Re: Gastric stones of dinosaurs were not for milling food !
Yeah it matters... Build a set of model jaws, see how much leaf mass you can
strip off of various types of branches in a day. I haven't seen where anyone
has done that and concluded it was a slamdunk to gather several hundred kilos
of leaves every day, but I am sure I missed something. You got a ref, I would
really appreciate it.

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.
