Long necks in large sauropods probably served to
enhance the _kilos of forage per step_ ratio.
Is holding a neck horizontally and swinging it around really cheaper than
taking a few steps? GSP says no...
The question of how large sauropods obtained enough
forage was quite controversial at one time, and never
satisfactorily resolved to my knowledge.
Obviously I haven't done any math, but can't they have eaten conifer needles
like other people eat grass, I mean, er...?
Forests probably reached farther into dry regions in the Mesozoic than
today, for two reasons: the absence of grass, and the extreme adaptations to
drought of some Cheirolepidiaceae.
