While some scientists think a large asteroid killed off the dinosaurs (also known as the impact theory), many paleontologists feel that climate change due to a drop in sea level might have been responsible.
Ancient volcanic eruptions didn't play a role in the mass extinction that killed off the dinosaurs, a new study says, putting the blame solely. Throughout Earth's history there have been many ice ages.
The last one ended ab years ago. A very severe ice age could have changed temperatures and frozen a lot of Earth's water.
