Although Horner didn't state it as such, I noted at the talk that several of
the features (especially concerning development of the
nasal horn and orientation of the postorbital horns) that distinguished
subadult from adult _Triceratops_ are ALSO traits used to
distinguish _Diceratops_ from _Triceratops_. So regardless of whether
_Diceratops_ is its own genus (or species of _Triceratops_) or
not, the type was likely not fully grown.

Indeed, I believe that Horner is among the "_Nano._ as baby rex" crowd (as am
I, for the time being).
