The Triassic Period (252-201 million years ago) began after Earth’s worst-ever extinction event devastated life. The Permian-Triassic extinction eventPermian-Triassic extinction eventThe Permian–Triassic (P–T, P–Tr) extinction event, also known as the End-Permian Extinction and colloquially as the Great Dying, formed the boundary between the Permian and Triassic geologic periods, as well as between the Paleozoic and Mesozoic eras, approximately 251.9 million years ago.https://en.wikipedia.org › Permian–Triassic_extinction_eventPermian–Triassic extinction event – Wikipedia, also known as the Great Dying, took place roughly 252 million years ago and was one of the most significant events in the history of our planet.
Some of the biggest causes of mass extinctions include: Ocean/atmosphere chemistry Climate change Volcanic activity Meteor/asteroid impacts
The temperatures dropped significantly over a period of time, and so cold-blooded reptiles such as the dinosaurs were at a distinct disadvantage, while mammals and birds — who are warm-blooded — were able to survive. The changing climate also produced new ecological niches that they were able to adapt to and the large dinosaurs were not.
What caused the extinction? At the end of the Triassic, the supercontinent of Pangea, which combined all of the modern continents into a single landmass, began to break (rift) apart. As North America separated from Africa and the Atlantic Ocean began to form, volcanic activity on a massive scale introduced carbon dioxide into the atmosphere.
What went extinct in the Triassic extinction?
End-Triassic extinctions Many families of brachiopods, gastropods, bivalves, and marine reptiles also became extinct. On land a great part of the vertebrate fauna disappeared at the end of the Triassic, although the dinosaurs, pterosaurs, crocodiles, turtles, mammals, and fishes were little affected by the transition.
How many animals went extinct in the Triassic period?
Permian-Triassic extinction – 252 million years ago Over about 60,000 years, 96 percent of all marine species and about three of every four species on land died out.
What species died in the Triassic Jurassic extinction?
On land, all archosauromorphs other than crocodylomorphs, pterosaurs, and dinosaurs went extinct; some of the groups which died out were previously abundant, such as aetosaurs, phytosaurs, and rauisuchids.
How did the 90% of Earth’s species died in the Triassic period?
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.
What caused the extinction at the end of the Triassic period?
Huge and widespread volcanic eruptions triggered the end-Triassic extinction. Some 200 million years ago, an increase in atmospheric CO2 caused acidification of the oceans and global warming that killed off 76 percent of marine and terrestrial species on Earth.
What went extinct in the Triassic period?
All Triassic archosaurs, apart from dinosaurs, pterosaurs and crocodiles, went extinct. This opened up many of the environments that the archosaurs had occupied, paving the way for the surviving dinosaurs to take their place, while the small mammalian relatives still scurried around the forest floors.
What survived the end-Triassic?
All major groups of marine invertebrates survived the extinction, although most suffered losses. Brachiopods, shelled cephalopods, sponges and corals were particularly hard hit. On land, casualties included the phytosaurs, a group of crocodile-like animals.
What year did the Triassic Period End?
The Triassic–Jurassic (Tr-J) extinction event, sometimes called the end-Triassic extinction, marks the boundary between the Triassic and Jurassic periods, 201.3 million years ago, and is one of the major extinction events of the Phanerozoic eon, profoundly affecting life on land and in the oceans.
What caused the end of Jurassic period?

Was there an extinction at the end of the Jurassic period?
At the end of the period there was one of mass extinctions associated with the dinosaurs (Condie, 344). This dinosaur extinction was paralleled by a shift in dominate vegetation from the conifers and cycads of the Jurassic period to shorter, primitive flowering trees (346).
What are 3 major events that happened during the Jurassic period?
The start of the period is marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Late Piensbachian/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.
What was the major event in the Jurassic period?
During the Jurassic period, the supercontinent Pangaea split apart. The northern half, known as Laurentia, was splitting into landmasses that would eventually form North America and Eurasia, opening basins for the central Atlantic and the Gulf of Mexico.
