Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| I. A. Vislobokova 2001 | Skull brachycephalic, with snout weakly elongated. Orbits small, in anterior posi- tion, and apparently open posteriorly. Foramen ovale small and more anteriorly positioned than in archaeomerycids. Alisphenoid and pterygoid canals absent. Postglenoid process present. Postglenoid foramen small, circular, and not enclosed by bulla. Auditory bulla small, in contact with postglenoid process. Exter- nal acoustic meatus very short but longer than in archaeomerycids. Stylohyoid vagina shallow and widely open posteriorly. Petrosal placed closer to parasagittal plane than to horizontal one and pressed against basioccipital and alisphenoid. Promontorium, fenestra vestibuli, and stapedial muscle fossa similar to those in archaeomerycids. Lateral wall of epitympanic recess formed by squamosal. Mastoid exposure lateral. Lacrimal with very short facial part and single lacrimal foramen on antorbital rim. Jugal high with short ante- rior process. Palate concave, median border of palate almost straight and located opposite M3.. Posterior opening of infraorbital canal located in maxilla. Mandi- ble slightly descending anteriorly with long symphysis, posteriorly projected angular process, and semivertical anterior border of coronoid process. Upper canines large. Lower canines incisiform. P I absent; p i small and detached. Other premolars elongated and weakly molarized. Lower p410nger than mI. Lingual crescents of lower molars weakly developed. Dorcatherium fold absent. Radius and ulna, tibia and fibula, and central metapodials separate. Distal end of fibula reduced to malleolar bone. Astragalus double-pulley, with nonpar- allel trochleae. Metapodials separate. |
