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.
|C. B. Schultz and C. H. Falkenbach 1954||SKULL: Largest and most robust of genus; longer and wider than in holotype of D. curvidens; brain case more inflated than in D. curvidens; nasals moderately robust, with slight anterior retraction; anterior nasal- maxilla contact above diastema between C/ and P 1; infraorbital foramen above anterior portion of P 4 to anterior portion of M 1 ; squamosal more robust than in other examples of the genus; malar deep below orbit; post-glenoid process wide transversely.
MANDIBLE: Largest of genus; postsymphysis below Pa; inferior border of ramus with less downward curve than in examples of D. curvidens.
DENTITION: Series longer than in D. curvidens.
LIMBS:Approximately equal to examples of D. hatcheri geringensis. (Known from fragmentary remains only.)
