Diagnosis
ReferenceDiagnosis
G. Billet et al. 2009Differs from A. patagonicus in: smaller size; smaller facial extent of the premaxillaries, not extending further posteriorly than the level of C; smaller number of teeth exhibiting simultaneously a fossette or fossetid (i.e. P3-M2 & p3-m2 in A. sunien- sis; P2-M3 & p2-m3 in A. patagonicus); more hypsodont cheek teeth, almost hypselodont; second mental foramen situated more anteriorly than in A. patagonicus; stylomastoid foramen situated closer to the tympanohyal recess.
