I can add a possible example. The mount of _Triceratops prorsus_ (old name=
granted) at the Science Museum of Minnesota has a partially healed=
puncture wound just below the left eye. It was originally pronounced a=
predator wound, yet the injury occurs at such a wierd angle that this=
possibility becomes unlikely (also, I doubt if even T. Rex could bite hard=
enough to go completely through the skull bone). The new theory is that=
this wound occured during an interspecies battle. This one makes more=
sense anyway, since the wound appeared to come from the front of the animal=
Today there are many species with horned females. As an aside question, do=
any of these run into interspecies wounds (perhaps from another female)? I=
know that several species of Triceratops were lumped together for various=
reasons. If wounds of this kind are uncommon in females, then this could=
say that the SMM specimen is male. I know very little about ceratopian=
taxonomy, but could this help sort through what "species" goes where (might=
make sense, since this group was sexually dimorphic anyway)?
