Okay...point taken, its not absolutely necessary, but it certainly helps.

Well, keeping in line with the original statement/query by Cindy Johnson,
I was assuming "fruit" to mean large fleshy produce from angiosperms,
something big enough to keep a pachycephalosaur fed without requiring
too many dents in the braincase.
Which isn't to say that I agree with her supposition. My original
thoughts were that it was a bit early for modern fruits and it appears
that this has been borne out at least in part. It sounds like we're
still talking about diets consisting largely of foliage and tough
pod-like structures along with small berries or proto-berries
at this point. A bit early for Pachys to be able to sustain themselves
by whacking apple trees or the like.
