Description
Global phylogeny of Ornithischia has undergone a major revision in how we view relationships within it due to the addition of new taxa and characters, with some of the traditional clades drastically repositioned or limited in taxonomic scope. Recent analyses have attempted to widen the taxonomic and geographic scope, but questions regarding the placement of putative basal taxa in larger clades such as Genasauria and Neornithischia still remain. Using a global phylogenetic analysis of basal ornithischians, Dr. Marc Spencer estimated the ancestral morphology of Ornithischia and several major clades within it. The estimated ancestral ornithischian (depicted here) was bipedal with a generalized skull and relatively long forelimbs more akin to basal saurischians from the middle Jurassic of southern Gondwana.

Looked more like a furry armorless version of Lesothosaurus.
