Figure 3. FSP-ITD 342, cranium. Stereophotographs of the ventral side the right auditory region. Abbreviations: BO, basioccipital; CF, cochlear fenestra; CT, crista tympanica; EC, ectotympanic with anterior and posterior crura; EO, exoccipital; ET, fragment of caudal entotympanic; FO, foramen ovale; GF, glenoid fossa; MP, mastoid process, PLEP, posterolateral extension of the petrosal; PN, petrosal notch separating the main part of the posterolateral extension from the promontorium; POAC, posterior opening of the alisphenoid canal; PP, petrosal promontorium; SQ, squamosal; TH, dorsal fragment of the tympanohyal. Solid circles indicate the area of attachment for brachio- and/or sternocephalicus; the solid triangle indicates the small depression posteromedially to the mastoid.
