Critique
No definition has been proposed. Lambe (1918:35) erected the family without a type genus and in redundancy; it included only the genus Stegoceras. Thus Psalisauridae is not a valid taxon, as noted by Gilmore (1924:9) and Chure and McIntosh (1989:78). Glut (1997) considered this taxon equivalent to Pachycephalosauridae.
