This thread began as an attempt to explain why a _Triceratops_ skull shows
evidence of having been bitten on the *face* from the *front* by a
tyrannosaurid. My attempt to find the original post has been unsuccessful,
so I do not know whether this skull has tooth marks or embedded teeth in

It still seems like too much work for very little gain. There is no
evidence that tyrannosaurids had a den as such, and it would seem so much
easier for the young to travel to the site, for the parents to regurgitate
food for the chicks, or (as Ellen Sue Blakely suggested on 2/20/98) for
adults to bring only a portion of the carcass back to the family.

As I understand it, the robust, spike-like teeth of the upper jaw
overlapped the teeth of the mandible, giving it an overbite all around.
The teeth were continuously being pushed up and replaced by successive
teeth, giving the tooth line the characteristic jagged look. They did not
mesh together as our teeth do, and they were not blade-like as the teeth of
some of the smaller theropods. So it would not make a clean cut, but I
presume persevered by virtue of its robust teeth and powerfully muscled
neck and jaws. (Please correct me if I'm wrong about any of this).
