Diagnosis
ReferenceDiagnosis
P. M. Barrett et al. 2005(characters from the original diagnosis marked with ‘*’). A small ornithischian dinosaur that can be distinguished from other basal ornithischians by the presence of several cranial autapomorphies: presence of a palpebral/ supraorbital bar that traverses the width of the orbit* (acquired convergently in Dryosaurus); premaxillary teeth opposing three teeth in the rostral part of the dentary*; rostralmost dentary teeth conical, resembling premaxillary teeth; presence of a series of low, rostrolaterally directed ridges on the orbital portion of the frontal; and presence of an excavation or embayment on the ascending process of the maxilla, immediately rostral to the antorbital fossa.
