Just a small correction here... 

I have seen photographs of a recently-excavated specimen of _Torosaurus_
from ?Montana that has obvious epoccipitals, so despite the way this
ceratopian has been reconstructed and restored over the years, it's
apparent that it did indeed have them along the edge of the frill. As
for _Triceratops_, I would guess that most (if not all) of the specimens
with "smooth-margined frills" are casts of the mount at the AMNH; the
frill on that skull is *very* heavily reconstructed, and considering the
evidence from other _Triceratops_ skulls, is undoubtedly wrong.
