The Permian-Triassic (P-Tr) Extinction Event is widely recognised as the greatest extinction event on Earth. It is also known as the "Great Dieing".
It occurred 251 million years ago marking the end of the Permian Period and the start of the Triassic Period.It also marks the end of the Paleozoic Era and the start of the Mesozoic Era. Estimates have suggested that 96% of marine species and 70% percent of land vertebrate species became extinct. It is also the only known mass extinction of insect with 56% of insect families and 83% of insect genera becoming extinct.
Little is known of the cause of the mass extinction but theories range from meteorite impacts, to volcanism, to sea level fluctuations.

When did the triassic period take place?
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.
Which eras on the geologic time scale is divided into both periods and epochs?
The Cenozoic era on the geologic time scale is divided into periods and epochs. This era includes periods such as the Paleogene and Neogene, which are further divided into epochs like the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene.
What hit atlantis a ttsunmai or an earthquake?
Atlantis was believed to have been hit by a powerful tsunami, as described by Plato in his dialogues. This catastrophic event led to the submergence of the island. It is theorized that the tsunami may have been caused by a major earthquake or other geological event.
Who proposed that all of the continents were once one large continent what was that one large continent called?
Alfred Wegener (a meteorologist - someone who studies the weather) was the man who saw that there were both fossils in brazil and africa. He also noticed that the coast fitted together, like a jigsaw. His theory was that there has been one big continent, which he named Pangaea. In 1912, there was no way of measuring the up to 10cm per year moving if the continents. Geologists believed that there has been a giant land-bridge between brazil and africa. In 1960, he was proved correct, because there were ways of measuring continental drift. TH
Is a rain check on a rainy day a pun?
Yes, a rain check on a rainy day is a pun, as it plays on the dual meaning of "rain check" as both a term for postponing an event due to rain and as a physical ticket that grants the holder the right to attend the event later.

What are the differences between the paleozoic mesozoic and Cenozoic eras?
The Paleozoic, the Mesozoic and the Cenozoic are the 3 Eras of the Phanerozoic Eon.The Paleozoic Era occurred between 542 and 251 million years ago. It lasted 291 million years. It was made up of 6 geological periods. The Cambrian Period(542 - 488Ma), the Ordovician(488 - 443Ma), the Silurian(433 - 416Ma), the Devonian(416 - 359Ma), the Carboniferous(359 - 299Ma) and the Permian(299 - 251Ma).The Mesozoic Era occurred between 251 and 65.5 million years ago. It lasted 185.5 million years. It was made up of 3 geological periods. The Triassic Period (251 - 199.6Ma), the Jurassic(199.6 - 145.5Ma) and the Cretaceous(145.5Ma).The Cenozoic Era occurred between 65.5 million years ago to now. It has lasted 65.5 million years to date. It has been made up of 3 geological periods to date. The Paleogene(65.5 - 23.03Ma), the Neogene(23.03 - 2.588Ma) and the current period the Quaternary Period (2.588Ma - Now)
What era was when the limestone and coal formed?
Limestone and coal primarily formed during the Paleozoic and Mesozoic eras. Limestone typically originates from marine environments and is abundant in the Paleozoic era, particularly in the Carboniferous period. Coal formation is also closely associated with the Carboniferous period when extensive swampy environments allowed for the accumulation of plant material. Thus, both limestone and coal are significant geological features from the Paleozoic era, especially during its later stages.
What times would be the longest a paleozonic b carboniferious period c Jurassic period d mesozoic era?
According to the newly released Geologic Time Scale (June 2012) these are the durations of the given options: a) Paleozoic: 258.8 million years b) Carboniferous: 60.0 million years c) Jurassic: 56.3 million years d) Mesozoic: 186.2 million years Its not surprising that the Carboniferous and Jurassic are the shorted as both are Periods one of the given Eras. So the Paleozoic is the longest of the four options.
When did the triassic period take place?
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.
Time periods of paleozoic and mesozoic subdivided into early middle and late?
The Paleozoic Era, spanning from about 541 to 252 million years ago, is divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian, with each period further characterized by distinct geological and biological developments. The Mesozoic Era, lasting from approximately 252 to 66 million years ago, is divided into three periods: Triassic, Jurassic, and Cretaceous, each marked by significant evolutionary advancements, including the rise of dinosaurs. Both eras represent critical phases in Earth's history, showcasing major changes in climate, life forms, and geological structures.

Do sharks lve in salt water?
The vast majority of sharks live in salt water.A small number of shark species do live in both salt and freshwater, like the Bull Shark (Carcharhinus leucas), for instance.And there are also five rare species of shark in the genus Glyphisthat live only in rivers.But many sharks lived in freshwater during the Paleozoic and the Mesozoic eras.
