No, and I'd like to. Can you give me a pointer to something reasonably
credible? I could use it!
I didn't know about the giraffes. Interesting!
Someone pointed out earlier that these strikes would be slow, and most
smaller predators would be amply graceful enough to dodge them. And of
course that's true. But *one* good hit, followed up by a trample, would
take the predator off the sauropod's "Dangers to me and my babies" list, and
out of its own gene pool. An attack that *will* finish you if it hits
would command some respect even if its odds were poor, and create
selection both among the prey and the predator.
Hmm. And if the neck-swinging sauropod is not itself the target of the
attack, but is hoping to blind-side a predator which is attacking another
member of the herd . . . ? Just might work. And if the predator is
actually clinging to its intended prey, and is thwacked by a big heavy
neck - instant two-dimensional carnivore, no trampling necessary.
Still, I concede that this is a Wild-Ass Guess about the utility of those
big necks. Easy to speculate, difficult to falsify, and I can't imagine
how it might be proved.
