Fig. 3A, B View Fig .
Holotype: BMNH J.526, a right lower molar.
Derivation of the name: kirtlingtonensis , provenance of the described material.
Molariforms.—BMNH J.784 (left), J.804 (right),?J.333 (left);?J.456 (left, last pm or milk),?J.778 (left),?J.796 (left, milk).
Distribution.—Clay Band, Kirtlington mammal bed in Forest Marble; upper Bathonian.
Diagnosis.—Lower molars differ from those of all other docodont genera (?except Tegotherium Tatarinov 1974 ) by the depth of the lingualand distalfurrows of the main cusp, and by the posterior crest of the talonid, which bears three cuspules. Mesio−lingual cusp well developed. Moreover, differs from Simpsonodon , which also has a high development of lingual cusps, by a relatively higher main cusp, an even wider and deeper pseudo−talonid, and the lack of a lingual cingulum. Differs from Borealestes by the development of the mesio−lingual cusp, the pseudo−talonid and the limited extension of the anterior crescent, somewhat of the same extent as in Docodon . Differs from Docodon by the pseudo−talonid, the development of the mesio−lingual cusp, the lack of antero−posterior compression of the various cusps and the absence of “the complicated pattern of furrows and ridges” (Simpson 1929: 91). Possibly synonymous with Tegotherium (see discussion below).
