No positive evidence for it, no. (At least as adults)

Those who advocate(d) this idea suggested a keratinous horn rising from the
mass, rather than one with a horn core. So more rhino than bovine.

Not with me it ain't. And Witmer clearly has evidence that at least a
rhino-type attachment was not present. I can't speak for others.

Again, though, this was due to the way the program was organized: the models
were done and the fights decided and being animated prior to the interviews
with the consultants.

Yes, it was indeed the Week of Pachyrhinosaurus!
