This chapter presents a cladistic analysis of the phylogenetic relationships of basal Ornisthischia. Ornithischia is a stem-based taxon defined as all dinosaurs closer to Iguanodon than to Cetiosaurus. Basal ornithischians includes Lesothosaurus, Pisanosaurus, and Technosaurus, Basal ornithischians are small (1-2 m long), obligate bipeds that exhibit anatomical features normally linked with a herbivourous diet. Because fossil remains of basal ornithicians are rare, little can be said about their paleoecology. Local environments from which these animals derive represent chiefly semiarid habitats. As herbivores, they may have been active foragers of ground cover and shrubby vegetation.
