No. I am arguing against the notion that ostriches falsify my idea
because they are big, non-stealthy egg layers. They survive (I argue)
because of grass (in fact, it makes them stealthy). I also argue that
dinos might not have gone out if there had been grass. As you say, none
of this relates to causation of dinosaur extinction because grass did not
exist back then.
