Dermethmoid: (Figs.3 & 4)
The dermethmoid is a median dorsal bone situated at the anterior end of the skull. It
has two small frontal processes articulating with the premaxilla in front. Posteriorly,
it is drawn out into two stout processes, which articulates with the anterior ends of
the frontoparietals. The posterior ventral part of the dermethmoid is excavated and
into this excavation fits the anterior extremity of the parasphenoid. The dermethmoid
contacts the premaxilla anteriorly; the frontoparietals posteriorly; the parasphenoid
