Causes of Mass Extinctions: Testing Impact Models_Ward
This project was instituted to examine the relationship between impact and mass extinction. We know that one of the largest mass extinctions of the past 500 million years was caused by impact (the Cretaceous/Tertiary (K/T) event 65 million years ago (Alvarez et al, 1980)).
