The Triassic-Jurassic Extinction occurred around 201 million years ago and marks a significant event in Earth's history. This extinction event led to the disappearance of about 70-75% of all species, including many reptiles and amphibians. It paved the way for the rise of the dinosaurs, which would dominate the planet during the Jurassic Period. Several factors contributed to this extinction, including volcanic activity, climate change, and changes in sea levels. The massive Siberian Traps volcanic eruptions released large amounts of carbon dioxide, leading to global warming and ocean acidification. These environmental shifts drastically altered ecosystems, resulting in widespread species loss.
