Extinction 65 millions years ago
- Thread starter John Justice
- Start date
In summary, extinction 65 million years ago refers to the mass extinction event that occurred at the end of the Cretaceous period, resulting in the disappearance of over 75% of all plant and animal species on Earth. This event is believed to have been caused by a combination of factors, including a large asteroid impact, volcanic eruptions, and climate change. It marked the end of the reign of dinosaurs and paved the way for the rise of mammals and other modern species. This event has had a lasting impact on the Earth's ecosystems and continues to be studied by scientists to understand its causes and effects.
