In summary, it is not only essential for determining the anterior border to the progression furrow but also for the morphogenesis of major parts of the dorsal and ventral ( gena ) head.
Its posterior margin runs at right angles to the longitudinal axis, before swinging inwards to form distinct genal angles and a genal epimeron on the left-hand side.
The genal spine of the very smallest specimens is about as long as the remainder of the cheek, and remains distinct until late in meraspid ontogeny.
Genal regions are angular but are not developed into genal spines.
Outside this angle the cephalic margin curves backward and outward, forming a notch beneath which the antenna may have emerged, then curves backward into the genal spine.
