basal bone

Cases with insufficient growth to overcome the tooth material - basal bone discrepancy.

The dermal skeleton is just surface dentin and basal bone, which is sometimes overlaid by enameloid.

The pterygiophore (the basal bone supporting the illicium) of Lasiognathus is unusually long amongst anglerfish, measuring some 85% of the standard length.

Teeth were first seen in chondrichthyans and were made from all three components of the dermal skeleton, namely dentin, basal bone and enameloid.
