This dying-off lasted for about 165,000 years and included both gradual and sudden environmental changes that greatly altered conditions on the Earth.
The Triassic–Jurassic (Tr-J) extinction event ( TJME ), often called the end-Triassic extinction, marks the boundary between the Triassic and Jurassic periods, 201.4 million years ago, [1] and is one of the top five major extinction events of the Phanerozoic eon, [2] profoundly affecting life on land and in the oceans.

Understanding the reasons and timelines of these events is important to understand the speed and scale of species extinctions today. When and why did these mass extinction events happen? What is a mass extinction?
In an extended period between 50,000 to 10,000 years ago, hundreds of the world’s largest mammals were wiped out. This is called the ‘Quaternary Megafauna Extinction’ event. Humans were the main driver of this, killing off species through overhunting and changes to their habitats. When: 359 million to 380 million years ago Why: While the term mass extinction may suggest instant global catastrophe, these events can take millions of years. The End-Devonian, for example, consisted of a series of pulses in climate change over 20 million-plus years that led to periodic and sudden drops in biodiversity, including the Hangenberg Crisis, which some researchers consider a ...Even after the extinction event itself abated, the extinction rate remained high for 5.4 million years; the ecological recovery period required another 6.9 million years.A species becomes extinct when the last existing member of that species dies.
