Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. P. Wilson et al. 2007 | Autapomorphies of Dakshina: multiple-layered dental enamel (Patnaik et al., 2001), at least one molariform position with a V-shaped enamel islet. Differing from Gondwanatherium and Sudamerica in: dental enamel with well developed inter-row sheets of interprismatic matrix (Krause et al., 1997; Koenigswald et al., 1999; Patnaik et al., 2001), molariforms with perikymata, deep infundibula (Koenigswald et al., 1999), and vertical furrows only on lingual side of crowns. Differing from Gondwanatherium in: vertical furrows extending to base of molariform crowns (Krause et al., 1997). Differing from Sudamerica in: molariforms gently tapered towards the occlusal surface. Differing from Lavanify in: molariforms without a V shaped dentine lake, with enamel on all sides of crown (Krause et al., 1997). |
