Diagnosis
ReferenceDiagnosis
B. M. Davis and R. L. Cifelli 2011Moderate−sized deltatheroidan differing from all other deltatheroidans in relatively larger talonid; differs from all other deltatheroidans except Atokatheridium in narrower stylar shelf; differs from other deltatheroidans except Sulestes in less height differential between paracone and metacone, metacone broader than paracone, prominent conules, mesiodistally broad protocone, and presence of entoconid; differs from Atokatheridium in larger size, larger stylocone, and relatively larger metaconid; differs from Sulestes in wider protoconal region; differs from Deltatheroides in stronger reduction of metacone and metastylar lobe on M4.
