RE: Ceratops (was RE Glishades ericksoni, ...)

The argument is that you can't prove it's the same type of organism of 
*Ceratops montanus*. Thus, if its from the same horizon, same locality, shows 
the same essential features, you meet a reasonable level of certainty it is the 
same type of animal, although it's hard to prove it; if you find a similar 
specimen from a different horizon, different locality, etc, that certainty 
decreases. One could just as easily have a different taxon. Because of this, 
referal of that specimen to a "nomen dubium" becomes assailable by the above 
argument, and I can be tempted to just separate the good material on its own 
after the fact; nothing keeps that specimen attached to the name by the 
holotype except for perhaps historical qualities.
