Actually, the neck of Diplo is remarkably flexible for its length. I
have a hunch that the diplodicids got longer for the same reason that
camarasaurids got bigger, they both get a better reach far more
efficiently then they would by rearing.

Yeah, if an allosaur were to play spotter for a diplodicus, it would
*become* the spot!
