Agamidae View in CoL View at ENA ( Figs 2A–D View Figure 2 , 3G View Figure 3 )
Laudakia stellio has an unpaired, T-shaped and flat frontal, with a posterior end that is roughly twice as large as the anterior one. The constriction at midlength is weakly developed in adults, but strong in juveniles. The lateral margins are strongly concave and the posterior one can be straight, with only a slightly wavy shape in the middle, or convex with a posterior expansion. In HUJ.OST-Z-423, this expansion lodges the subcircular parietal foramen ( Fig. 2C, D View Figure 2 ). Smith et al. (2016; see their supplementary information) reported that this expansion can be already well developed in young individuals. The anterior margin has two lateral processes and a medial process. Each lateral process is separated from the medial one by a moderately deep concavity. All processes are pointed, moderately large and equally long. Posterolateral processes are long and slightly dorsoventrally expanded ( Fig. 3G View Figure 3 ). The dorsal surface is smooth and distinctly sunken along midline. Articulation surfaces with the nasals are large, deep and U-shaped in dorsal view ( Fig. 2A, C View Figure 2 ). A well-developed ridge separates them medially and lower ridges separate each one from the corresponding articulation surface with the maxilla and the prefrontal. No articulation surface with the postfrontal is visible ( Fig. 3G View Figure 3 ). Cristae cranii are not developed and are represented only by weak ventral swellings along the lateral margins ( Figs 2B, D View Figure 2 , 3G View Figure 3 ). The swellings are slightly more developed in the anterior-half of the bone, but actual anterior processes are not present. The anterior-half of the ventral surface is strongly sunken. Maximum length of the frontal varies from 5 mm to 10 mm.
