Re: Big Dinosaur Prints Found

["T. Mike Keesey" <tmk@dinosauricon.com>]

A thought on the tail marks: suppose a theropod were to rear up a bit to
gain a better view. Further suppose it were to walk while doing so. Could
this lead to tail impressions on the ground? Is this biomechanically
feasible?

Now that I think about it, _Therizinosauria_ sort of evolved into this
posture, didn't they? Their long necks and more erect posture might be
adaptations for gaining a better view of the surroundings.
