Doug -

        Yes, it's the specimen being prepped by Donna.  I don't know what 
Greg was doing with the picture; I don't have it hand, though I've seen 
it.  The plates are offset from the centerline, as one would expect with 
a double row!  When he mentioned other "_Stegosaurus_", he didn't mean 
that genus; I think you may have inadvertently misread it!  I think he 
meant that other "stegosaurs," like the African and Chinese genera, seem 
to retain double rows of plates; the American genus fits nicely with that 
now!  It's just that the plates on the American genus are so much larger 
than the other steogsaurs!
