Re: Suspicious impact craters and iridium layers?

[Dora Smith <villandra@austin.rr.com>]

I have an idea about this impact crater debate.   I don't know if it's the
first time I've said so, or not.

Good evidence supports both the impact theory, and the Indian traps theory,
of the end Cretaceous extinction.

Can it be that more than one factor contributed to such a catastrophic
extinction, and that the extinction itself took longer than one factor would
explain?     It really isn't inconsistent to think of it that way.

Also, the end Permian extinction has been shown to have taken an extremely
long time to come about.   The environmental impacts of the catastrophes
that caused it occurred in stages over a long period of time.    It wasn't
just a meteor fell or whatever and the following year, everything was
extinct.
