A, medial view of the posterior portion of the dentary; B, pterygoid fossa (pocket) in dorsal view; C, medial surface of the dentary showing no trace of the Meckelian groove; D, reconstruction of the lower jaw in medial view (the reconstructed teeth are shown in grey lines). Abbreviations: apc, anterior portion of the pterygoid fossa; arc, anterior ridge of the coronoid process; cmf, crest that defines the anterodorsal margin of the masseteric fossa; cp, coronoid process; ct, coronoid tubercle; md, mandibular condyle; mf, mandibular foramen; mrp, medial ridge of the pterygoid fossa; pc-b, pterygoid crest (broken); pf-d, pterygoid fossa in dorsal view; ppc, posterior portion of the pterygoid fossa.
