Although I haven't gotten through the dissertation by a long shot, it seems 
as if Dan finds only two distinguishable species of Allosaurus, namely, A. 
fragilis and A. jimmadseni. Even the Bakker-distinguishable species (A. 
atrox, A. maximus, A. amplexus, and so forth) and the Pickering species (A. 
whitei) may be accounted for by individual variation. Dunno what Dan would 
make of Wyomingraptor and Brontoraptor.
