Dinosaurweb has a short discussion on _Allosaurus_
that focuses mainly on the morphology of the lacrimal.
Can we assign subspecies in dino paleontology? It's
not like we can confidently tell if a new taxon
represents a sexually isolated species, so why not
name it _Allosaurus atrox jimmadseni_? Or just start
calling them _Allosaurus atrox_ morph 1, 2, 3,
4....you get the idea.
