Agamidae View in CoL View at ENA ( Fig. 20A, B View Figure 20 )

The squamosal of Laudakia stellio is large, roughly straight in lateral view and slightly medially concave. The anterior process is large and has a rounded tip. The dorsal margin of this process has a large and concave articulation surface for the contact with jugal and postorbital ( Fig. 20A View Figure 20 ). The posterior portion consists of a strongly dorsoventrally expanded dorsal parietal process, which forms a subtriangular structure whose posterior margin, the contact surface with the supratemporal process of the parietal, is straight. A quadrate process is situated between the anterior and dorsal parietal processes. This third process is large and rounded, and contacts the quadrate with a flattened articulation surface visible in medial view. A straight ridge is visible on the medial surface ( Fig. 20B View Figure 20 ), which is otherwise smooth; the ridge runs from the base of the dorsal parietal process to the tip of the quadrate process. A small and dorsomedially directed triangular expansion is present on the ridge, near the parietal process. The lateral surface of the bone is smooth.
