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.
|B. J. González Riga and J. O. Calvo 2009||Sauropod tracks of medium size (footprint length abut 50 cm) characterized by a wide-gauge trackway [manus and pes trackway ratios (MTR and PTR) of 18–22 and 26–31 per cent respectively]; manus tracks without claw impressions and strongly rotated outward (25–48 degrees), with asymmetrical crescent shape and acuminate and thinner external border; pes tracks with subtriangular to subcircular shape, longer than wide, and rotated slight negative (outward); pronounced heteropody (manus ⁄ pes area ratio of 1:3); outer limits of trackway deﬁned, in some cases, by manus tracks; manus-pes distance about 1.7 times pes footprint length; stride length around 4.9 times pes track length; step angle 92–110 degrees; tail drag marks absent.|
