Researchers debate theories about the Triassic-Jurassic extinction event's origins, which include climate change, asteroid impacts, and volcanic eruptions.
The Triassic and Jurassic mass extinctions: what happened?The end-Triassic extinction was brought about by massive and extensive volcanic eruptions. Around 200 million years ago, an increase in atmospheric CO2 led to the oceans becoming more acidic and the Earth being warmer, which contributed to the extinction of 76% of marine and terrestrial species.
Which are the top 4 reasons for mass extinctions?Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like a supervolcano erupting or an asteroid impacting Earth have all been responsible for previous mass extinctions. We are aware of them because the fossil record demonstrates how life has altered over time.
