"The combination of such characters ... will, it is presumed, be
deemed sufficient ground for establishing a distinct tribe, or
suborder, of Saurian reptiles, for which I would propose the name of
Dinosauria." (Owen, 1842)

If course, I'm not exactly sure what comprised _Sauria_ in Owen's
mind; it's been everything from a synonym of Lacertilia to a synonym
of crown clade _Reptilia_.

Why does everyone leave out poor old _Hylaeosaurus armatus_? (I guess
it *is* very, very likely redundant and not as well known as
_Iguanodon bernissartensis_, but still ... it *is* one of the original
three! And second listed, to boot....)
