Re: dino cycad PDF

Belated thanks to everyone who sent me the pdf! It is very interesting and 
quite convincing.

It is also testable: it predicts that there were more cycads in the Late 
Cretaceous in the sauropod-dominated southern continents than in the 
ornithopod-dominated northern continents. Unfortunately I know very little 
about the paleobotanic record.

(For those who have forgotten, the article was announced over a month ago, 
and explains the toxicity of cycad fronds and seeds, the edible and sugary 
seed coats, the size, color and accessibility of the seeds, the wide 
distribution of cycads during the Mesozoic, and their island-like relictual 
distribution plus high diversity throughout the Cenozoic by suggesting that 
large herbivorous dinosaurs that didn't chew much were the main seed 
dispersers.)
