ReferenceDiagnosis
M. Watabe et al. 2011A small pachycephalosaurid that differs from Prenocephale brevis and all other pachycephalosaurids in having the following combination of characters: deep supratemporal fossae; broad (craniocaudally) prefrontal sutural surfaces with the nasal prefrontal and anterior supraorbitals surfaces lying in a single plane; short parietal (parietal length to the frontoparietal length is 2.44); posterior medial extension of the parietal sharply downturned; posterior medial extension of the parietal wide relative to the maximum width of the frontoparietal; and supratemporal fenestrae absent.
