Diagnosis
ReferenceDiagnosis
R. Sostillo et al. 2014Dp4 trilophodont with small mesolophid (or metalophulid II?) spur. Lower molars with mesoflexid more ephemeral than that of R. plesiodon. Mesoflexid trans- formed into mesofossettid in m1 and replaced by mesofosset- tid in m2 during early ontogenetic stages. Mesofossettid of m1 absent when metaflexid begins to close.
