Congenital anomalies included ankylosis between the right femur and its ischium in an individual in early infancy.
The other ischium was never illustrated and its whereabouts is unknown.
The curvature of the ischium and absence of an obturator foramen were not characteristics seen in other pachycephalosaurs.
In the pelvis, the ilium, ischium and pubis are fused.
It is made up of the ilium, the ischium, and the pubis.
The fossil remains included vertebrae, limb bones, scapula, hip bones (pubis, ilium, and ischium) and several ribs.
In front of the right ischium muscle fibres are present running from the ischial foot in the direction of the femur.
Below, it is continuous with the pelvic surfaces of the ischium and pubis, only a faint line indicating the place of union.
