Earth's species.

Triassic Period By the start of the Triassic, all the Earth's landmasses had coalesced to form Pangaea, a supercontinent shaped like a giant C that straddled the Equator and extended toward the Poles. Almost as soon as the supercontinent formed, it started to come undone.

- The Triassic Period. In many ways, the Triassic, lasting from 251.0 mya to 199.6 mya,* was a time of transition. It was at this time that the world-continent of Pangea existed, altering global climate and ocean circulation.ectonics and paleoclimate. As with almost any other period of the Earth's history, the Triassic had a unique climate and biota indigenous to that time. The paleoclimate was influenced largely by tectonic events that never existed before or since.

A Time When Beasts Ruled the Earth The Jurassic period started 200 m.y.a and ended 145 m.y.a meaning it lasted 55 million years. At the beginning of the jurassic period the Earth’s continents were still all jammed together which formed the supercontinent of Pangaea. They were beginning to drift apart though. Several new seas were being formed due to the continents drifting apart.
