If compared with that of gekkotans (Fig. 48A; see also: Villa et al., 2018a), the coronoid is only moderately concave in the medial direction in lacertids (Fig. 48B). The coronoid process is robust and has a rounded dorsal end that is slightly posteriorly directed in Ac. erythrurus , Al. fitzingeri , Al. marchi , Ophisops elegans and in juveniles of other species ( Fig. 47E, F View Figure 47 ). The anteromedial process is ventrally expanded and the pointed anterior end is represented by a small projection that is more developed in adults of Al. marchi , I. cyreni , I. monticola , Po. bocagei , Po. carbonelli , Po. hispanicus , Po. muralis and Z. vivipara than in juveniles and in other species. The posterior process is short and rounded and, therefore, the posterior portion of the coronoid has the shape of a lappet with a wavy posterior margin. A shallow concavity on this latter margin represents the anterior margin of the adductor fossa. Sometimes, the posterior process is slightly more developed and, therefore, the concavity is moderately deeper. The posteromedial process is moderately large, roughly rounded and distinctly ventrally directed. A moderately to well-developed coronoid ridge runs on the medial surface of the latter process, starting from the coronoid process. A second moderately developed ridge connects the posterior surface of the coronoid process with the dorsal surface of the posterior one.
