Re: sauropod rearing

point well taken re lack of pollex for titanosaurs :)

Regardless, for the male to climb up and drape itself over the female (which might be kneeling or lying down, per Richard Travsky) seems easier than maintaining a bipedal/tripodal stance. Anyway, can you briefly enumerate a bit about "the most adaptations for rearing of all sauropods"?

Thanks,
Kent

Oh, and rearing up for mating is just not the same problem (as we
all know).  Sauropods could rear up to mate as if partaking in a
bit of mountain climbing, engaging the pollex claw as a crampon,

That part was seemingly not possible for the most derived titanosaurs, which apparently lacked any trace of fingers... which, however, seem to show the most adaptations for rearing of all sauropods.
