How did the T. rex go extinct? rex went extinct during the K-T mass extinction, about 65 million years ago. This extinction killed the remaining dinosaurs (not just T. rex) and many other animal and plant groups. This extinction was probably caused by a catastrophic asteroid colliding with Earth.
What is the current increase in the background extinction rate? On the basis of these results, we concluded that typical rates of background extinction may be closer to 0.1 E/MSY. Thus, current extinction rates are 1,000 times higher than natural background rates of extinction and future rates are likely to be 10,000 times higher.
Why did the Ordovician-Silurian extinction happen? Around 443 million years ago, 85% of all species on Earth went extinct in the Ordovician-Silurian extinction. The extinction was a most likely a result of global cooling and reduced sea levels, which dramatically impacted the many marine species living in warm, shallow coastal waters.
