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.
|H. G. Seeley 1895||Temporal vacuities small. Cerebral region between them wide, and usually expanded above the brain-case. Skull bones are enormously thick; no interior cartilage to the brain-case. Palato-nares far forward. Occipital condyle singel, convex. Teeth with canines sometimes developed. Molar teeth pointed, convex in front, concave behind, with serrated borders, and a transverse inwardly developed ledge.|
