Good question!  And is there anyone out there who knows much about 
rhinoceros behavior - what is the primary employment of the rhino horn? 
The only pachy skull I ever saw seemed to have a heavily-vascularized 
horn lump, perhaps suggesting a since-lost overlay of horn of some 
significance.  
Thanks.
