Notoparamys possessed a
midbrain partially exposed between the
cerebellum and
cerebrum but lacked visible rostral colliculi. The
incisor enamel of
Notoparamys costilloi was pauciserial. The mandibular fourth
premolar of
N. costilloi had a pattern of
Hunter-Schreger bands
known as an S-type schmelzmuster.
Occlusion in
N. costilloi was characterised by mesiolingual movement of the mandibular
molars across the maxillary ones in a similar fashion to the closely related
Paramys. == References ==
