Eotitanops borealis Cope 1880

Authors/Creators

Description

Species Eotitanops borealis (Cope 1880)

= E. brownianus (Cope 1881) = E. princeps Osborn 1913 = E. major Osborn 1913?

Holotype: AMNH 4892, a right maxilla with complete P4 to M1 and fragmentary M2 to M3. Referred specimens: AMNH 296 (type of E. princeps), AMNH 4885 (type of E. brownianus), AMNH 14887 (Osborn's " neotype " of E. borealis), AMNH 14888, AMNH 14890, and AMNH 14891. Diagnosis: Large species of Eotitanops distinguished from E. gregoryi by its much larger size and lack of an entoconid on p4.

Discussion: Although many specimens were referred to Eotitanops borealis by Wallace (1980), the list of referred specimens in the present paper is limited to the type, Osborn's " neotype " skull of E. borealis, and the specimens that were used in the statistical analysis discussed above.
