Fig. 7. Reconstructions of palatal structures of Coryphomys buehleri based on reciprocal mirroring of the left and right palatal fragments of specimen AMF 68751. The specimen is shown in (A) ventral and (B) dorsal views. The ventral view dramatically illustrates the extremely large size of the molars relative to the osseous structures, the very short and narrow nature of the paired incisive foramina (ifn) and the broad antemolar palatal fossa (amf). The dorsal view illustrates the marked narrowing of the nasopharygeal sulcus (nps) between the molar rows and the elaborate nature of the maxillary sinus complex (msc). Scale bar represents 10 mm. White line is posterior margin of preserved right maxilla.
