I am glad to forward this message by Andrew Ross, concerning insects at the
K/T boundary. He sent it offline and gave his permission to post the
information on Paleonet.

>I have built up a database of all insect families found in the fossil

>the K/T boundary.  The radiation of the angiosperms during the Lower
>Cretaceous had a much more dramatic effect on them.
