Re: Sauropod Tails (The End)

Has any thought been given to the idea that the supersonic cracks of just
one saurpod, standing alone  (so it doesn't hurt its herdmates), might be
used as a warning signal.  Such a warning would certainly be audible,
even if most of the herd was  busy browsing and therefore not paying much
attention to potential predators.
Is this a testable hypothesis?
