Sexual Dimorphism in Stegosaurs

[Pachyrhinosaurus]

I found this interesting:

Its strange that they're calling hesperosaurus a species of stegosaurus.

His response makes a lot of interesting points.  It looks like he believes Hesperosaurus is a species of Stegosaurus.  This made me look into it, and it seems there's disagreement on whether Hesperosaurus is or isn't a species of Stegosaurus.

I still think its potentially erroneous to assume these differences represent gender dimorphism. It seems like that's the "the-go" assumption for slight differences in fossils.
