Rothschild and Tanke (1997) reported on a pathologic skull of 
_Pachyrhinosaurus_ that preserves what seem to be, according to the authors, 
puncture wounds that fit a couple of horncores labelled "Monoclonius."  For 
more, see:

Rothschild, B. M., and D. Tanke.  1997.  Thunder in the Cretaceous: 
Inter-species conflict as evidence for ceratopsian migration?, in: D. L. 
Wolberg, D. Stump, and G. Rosenberg, editors, Dinofest International: 
Proceedings of a Symposium Held at Arizona State University.  Philadelphia: 
Academy of Natural Sciences, pp. 77-81.

Don't know of any other interspecific fighting reports, though I know Andy 
Farke might have something to say about INTRAspecific combat in 
ceratopsians...
