Diagnosis
ReferenceDiagnosis
R. Royo-Torres et al. 2021It can be diagnosed by one autapomorphy (marked with an asterisk), as well as a unique combination of derived diagnostic characters: (1) middle-anterior caudal vertebrae with an asymmetric lateral fossa set in a posterior position (*); (2) longitudinal ridge on the lateral face of the pubis, from the anterior area of the obturator foramen to its distal end; (3) perpendicular angle between the ischial articulation and posterior pubic symphysis of the pubis; (4) the distal end of the pubis presents an obtuse angle between the ventral and anterior surfaces in the lateral and medial views; and (5) outwardly developed triangular lateral trochanter of the fibula, which is visible in the anterior and posterior views.
