Prior to the extinction of all dinosaurs 65.5 million years ago, a massive series of volcanic eruptions in India had been releasing carbon dioxide into the atmosphere for 10 million years. This caused significant climate change that greatly reduced the number of dinosaur species. However, that was not enough to bring about the extinction of all dinosaurs. 65.5 million years ago, though, a 6 mile wide asteroid slammed into what is now the Yucatan Peninsula, filling the atmosphere with so much ash that sunlight was blocked for months, maybe years. As a result, plants died and the entire food chains that dinosaurs depended on collapsed, causing the extinction of all dinosaurs, except the birds.
