About
Genasauria is a group of "bird hipped" (Ornithischian) dinosaurs that contains Thyreophora: the armoured battalion of stegosaurs and ankylosaurs, and Neornithischia: which includes the ceratopsians, pachycephalosaurs and ornithopods (collectively known as cerapodans), plus a gaggle of non-thyreophoran, non-neorhithischian, ornithischian outcasts.
Basically, Genasauria is Ornithischia without the basal ornithischians, all barring one of which are known as "heterodontosaurids". The odd one out is Pisanosaurus. No-one knows where that sucker belongs.

Etymology
Genasauria is derived from the Latin "gena" (cheek), and the Greek "sauros" (lizard) and "-ia" (a plural-forming suffix), named for all ornithischians with
muscular cheeks.
