Chamaeleonidae View in CoL View at ENA ( Fig. 21C, D View Figure 21 )

No conch and no medial lamina are present in the quadrate of Chamaeleo chamaeleon , which consists only of a straight pillar. Therefore, the bone turns up to be roughly rod-like in shape, with an anteroposteriorly compressed appearance and a dorsal end that is larger than the ventral one. The cephalic condyle is subdivided into three portions: an oval-shaped (in dorsal view) and dorsally flat articular surface contacting the quadrate process of the squamosal, a small lateral head embracing laterally the same process, and a larger and thicker medial head contacting the paroccipital process of the otooccipital. The mandibular condyle is flattened, because its concavity is poorly developed. The anterior surface of the bone is flat or concave ( Fig. 21C View Figure 21 ), whereas the posterior one is slightly convex ( Fig. 21D View Figure 21 ). A foramen can be present on the posterior surface, on the base of the medial head of the cephalic condyle. The maximum length of the bone ranges from 6.9 mm to 10 mm.
