Mammalia - Eutriconodonta - Amphilestidae
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. -D. Heinrich 1998||Known only from a double-rooted cheek tooth, tentatively identified as right lower molar. Tooth crown linguolabially compressed, elongated, without mesial indentation, with three main cusps (a, b, c), and two basal cusps (d, e). The cusps are arranged mesiodistally, and they are closer to the lingual margin of the tooth crown than to the labial. The cusp formula reads a > c > b > d > e. The principal cusp a is substantially larger than the main cusps b and c. Main cusp c is situated at a higher level than b. Except for very faintly developed anterolingual and anterolabial cingula, which are located below the cusps b and e, well-defined cingula are lacking. The cross sections of the roots are anteroposteriorly elongated.|
