Diagnosis

Reference	Diagnosis
P.-E. Dieudonné et al. 2016	Rhabdodontomorpha is defined by the combination of the following synapomorphies (see phylogenetic analysis): 1) the maxillary process of the jugal is subrectangular and overlaps the maxilla with parallel dorsal and ventral margins, 2) the humerus shaft is strongly bowed from an anteroposterior view, 3) the ilium has a lateral deflection of the preacetabular process equaling or exceeding 30°, 4) the ilium has a dorsal margin of the preacetabular process transversely expanded to form a narrow shelf, 5) the dorsal margin of the ilium is mediolaterally thickened at the level above its ischiac peduncle, 6) the femur has a shallow and non-constricted trochanteris fossa on its proximal articular surface (not present in the more derived taxa Zalmoxes and Rhabdodon).
