Re: Theories on the extinction of dinosaurs



>>I predict it.  I am still in the hypothesis-forming stage.  You have moved
on to a position which, given current evidence, is untenable.  Simply, the
null hypothesis: Dinosaurs became extinct at different times in different
places, is not falsifiable using a single data point. <<

That woulnd't work.  For instance, if all the dinosaurs in Asia were driven
extinct by a meteor, then after the dust had cleared, the dinosaurs from other
places would recolonize the continent. And remember pterosaurs, which can fly
away from localized disasters.  Something would have to kill off _all_
dinosaurs _everywhere_ for any mass extinction to take place.  Perhaps minor
disatsers at various times through the K killed a few million dinosaurs here
and there, but there would have to be some _big_ disaster at the end that
finished them all off.
