Diagnosis

Reference	Diagnosis
A. A. Carlini et al. 2006 (Mirandabradys)	Large-sized mylodontoid. Skull profile with a marked angle between the rostrum and braincase. Molariforms with some transverse elongation except the last one. Femur with the diaphysis only slightly narrower distally than proximally, widening slightly up to the level of the trochanter minor and anteroposteriorly compressed; trochanter major large and massive; third trochanter developed on the lateral margin, slightly below the midpoint of the diaphysis and continued distally as a laminar area that merges with the ectepicondyle. Tibia and fibula seem proximally and distally immobilised. Tibia without marked torsion in contrast to Quaternary Mylodontinae.
