Again, how can this work for animals like _Triceratops_, who don't have any
fenestrae?  The frill is solid enough to make it impossible for a muscle to get
to the frill by going *through* the skull.  It seems to me that the only way for
the muscle to go is outside the skull.  Whether this is unique to Trike, or
common for the group, is open to debate.
