Alternating in _Stegosaurus_, paired in more primitive stegosaurs.
Part of the failing of Czerkas' analysis was his lack of attention to
phylogeny. Other, more primitive stegosaurs (_Kentrosaurus_,
_Tuojiangosaurus_, etc.) have paired rows of scutes, so the expectation is
that _Stegosaurus_ had such, too.
