        Yep!  El Correcto! :-)  It was.  And it was a Dr. Mook, who is a
cancer specialist.  I have or HAD a copy
        of that paper.  The photos surely LOOKED like lesions, but...  I may
have also read that in another
        reference.  Anyway, I'm still searching through my books; MANY of
which are still packed after a
        recent move.  I'll update if I locate the 2nd reference.

        It makes sense (ALWAYS risky in science) that ceratopsians would
suffer injuries, especially to
        horns, frills, etc.  This occurs quite frequently in elephants
(tusks) & rhinos (horns).  There are 3 "white" rhinos in our city zoo, & the
large male has a truncated horn that appears to have broken off ~ 75% of the
way up & healed.
