extinction & impact link page

[Jeffrey Willson <jwillson@harper.cc.il.us>]

An interesting page with many links on the K-T impact and other K-T
extinction theories is:     <http://pibweb.it.nwu.edu/pib/catastro.htm>

(Look for the word "Cretaceous" to jump to the relevant section)

This page is primarily about the possibility of asteroid impacts in early
historic and recent pre-historic times. I have not tried to access all the
links.
