Ok, we don't really have that much more to say about this now anyway.
I'm sorry I came across with an "authoritarian tone". Actually, I was
discovering some data that I hadn't seen (and should have said so). I have
both Hughes' 1976 book and the 1994 one, but hadn't really explored the
latter yet.
In it (I see now) he dropped his earlier complaint of Cretaceous paucity.
Thanks again for your input, even the bluntness. I need to be more humble.
