Diagnosis

Reference	Diagnosis
M. G. Lockley et al. 1995	Narrow sauropod trackway of medium to large size (footprint length about 50–90 cm), characterized by no space between trackway midline and inside margin of pes tracks. Pes footprint longer than wide with long axis rotated outward. Pes claw impressions, corresponding to digit s I, II and III show strong outward rotation. Manus tracks semicircular and small in comparison with pes tracks (i.e. pronounced heteropody).
C. A. Meyer et al. 2021	Narrow sauropod trackway of medium- to-large size (footprint length about 50–90 cm), character- ized by no space between trackway mid-line and inside margin of pes tracks. Pes footprint longer than wide with long axis rotated outward. Pes claw impressions corresponding to digits I, II, and III show strong outward rotation. Manus tracks semicircular and small in comparison with pes tracks (i.e., pronounced heteropody) (Lockley et al. 1994c).
