percentage of_T. horridus_skulls showing healed scars resulting from intraspecific combat?

[Shawn H <ih8wasps@yahoo.com>]

hello all,

i was wondering if any of you were familiar with the
statistics on the percentage of_Triceratops horridus_
skulls having healed scars that resulted from damage
inflicted by the horns of members of the same species.

any information you could bring to my attention on
this matter will be much appreciated.

thanks in advance,
Shawn Haugrud
