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.

E. Hitchcock 1848 (Anisopus)Quadrupedal; hind feet nearly twice as long as the fore ones, and considerably wider. Both hind and fore feet four-toed. In walking, the hind foot was brought up nearly into the place of the fore one. Tracks but a little to the right and left of the line of direction. Foot pachydactylous.
E. Hitchcock 1848 (Macropterna)Hind feet four-toed; fore feet three to four-toed. Heel long, especially upon the hind feet. Fore feet usually digitigrade, and much smaller than the hind ones. Hind feet usually plantigrade.
E. Hitchcock 1858 (Arachichnus)Four or five-toed, the toes radiating in all directions, especially on the hind feet. Lines also diverge from the track longer than the toes, in two and sometimes three directions, which are acuminate like the toes, but evidently not toes.
R. S. Lull 1904 (Sustenodactylus)Quadrupedal, digitigrade; pentadactyl manus and pes. Digits extremely slender and tapering, without claws or pads. Pes about twice the size of the manus.
