Kalobatippus agatensis
Taxonomy
Kalobatippus agatensis was named by Osborn (1918). Its type specimen is AMNH 14211, a partial skeleton (A lower jaw associated with vertebrre, limb bones, and fore and hind feet), and it is a 3D body fossil.
It was recombined as Anchitherium agatensis by Romer (1926), Simpson (1932) and Stirton (1940); it was considered a nomen dubium by Macdonald (1992).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. F. Osborn 1918 | (Matthew, 1913) (1) Teeth with higher crowns than in Kalobatippus praestans; (2) premolars relatively 10% broader; (3) anterior lobe of J>2 relatively narrower, with atrophied antero-external cingulum; (4) entoconulid of m3 with distinct cusp; (5) external cingula vestigial or absent; (6) postcanine diastema one-third shorter thanK. prrestans; (7) symphysis shorter, more massive, incisors more robust. (8) Magnum-Mtc. II, articulation narrower; (9) feet about one-eighth larger in all dimensions. The type and cotype include lower jaws of two individuals in slightly different degrees of wear which unquestionably pertain to the same species. With one of the jaws is associated a considerable part of the skeleton, all of one individual, including the cervicals except C 2-3, D 2-9, also three posterior dorsals, L 1, and part of S 1, a few ribs, scapulre, pelvis, humerus, most of both radii and uhire, magnum, Mtc. II, III of both sides, 1st median phalange of fore foot, distal part of femur, one hind foot nearly complete, and parts of the other. |
