Triassic-Jurassic extinction event - Wikipedi

The Triassic-Jurassic (Tr-J) extinction event, sometimes called the end-Triassic extinction, marks the boundary between the Triassic and Jurassic periods, and is one of the major extinction events of the Phanerozoic eon, profoundly affecting life on land and in the oceans. In the seas, a whole class and 23-34% of marine genera disappeared The Permian-Triassic extinction event, also known as the P-Tr extinction, the P-T extinction, 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 252 million years ago The Triassic-Jurassic extinction event was the fourth major global extinction of the Phanerozoic eon. The event occurred around 201 million years ago at the end of the Triassic Period (a period that lasted from 252-201 million years ago) Scientists don't yet know what caused the Triassic mass-extinction event — one of the largest extinction events in the history of our planet — 200 million years ago

  1. End-Triassic extinction, also called Triassic-Jurassic extinction, global extinction event occurring at the end of the Triassic Period (252 million to 201 million years ago) that resulted in the demise of some 76 percent of all marine and terrestrial species and about 20 percent of all taxonomic families
  2. The fourth major mass extinction event happened around 200 million years ago at the end of the Triassic Period of the Mesozoic Era to usher in the Jurassic Period. This mass extinction event was actually a combination of smaller mass extinction periods that happened over the final 18 million years or so of the Triassic Period
  3. It's uncertain how much of an effect the P/T Extinction had on diapsid reptiles, the family from which crocodiles, pterosaurs and dinosaurs evolved, but clearly a sufficient number of diapsids survived to spawn these three major reptile families millions of years later. The Permian-Triassic Extinction Was a Long, Drawn-Out Event
  4. The End-Triassic extinction event marks the boundary between the Triassic and Jurassic periods, 208 million years ago.

It is estimated that 50 percent of all species went extinct. Some paleontologists call the Triassic-Jurassic extinction the second greatest mass extinction of prehistory
  6. Like the better-known end-Permian extinction, the end-Triassic event may have been a result of global climate change. When did it happen? The extinction occurred near the end of the Triassic Period, about 201 million years ago

The Carnian event stood out in the epoch-level datasets for ammonoids and tetrapods, with an extinction peak in the early Carnian for the former and the late Carnian for the latter
  3. This event has been previously considered as the end-Triassic mass extinction horizon, however a second extinction is also seen at the top of the Langport Member after a phase of recovery marked by diversity increase. This younger crisis caused the loss of further bivalves, ostracods and the last of the conodonts. The two phases of marine extinctions coincide with marked turnovers amongst.

The Triassic-Jurassic boundary extinction event is one of the 'big five'mass extinctions of the Phanerozoic Eon, profoundly affecting life on land and in the oceans, explained Lawrence Tanner, a Professor of Geography and Geoscience at Bloomsburg University in Pennsylvania. Tanner presented his ideas on the various extinction theories Wednesday at the Earth System Processes meeting in. Late Triassic impact events have been considered a factor in biotic extinction events in the Late Triassic (e.g., end-Triassic extinction event), but this scenario remains controversial because of a lack of stratigraphic records of ejecta deposits. Here, we report evidence for an impact event (platinum group elements anomaly with nickel-rich magnetite and microspherules) from the middle Norian.
