Diagnosis
ReferenceDiagnosis
F. Bachmayer and R. W. Wilson 1970 (Protozapus)Approximate size of Sminthozapus janassyi. M1 larger than M2. Protocone of M1 and M2 united to mesocone-hypocone structures. Protocone of M2 transversely compressed, internal embayment shallow. Paracone of M2 connected more anteriorly to protocone, metacone connected more posteriorly to hypocone, than in most Plesiosminthus. m1 smaller than m2, chevron-shaped alignment of protoconid-metaconid; anteroconid small or absent. m2 with metaconid separated from protoconid by valley; protostylid spur absent.
