Dino Demise by Angiosperms

["Becky Gould" <dagmardragonlady@hotmail.com>]

I ran across an interesting theory on how dinos bit the dust.  It had to do 
with the rise of Angiosperms, and the decline of Gymnosperms, the then major 
food supply for many Cretaceous dinosaurs.  Do any of you know where I can 
find more information on this topic?  What I've found so far has been 
interesting, how by late Cretaceous the dinosaurs had become extremely 
specialized, and by entering a new food group that the herbivores were not 
equipped to eat, started a decline in populations.

Any help would be greatly appreciated!
