Then that is not a "correction". You are actually agreeing with my
interpretation of your views. ;-)

The timing of these published opinions matters little to me (I also don't
care who first published them). It's more important that they are

"Milton Krogman, the foremost expert on the human skeleton in foresic
science". (Sorry, I couldn't resist! This is an inside joke from Usenet
that only a mercifully few list members will understand. But I digress).
To *describe* a section of strata doesn't not necessarily mean that the
describer *understands* what he is describing! ;-) Keep in mind that,
prior to the discovery of the K-T iridium layer, stratigraphers didn't
have ANY experience working with world-wide chron-layers. This means
that, prior to Alvarez et al.'s first paper, Dr. Vail had no experience
with the subject. This is not an indictment of Vail, it's just a
I should point out that A. S. Romer, father of modern vertebrate
paleontology, has had more than a few of his own ideas disproven over the
years. Possessing name recognition doesn't mean that one is not
vulnerable to having one's ideas falsified.

I think I will let my participation in this thread die a merciful death.
My view of the K-T debate is that it shouldn't be about individual
personalities, nor should it rely on name-dropping for support. Instead,
it should be about the science.
