Diagnosis
ReferenceDiagnosis
G. G. Simpson 1932A Patagonian fossil mammal of uncertain afinities. Upper molariform teeth with subequal, well separated paracone and metacone. Protocone and hypocone about equal, partly connate (more anteriorly )to well separate. Proto-and metaconules almost as large as proto-and hypocones and tending to form cross crests with the latter and the para and metacones. Metaconule partly connate with hypocone and not at all with protocone. No mesostyles. Anterior and posterior, but no internal, cingula.
