Re: Dromaeosaur tails and twisting



Well for one, long, thin zygopophyses might stiffen a tail but not make it stiff. Could the interpretation of the dromaeosaur tail as an extremely stiff, rod like structure be an over interpretation of dinosaur morphology driven by preconceptions about dinosaur paleobiology? Heaven forbid !!

Can anyone tell me if this tail has a twist in the distal end? Interesting that there is a s-curve though with all those long rods "stiffening" the tail. It seems as though the consensus is that the fossil is distorted.
Generally though, how much twist was there in dinosaur tails? For instance, could the tail of a T.rex twisted so that by the end of the tail the vertabrate have rotated 90 degrees? What modern lizards are good analogies for dinosaur tails. Are dino tails depicted as too stiff?
