Lacertidae View in CoL View at ENA ( Figs 30 View Figure 30 , 31A–D View Figure 31 , 38D View Figure 38 )
In lacertids, the supraoccipital bears a cylindrical and stocky processus ascendens, which continues posteriorly on the dorsal surface of the bone with a low supraoccipital crest (sometimes sharper in adults of large species). The degree of ossification of the processus varies with growth and within species: in juveniles and small-sized species it is ossified only by its base, whereas in adults and larger species the ossification is more developed. Two lateral crests are present at the sides of the processus, running along the anterior margin of the bone and merging in the short marginal processes by the contact with the prootics. In most species, the anterolateral margins are convergent in dorsal view, giving a hexagonal shape to the bone ( Figs 30I View Figure 30 , 31D View Figure 31 , 38D View Figure 38 ), but in Ac. erythrurus they are roughly parallel ( Fig. 30D View Figure 30 ).
