FIG. 12 in New remains of kollpaniine "condylarths" (Panameriungulata) from the early Palaeocene of Bolivia shed light on hypocone origins and molar proportions among ungulate-like placentals

FIG. 12. — Raulvaccia peligrensis: left M2 (cast of MLP 90-II-12-70) in occlusal view. Comment: we tentatively refer this tooth to an M2 (contra Gelfo 2007, who refers it to an M1?) because of the mesiolabial position of the paracone (as related to metacone), which provides to the tooth a distinct asymmetrical morphology as is observed on the M2s of Molinodus and Simoclaenus but not on the M1s of these taxa. Scale bar: 5 mm.
