Mammalia - Proboscidea - Palaeomastodontidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|W. Sanders et al. 2004||Large species of Phiomia; molar size range surpasses dimensions of Fayum palaeomastodonts and symphysis and incisors much longer than in Palaeomastodon and other species of Phiomia (Table 3; Fig. 12); further distinguished from Palaeomastodon by absence of posttrite cristae (“zygodont crests”), presence of a central conelet in the posterior loph of P4, and by full trilophodonty of molars, including M3/m3. Differentiated from Miocene elephantoid taxa (for example, Hemimastodon, gomphotheres, mammutids) by smaller size of molars (Fig. 12), lack of features such as zygodont crests, crescentoids, and pretrite anterior and posterior accessory central conules throughout the crown, and trilophodont m3 with a diminutive posterior cingulid. Distinguished from Moeritherium by larger size, development of incisors into tusks, and trilophodont intermediate molars.|
