|---|---|---|
| P. O. Antoine et al. 2011 | iny rodent (body mass estimated at approx. 40 g) characterized by brachydont and bunolo- phodont teeth. It differs from all other caviomorphs in having teeth with moderately low and sharp transverse crest(id)s, lower molars having generally incomplete metalophulid II, and pentalophodont upper molars with a well-developed metaloph that turns anteriorly (not pos- teriorly) and connects either to the mesolophule lingually or to the mesial extremity of the anterior arm of the hypocone—a primitive condition that is reminiscent of that found in stem Hystricognathi (e.g. Baluchimys, Protophiomys, Waslamys, Phiomys, Hodsahibia, Bugtimys and Ottomania). The lingual protoloph is either slightly
developed or lacking (i.e. taeniodont pattern). |
