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.
|B. L. Beatty 2009||Apomorphies of taxon: dental formula is 2.1.2?.3/1.1.1?.3;.
Differs from Behemotops in: molars with longitudinal rows of
columnar cusps that are closely appressed to each other; molars
lacking labial or lingual cingula; molars, specifically M3 and m3,
have styles/stylids in between the main cusps/cuspids, not large
enough to qualify as extra cusps themselves, and these styles/
stylids vary in size between left and right teeth; postorbital process
of the jugal; coronoid process of mandible is more strongly
posterior inclined. Differs from Paleoparadoxia in: molars lacking
labial or lingual cingula; molars with thicker enamel; postorbital
process of the jugal; juvenile mandibles have a posterior
thickening of the symphysis; coronoid process of mandible is
more strongly posterior inclined. Differs from Desmostylus in:molars brachydont; postorbital process does not contact the
zygomatic process of the squamosal since the zygomatic process
of the squamosal is not dorsoventrally expanded.
