Does that matter? Try GSP.

Closer to the former. I'm sure it's all in the archives. As I wrote:

No, it's in the same paragraph; I refer to chewing. Herbivorous mammals 
can't take in food and chew at the same time; they can only take in food 
when they've finished chewing a mouthful. Elephants spend most of every day 
chewing... judging from their teeth, sauropods did not.
