grass

Hi List--

>illustrate the fact that grass hadn't evolved,<

I thought I remembered reading someplace recently that there was evidence
that grass was more widespread in the late Cretaceous than was formerly
believed...? Can anyone confirm, or did I make this up? At the time I
remember thinking, "So maybe the arrays of teeth in T. horridus were an
adaptation for grass-eating..."
