The skull in the figure on Discovery is a cast reconstruction. The 
original is pretty flattened (although there is good element 
representation). The appearance of incompletely fused epoccipitals is 
just a product of the cast reconstruction in the figure, and my 
impression from seeing the original material at the Ceratopsian 
Symposium is that it probably was a full adult. And a big skull!
