Diagnosis
ReferenceDiagnosis
E. H. Lindsay 1987Democricetodonts are characterized by m1 having a wide and weakly bilobed anterocone (medial lobe much smaller than labial lobe); upper molars commonly have more than one loph directed and frequently joining the opposing cusp; posterior molars are slightly reduced in size esecially in the lower dentition. In addition, the longitudinal crest (mure) is very persistent and the mesoloph (mesolophid) is commonly present by short in all molars.
