Jaime... Please show in what post you delivered clear evidence that 
conclusively goes against the premaxilla of "Archaeopteryx", and the other 
theropods in question, having a single keratinous covering. This will answer 
both my question and the one posted by Mike. 

Now, to be perfectly clear, I do not want variations on the surface of the bone 
found under rhamphotheca. I want evidence that goes against there being a 
continuous covering on the premaxilla.
