Re: percentage of_T. horridus_skulls showing healed scars resulting from intraspecific combat?
It's fairly small, I suspect. I know of a total of nine _Triceratops_
specimens with pathologies of some sort or another. This includes horn,
frill, scapula and facial pathologies. However, not necessarily all of these
resulted from combat. *Very speculatively*, I would say that perhaps only
half of these injuries resulted from damage inflicted by other
Some of the more "spectacular" specimens:
SSM P62/1/1 has a pathology on its jugal. This is described in:
Erickson, B. R. 1966. Mounted skeleton of _Triceratops prorsus_ in the
Science Museum. Scientific Publications of the Science Museum 1:1-16.
USNM 4708 possibly has a broken and rounded brow horn. See:
Gilmore, C. W. 1919. A new restoration of _Triceratops_, with notes on the
osteology of the genus. U.S. National Museum Proceedings 55:97-112.
For a summary of ceratopsian pathologies and hypotheses on their origin, I
refer you to:
Rothschild, B. M. and D. Tanke 1998. Thunder in the Cretaceous: Interspecies
conflict as evidence for ceratopsian migration? In: Dinofest International
Proceedings, Wolberg, D. L., E. Stump and G. D. Rosenberg, eds.
Philadelphia: Academy of Natural Sciences, pp. 77-81.
I hope that gives you a place to start. . .
