Flood Basalt
Edit : (thought I better add something to that)
The greatest mass extiniction in history was at the Permain boundary this is thought to have been caused by massive flood basalt extrustion, imagine most of a continent spewing lava at an amazing rate for 100's of years decades at a time.
In fact theres more evidence to support a flood basalt been the main reason behind the dino extininction at the K/T boundary than a metor however a combination of the two is most likely, the Iriduim layer found at the K/T boundary (indicating a metor impact) is found in the mddle of Flood Basalt extrustions in the Dakan Province of India, so it's likely the Dino's were been wiped out by the basalt, the metor kinda helped them along and anything left was wiped out by more flood basalt extrustions.
I could go in to more details but im tired , however if you want just ask.
