Unfortunately this Discovery article (which also rehashes several arguments 
that were refuted long ago) doesn't mention if Arens made any attempt to get 
things like the Signor-Lipps effect and local variations of the environment 
to find the gradual decline in the number of angiosperm and mollusk species 
(interestingly 90 % for both). I don't assume Arens is stupid, so I'm sure 
he did something, but how much, and what?

Strange that the article mentions a _trans_gression where everyone else 
mentions a _re_gression.
