Does this help indicate the angle at which the front legs of triceratops were 
held?  If the leg is not straight and directly under the animal but splayed 
and at an angle, as I've seen it drawn, would all the weight of the head be 
put on a muscle or something else rather than straight onto the bone?  That 
seems like it could be painful as the animal got older.
