Diagnosis
ReferenceDiagnosis
G. G. Simpson 1934An early suborder of Notoungulata, including some primitive, rather generalized forms and a few ancient divergent lines superficially specialized but basically primitive.
Dentitioncompleteorwith I3CG1P- variouslyreduced. Allcheekteethbrachyo- dont,withoutcement. Upperpremolarsprogressivelycomplicated,butalltriangular or nearly so, with protocone at least on p2_4 and hypocone very feeble or absent. Upper molars transverse, with strong parastyle, well formed ectoloph and oblique protoloph,butmetalophvariableandoftenimperfect. Crochetpresent,anteropos- teriorwhenelongated,andgenerallyfreeofectoloph. Othersecondaryfoldsorcrests slightorabsent. M1_2quadrate,withstronghypocones,nearlyorquiteequaltopro- tocones.

Trigonidessentiallyasingletransverse lophid, anterior wing reduced, paraconid inconspicuous and median or relatively external. Talonidswithastrong,elongate,crescenticlophidandsimple,transverse,

Zygomataarisingoppositeanteriormolars. Cranium(Notostylopidae,unknownin other families but probably similar) markedly triangular between squared zygomata. Strongpostorbitalconstriction. Endocranialcastmuchinastypotheres,butmore primitive. Earregionofgeneralizednotoungulatetype,epitympanicsinusrelatively small, porus low, ossified meatus short and nearly horizontal, tympanic crested, hypotympanic sinus large and globular, extending far ventral to basisphenoid, cranio-facial flexion slight.
Mandible rather elongate and slender, tooth series nearly straight.
