If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
R. Hoffstetter and M. Soria 1986 (Neodolodus)Didolodontidae a little smaller than D. multicuspis, half less than M. molariformis. Molar and premolar brachyodonts and bunodonts. P3P4 more elongated than in these two species; Highly advanced P4 molarization; A little less in P3, which is remarkably narrow and long; Paraconide present on P3 P4. M1-M3 without paraconide, but with a short preprotocristide: independent entoconide; No mesoconide, but a "cristida" obliqua as with Ernestokokenia. Dimensions (mm). - Length x width ant. (Trigonide) x post width. (Talonide): P3 8.2 x 4.2 x 4.5: P4b 7.5 x 5.2 x 5.6; M1 6.5 x 5.4 x 5.8; M, 7.5 x 6.2 x 6.5; M3 8.0 x 6.0 x 5.6. Length P3-M1 = 41.7.
