During the "Great Dying," a mass extinction event that occurred approximately 251.9 million years ago, a significant portion of life on Earth perished. Specifically, up to 96% of all marine species and around 70% of terrestrial species, including plants and insects, were lost.
Here's a more detailed breakdown:
- Marine Life: The vast majority of species living in the oceans disappeared.
- Terrestrial Life: A large percentage of land-based species, including plants and insects, also went extinct.
The 'Great Dying' represents the most severe mass extinction event in Earth's history, profoundly reshaping the planet's biodiversity.
