A new study of volcanic rocks has confirmed at least one mass extinction event was caused by massive "flood basalt events". In other words, a metric buttload of lava. I think then going on to claim that all mass extinctions are caused by volcanism seems a bit much, but I'm not a geologist, or paleontologist. But, hey, if it keeps the grant money flowing have at it.
