W. W. Korth and C. Branciforte 2007 | Skull features distinct from other florentiamyines (from Wahlert 1984): no flange on frontals above orbits; posterior palatine, dorsal palatine, optic and sphenopalatine foramina more anteriorly placed; incisive foramen smaller (length approximately 12% total length of upper diastema). Dental features: cheek teeth submesodont, similar in crown height to Proheteromys but cusps more bunodont; premolars sim- ple; P4 with simple protoloph (consisting of circular protocone and occasional minute cuspules); P4 consists of four main, subequal cusps (no protoconid) with occa- sional minute accessory cuspules; transverse valley of molars relatively shallow, lophs uniting centrally after only moderate wear; lingual cingulum on upper molars continuous (not interrupted by transverse valley). |
