Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. L. Cifelli 2004 | Small marsupial characterized mainly by its lack of derived characteristics with respect to other members of the cohort; molars structurally similar to those of Kokopellia. Differs from Pappotherium and Holoclemensia in: upper molars with protocone more expanded anteroposteriorly and transversely; postprotocrista extending past base of metacone; conules much more developed and with strong internal cristae; lesser height differential between paracone and metacone; lower molars with labial postcingulid present, entoconid more lingually situated, broader talonid, and lesser height differential between trigonid and talonid (presumed apomorphies). Differs from Kokopellia in: upper molars with bases of paracone–metacone more distinctly joined; stylar shelf with weaker, less cuspidate rim; M3 with postmetacrista directed labially (not posterolabially), ectoflexus much deeper, and anterior part of stylar shelf wider, with parastyle projecting in a more labial direction; lower molars with weaker labial postcingulid and with entoconid more lingually placed. Differs from Anchistodelphys and most other Late Cretaceous marsupials in the foregoing features and: upper molars with protocone more anteroposteriorly compressed (except Aenigmadelphys, Albertatherium) and conules placed closer to protocone; lower molars with weaker entoconid, less well-joined to hypoconulid. Further differs from Aenigmadelphys, Varalphadon, and most other Cretaceous marsupials in lacking a stylar cusp in the D position |
