摘要
A new species of cervid, Euprox altus, from the Middle Miocene fossil locality of Damiao, Siziwangqi, Inner Mongolia, is described and studied in detail. It is assigned to Euprox based on its true burrs, bifurcation above the burr, long pedicles, brachyodont cheek teeth, developed parastyle and mesostyle, neocrista and cingulum on each upper molar, developed metaconid and hypoflexid on p4 and palaeomeryx folds on lower molars. The diagnostic character of E. altus is that the bifurcation begins at a higher position than in other species. The presence of E. altus may indicate a warm and humid environment during the latest Middle Miocene in the Damiao area, in sharp contrast to the current dry and harsh environment.
