The argument that there were still life after the impact of The Chicxulub is strong, but what proves that the method used to determine the existence of other animals after the impact is accurate.Lfamc (talk) 00:35, 11 April 2012 (UTC)[reply]

The ozone may have changed due to the impact of the asteroid, but it was not the reason for mass extinction. Studies on the impact site have shown that although the asteroid caused some change to the area, there were life forms around for many years after. These included some life forms that were very fragile. Cthom4751 (talk) 19:59, 6 April 2012 (UTC)[reply]
The mass extinction was not due to post-impact ozone conditions but from the after effects from the asteroid. The asteroid caused tsunamis and acid rain which first killed off all the vegetation.Acox967 (talk) 01:20, 26 September 2012 (UTC)[reply]
