Unfortunately, there is none of the axillary evidence for a major impact at
the P-Tr boundary.  There is no widespread tektites, or shocked quartz.
There is no non-climatic alteration in chemical or isotopic content.

Also, what evidence does he have of the dating?  This is critical.

[The URL you give does not, in any way, present any evidence.  It merely
present the author's model of the extinctions as fact, with no supporting
discussion - something that is this controversial should at least be
presented as undecided, not as fact].
