   I am curious as to the amount of muscle-and-other-tissue found
between the rear-wards projection of the pelvis (on therapods) and the
underside of the actual tail after the cloaca.  I've seen artists
reconstruct this area both as filled in to create a fairly smooth
silhouette, and having it showing a very severe "dishing".
   Which is more accurate?  How would this difference in mass in a
reconstruction change the projected weight of an animal?  On a T
rex-sized animal, this could be several hundred pounds, right?
