The cartilaginous scapulocoracoids are small and joined across the ventral midline of their clavicular processes. Of particular interest is the fact that the scapulocoracoid articulates with and is partly supported by a massive rib attached to the occipital segment of the head. Articulation is through a cartilaginous process of that rib. Whereas this cranio] bone exoccipital ligament uprocleithrum cleithrum pectoral fin -cranial rib scapulocoracoid cartilage Figure 6-59.
