preserve stability in the taxonomy of stegosaurian dinosaurs by replacing Stegosaurus
armatus Marsh, 1877, the unidentifiable type species of the ornithischian dinosaur
genus Stegosaurus Marsh, 1877, with the very well represented nominal species
Stegosaurus stenops Marsh, 1887, also from the Upper Jurassic Morrison Formation,
U.S.A. This genus is the basis for Stegosauria Marsh, 1877, STEGOSAUROIDEA Marsh,
1880, STEGOSAURIDAE Marsh, 1880 and STEGOSAURINAE Marsh, 1880. Maidment et al.
(2008) listed seven putative autapomorphic characters for Stegosaurus and five for
the species Stegosaurus armatus in its current usage. However, the holotype of S.
armatus, which consists of an articulated series of 18 incomplete vertebrae from the
proximal half of the tail and a very large but incomplete dermal plate, shows none of
these diagnostic characters and so S. armatus must be considered a nomen dubium.
However, the holotype of S. stenops Marsh, 1887 shares all 12 autapomorphies with
S. armatus in its current usage, being based on an almost complete skeleton (USNM
4934), most of it still in the rock preserving almost natural articulation, which would
make S. stenops by far the best available species to replace S. armatus as type species
of Stegosaurus Marsh, 1877.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Case</style></work-type><section><style face="normal" font="default" size="100%">127</style></section></record></records></xml>
