Diagnosis
ReferenceDiagnosis
J. Mo et al. 2007Nanningosaurus dashiensis is distinguished from all other hadrosaurids by a unique combination of derived and primitive features: tall and sharply peaked dorsal process of the maxilla with reduced process of the jugal and a distinct lacrimal facet, gracile humerus with low, rounded deltopectoral crest, mandibular condyle of the quadrate transversly broad with weakly developed paraquadrate notch, dentary tooth with sinuous median carina and subsidiary ridge, relatively few tooth positions, and ischial shaft straight along most of its distance, but to curve dorsally and expand at the distal end before the ischial foot begins.
