Re: late night thoughts: misunderstand what?
AJ -- "If the predators won, the sauropod lineages would go extinct an
geological instant after hitting the ceiling; they couldn't "sputter",
since, under your scenario, any sub-size descendants would get eaten
even faster than those who merely failed to grow bigger."
A problem w/ the 'obligatory instant snuff out' premise outlined above is
this. If the taxa size variance begins to interact w/ a mass size limit,
the animals at the lower end of the variance, particularly those that live
in habitats that contain areas of refugia, are less affected than those at
the upper end of size variance.
it helps your case that you aren't saying what you consider to be refugia.
