Diagnosis
ReferenceDiagnosis
G. Edmund and J. Theodor 1997A small pampathere , slightly larger than Vassallia minuta, but smaller than Kraglievichia paranensis. General features of skull resemble those of other pampatheres. Anterior four upper teeth generally cilindrical. M4 elongate-ovate. Teeth M5 to M8 clearly bilobated, with emarginations on the medial side in some specimens; M9 varies, often reniforme or egg shaped. Mandible relatively shallow dorsoventrally, elongated; ascending ramus broad anterpposteriorly. Lower dentition resembles upper. Skeletal elements almost identical with those of other pampatheres. Two facets of the astragalo-calcaneal articulation well separated. Osteodrems approximately the size of V. minuta; half are hexagonal in outline. Typical buckler osteoderm has a small number of well-spaced follicular pits connected by distinct channel. Submarginal band continuos, confluent posteriorly with alongate central figure.
