Diagnosis
ReferenceDiagnosis
W. G. Joyce and T. R. Lyson 2015Neurankylus lithographicus is currently diagnosed as a baenid by presence of a processus trochlearis oticum, axillary and inguinal buttresses that reach the costals, lack of epiplastral processes and the development of mesoplastra, and as a repre- sentative of Neurankylus by its large size, smooth shell that lacks both anterior and posterior notches, complete ring of marginals, wide vertebrals and a small, undivided cervical that is taller than wide. Neurankylus lithographicus is currently differentiated from all Neurankylus by a wide vertebral V, extragulars that are smaller than the gulars and that contact one another along the midline and the lack of a posterior scalloped shell margin.
