Chamaeleonidae View in CoL View at ENA ( Fig. 38B, C View Figure 38 )

The supraoccipital is the largest bone of the braincase of Chamaeleo chamaeleon . In the middle of the dorsal surface of the bone, there is the very well-developed processus ascendens, developed in anterodorsal direction and strongly expanded dorsally to form a tall median crest ( Fig. 38B View Figure 38 ). The dorsal expansion of the processus contacts the parietal crest of the parietal. On both sides of the processus ascendens, two well-developed and anteriorly projecting cylindrical processes are present. The common crus is absent and the semicircular canals enter directly the cavum capsularis.
