New Supernova paper

[Doug Erwin <MNHPB028@xxxxxxxxxxx>]

Dear Norm,
  What did I ever do to you Norm?  Don't answer that.
  I suppose the Schram is Fred Schram?
Iguess I will have to go dig out a copy of the paper,but I can't imagine
what unusual isotopes of common elements they mean.  More to the point
however, I cosmic ray bombardment should leave relatively obvious
differences in extinction-survival patterns.  For starters, shallow-water
forms should be more heavily affected than deeper-water marine taxa, and
terrestrial stuff more than marine (cosmic rays don't penetrate very far
into water).  It is true that fusulinids were evidently in shallower water
than other forams and suffered heavier extinction, but if you look at other
groups there is no evidence that I can think of in favor of this pattern,
and (positive evidence coming up here folks, just to make Stormin' Norman
happy) considerable evidence against.  I don't suppose the guys who wrote
this bothered to attempt to test it at all against the fossil record,
did they norm?
