Diagnosis
ReferenceDiagnosis
P. A. Holroyd and R. L. Ciochon 2000Differs from all other brontotheriids in having: moder- ately crenulate enamel present on the lingual surfaces of the upper mo- lars and in the basins of the lower molars; lower crowned lower molars in which the talonid is relatively longer than the trigonid, the preme- tacristid is absent, and the cristid obliqua meets the protolophid near the midline of the tooth rather than connecting with the metaconid and postmetacristid. Differs from more advanced brontotheriids such as Mi- crotitanops, Protitan, Pygmaetitan, Sivatitanops, and Metatelmatherium in having: relatively shorter and wider upper molars with larger para- conules, more poorly developed buccal shearing crests that do not curve lingually, relatively higher lingual cusps with better developed crests, larger and more anteriorly positioned hypocone with strong prehypocone crista. Differs from more primitive brontotheriids such as Eotitan- ops, Palaeosyops, and Telmatherium in having a better developed hy- pocone, relatively smaller and more anteriorly positioned paraconule.
