The squamosal, pterygoid and maxilla are the first elements of the dermatocranium to begin ossification, which occurs in stage 16 (Figure 3B).
Sheil and Greenbaum (2005) suggest that the bones of the dermatocranium were grouped into elements of the palatum (pterygoid, vomer and palatine), maxillary arch (premaxilla, maxilla, jugal, quadratojugal and squamosal) and the roof of the cranium (prefrontal, postorbital, frontal and parietal).
The bones of the dermatocranium and the mandible are the first to begin the ossification process: squamosal, pterygoid, maxilla, dentary, coronoid, supra-angular and branchial horn I in stage 16, the frontal, jugal, postorbital, parietal, premaxilla and prefrontal in stage 17, and the palatine and quadratojugal in stage 19.
