Diagnosis
ReferenceDiagnosis
P. Ensom and D. Sigogneau-Russell 2000Lower molars differ from those of both Tinodon bellus and T. lepidus by their smaller size, the presence of posterior and anterior labial cingula, a less centrally acute lingual cingulum, and a lesser occlusal
angulation of the cusps.
