morphology and delicate construction. Distortion is almost

that it's questionable whether there are ANY complete, undamaged and

Mmm... I don't see distortion as a major hindrance in recgonising toothmarks.
Surface cracking is more of a problem.
And why would you expect toothmarks from a kill anyway? Most (if not all) of
toothmarks I have observed (on other dinosaur taxa) are much more likely to be
from carcass processing.
I have mental picture of a big theropod biting into the neck of a sauropod,
piercing one of the air sacs, and the sauropod deflating like a giant balloon.
