Permian Period: Climate, Animals & Plants The Permian Period was the final period of the Paleozoic Era. Lasting from 299 million to 251 million years ago, it followed the Carboniferous Period and preceded the Triassic Period. By the early Permian, the two great continents of the Paleozoic, Gondwana and Euramerica, had collided to form the supercontinent Pangaea.

Jurassic The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. The start of the period is marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Late Pliensbachian/Early Toarcian event in the Early Jurassic, and the Late Tithonian event at the end; however, neither event ranks among the 'Big Five' mass extinctions.

Permian-Triassic Extinction The 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.

Cretaceous Period Cretaceous Period. Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided). The Cretaceous is the longest period of the Phanerozoic Eon.

Mesozoic Era: Age of the Dinosaurs Credit: Carl Buell. During the Mesozoic, or Middle Life Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs. Boundaries

Triassic The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it would take well into the middle of the period for life to recover its former diversity. Therapsids and archosaurs were the chief terrestrial vertebrates during this time.o coal deposits date from the start of the Triassic period. This is known as the coal gap and can be seen as part of the Permian–Triassic extinction event. Sharp drops in sea level at the time of the Permo Triassic boundary may be the proper explanation for the coal gap.

- Online exhibits : Geologic time scale : Mesozoic Era. The Cretaceous Period. The Cretaceous is usually noted for being the last portion of the Age of Dinosaurs, but that does not mean that new kinds of dinosaurs did not appear then. It is during the Cretaceous that the first ceratopsian and pachycepalosaurid dinosaurs appeared.

The Mesozoic Era The Age of Dinosaurs Life Recovers From The Permian Extinctions. It took most of the first and second periods of the Mesozoic, the Triassic and the Jurassic periods, for the diversity of species to recover and achieve some balance.

Geology chapter 19 The Permian period lasted from 299 to 251 million years ago* and was the last period of the Paleozoic Era. The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth.

- The Mesozoic Era. The Mesozoic Era is divided into three time periods: the Triassic (251-199.6 million years ago), the Jurassic (199.6-145.5 million years ago), and the Cretaceous (145.5-65.5 million years ago).*. Mesozoic means middle animals, and is the time during which the world fauna changed drastically from that which had been seen in the Paleozoic.

- The Mesozoic Era includes the Triassic, Jurassic, and Cretaceous Periods and is characterized by the development of flying reptiles, birds, and flowering plants and by the appearance and extinction of dinosaurs. See Table at geologic time.

Carboniferous The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period 358.9 million years ago , to the beginning of the Permian Period, 298.9 Mya. The name Carboniferous means coal-bearing and derives from the Latin words carbō (coal) and ferō (I bear, I carry), and was coined by geologists William Conybeare and William Phillips in 1822.

The Geologic Time Scale An era of geologic time, from the end of the Precambrian to the beginning of the Mesozoic. The word Paleozoic is from Greek and means old life. Permian (286 - 248 million years ago) The final period of the Paleozoic era.It is named after the province of Perm, Russia, where rocks of this age were first studied.ver time, life forms change. Their fossil record allows geologists to date and compare rocks across geological time. For example, dinosaur fossils are only found during the Mesozoic era some 245 to 65 million years ago. The following table shows the geologic time scale.

Permian The Permian is a geologic period and system which extends from 298.9 ± 0.15 to 252.17 ± 0.06 million years ago. It is the last period of the Paleozoic, following the Carboniferous and preceding the Triassic of the Mesozoic.he Permian ended with the most extensive extinction event recorded in paleontology: the Permian-Triassic extinction event. 90% to 95% of marine species became extinct, as well as 70% of all land organisms. It is also the only known mass extinction of insects.

Mesozoic Era: Age of the Dinosaurs The Mesozoic Era began roughly around the time of the end-Permian extinction, which wiped out 96 percent of marine life and 70 percent of all terrestrial species on the planet. Life slowly rebounded, eventually giving way to a flourishing diversity of animals, from massive lizards to monstrous dinosaurs.

The Triassic Period: Reptiles Inherit The Earth The Mesozoic Era is divided into three periods: the Triassic Period, the Jurassic Period, , and the Cretaceous Period. The Triassic began around 248 million years ago, after the mass extinction that brought an end to the Permian Period. It lasted about 42 million years.eptiles Inherit The Earth. The Triassic Period is the first period of the Mesozoic Era. The great extinction at the end of the Permian period had brought the end to 90% of the living species on Earth. The Triassic was a time of growing new species to repopulate the planet.

- Carboniferous, the the fifth period of the Palaeozoic era, between the Devonian and Permian periods. The Carboniferous lasted from about 363 to 290 million years ago. During this time the first reptiles and seed-bearing plants appeared, and there were extensive coral reefs and coal-forming swamp forests.

- View full size image. The Cretaceous Period was the last and longest segment of the Mesozoic Era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic Period about 145.5 million years ago to the Cretaceous-Paleogene (K-Pg) extinction event dated at 65.5 million years ago. In the early Cretaceous, the continents were in very different positions than they are today.

- 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.
