Indubitably.  It has been several years since I, at least, l;last suggested
otherwise.

Indeed, I would say it is *the* question wrt the K-T extinction.

There are really only two widely held competing hypotheses: the pure impact
model, and the multi-factorial model.  In the latter the impact is, of
course, one of the many factors contributing to the extinction.


Note, recent evidence of a major impact in the Late Carnian is suggestive
that a large impact per se is insufficient to cause a major extinction, as
it does NOT correlate well even with a relatively minor mass extinction.
