All the 300 km hole proves is that a large meteorite impact occurred. It
in no way proves the Doomsday scenarios built around said impact. If the
fossil biological evidence is inconsistent with a particular scenario, then
that scenario is WRONG, even given the impact.
The Doomsday scenario in the newspaper article originally cited is WAY
beyond anything supported by the actual fossil evidence.

Spectacular does not necessarily mean utterly devastating.
The statement in the newspaper article: "Had the dinosaurs still been alive
- and that is open to debate - then this impact would have killed them in
most places on the Earth."
is most certainly excessive. The most that can be said with any certainty
is: this impact would have killed many of them in many places on Earth.

You are here discussing a *different* scenario than the one discussed in
the silly newspaper article.
