I'm perusing Galton (1973) ("The cheeks of ornithischian dinosaurs") right now. If there's any more recent papers that address the cheek issue, let me know. Obviously these animals spent a lot of time masticating food - they have what amounts to a secondary
palate - but I guess the question is whether they *needed* cheeks in order to efficiently process a bolus. Because we don't know (as Dr. Holtz just stated, tersely) that they were there, I assume we must ask if they *should*, or *could* have been present.
Also...Is there more technical term to refer to these structures than "cheeks"?

We still don't know.
That's (unfortunately) the answer.
