Diagnosis

Reference	Diagnosis
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.
