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.
|F. E. Peabody 1948||Relatively narrow, quadrupedal trackways indicating the normal tetrapod walking gait; in the walking gait a small pentadactyl manus impression regularly occurs immediately in front of, but never overlapped by a much larger, pentadactyl pes which generally resembles a reversed human hand. Manus and pes are digitigrade, and in large forms the pes tends to be plantigrade; digits I-IV point more or less forward, manus digit IV is always shorter than III, digit V is divergent and well developed as a crude prop for the foot; strong elaws are indicated on digits I-IV, infrequently on V of manus and pes, claw on III being largest; the footprints mayor may not show specialized metatarsal and phalangeal pads. Clear impressions often show a granular or beaded skin surface.
Reptiles represented by trackways probably dinosaur-like in form, and in body propor tions showed arrested tendency toward bipedalism. In smallest species pes only 3 cm.
