Diagnosis
ReferenceDiagnosis
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.
