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.
|R. T. McCrea and W. A. S. Sarjeant 2001||Footprints of small to large size, showing three digits united proximally, most often in a metatarsal pad ("heel"); webbing and hallux lacking. Digits slim, their maximum width less than 15% of their length; digit III is more than 25% longer than the lateral digits. Total interdigital span greater than 95° and often exceeds 120°. Length of digits II and IV may be similar, but digit IV is frequently somewhat longer. All digits clawed, the claws frequently showing inward flexure in relation to the digit axis. Digital pad impressions may be visible on better-preserved molds or casts—three to four on digit III, two on digits II and IV.|
