Re: Triceratops questions

I remember that, when I was young, _Triceratops
calicornis_ was, AFAIR, the most famous species of _T._.
I know that since that time _T. horridus_ has been
assigned to that peculiar species. I find calicornis
sounds better than horridus (for a child's mind). My
questions are: since when horridus has taken over
calicornis, and for how long this last one has been used
(before horridus became the officical species name, by
precedence I presume)?
_Triceratops horridus_ (originally _Ceratops horridus_) is the type species
for _Triceratops_, so it will always have priority over _Triceratops
calicornis_ in the event that the two are synonymous (as appears to be the
case). Both species were named by Marsh: _horridus_ in 1889, _calicornis_
In her 1996 study of the genus _Triceratops_, Cathy Forster recognized only
two valid species: _T. horridus_ and _T. prorsus_. She also regarded
_Diceratops hatcheri_ as a valid genus and species.
