  We explain that Stegosaurus exhibited exterior chirality and observe that the
largest plate in particular of USNM 4394, USNM 4714, DMNS 2818 and NHMUK R36730
appears to have tilted to the right rather than to the left in each case.
Several instances in which Stegosaurus specimens have been confused with their
distinct, hypothetical mirror-image forms are highlighted. We believe our
findings to be consistent with the hypothesis that Stegosaurus's plates acted
primarily as display structures. A collection of more than one Stegosaurus
might be referred to henceforth as a 'handful' of Stegosaurus.
