Fig. 3. A in An unusual trackway of a possibly bipedal archosaur from the Late Triassic of the Sichuan Basin, China

Fig. 3. A. Overview of the Late Triassic Fushun archosaur trackway. Stitched photograph (A 1), interpretative outline drawing (A 2), pace lines connecting the reference points (intersection of long and wide axes) of each track (A 3). Note that the reference point of FS-11 is ambiguous, because the foot was possibly sliding backwards into FS-10. B. Eosauropus trackway from the Utah West tracksite (Lockley et al. 2011: fig. 6). C. Eosauropus trackway from the Knowles Canyon tracksite (Lockley et al. 2011: fig. 6).

Fig. 6 in An unusual trackway of a possibly bipedal archosaur from the Late Triassic of the Sichuan Basin, China

Fig. 6. Comparison of the Fushun archosaur trackway with Pseudotetrasauropus, Otozoum, and Eosauropus. A. Outline drawing of the right pes FS-12 of the Fushun trackway. B. Pseudotetrasauropus bipedoida Ellenberger, 1972 (modified from D'Orazi Porchetti and Nicosia 2007: fig. 9). C. Otozoum moodii Rainforth, 2003 (mirrored and modified from Rainforth 2003: fig. 3C). D. Eosauropus cimarronensis Lockley, Lucas, and Hunt, 2006 (Lockley et al. 2006a: fig. 4A). In B 2, C 2 the gray-scale sketches show the connected outer edges; the black bars the length of the four digits. The digits of P. bipedoida are well separated while those of O. moodii are relatively compact. However, during foot withdrawal out of deep substrate, both could result in the anterior, elongated grooves as observed in FS-12, and these could correspond to digits III and IV.

Fig. 5 in An unusual trackway of a possibly bipedal archosaur from the Late Triassic of the Sichuan Basin, China

Fig. 5. Close-up photographs highlighting characteristic the Late Triassic Fushun archosaur track features. A. Photograph (A 1) and outline drawing A 2) of FS-5 exhibiting a large impression at the rear of the track, which is inclined towards the deepest part of the track, and a two elongated grooves in the anterior part of the track. The impression at the rear of the track is interpreted as being related to the foot sliding on the substrate into its final position, and the two elongated anterior grooves as toe and claw drag marks after foot withdrawal. B. Low-angle light photograph of FS-5 and FS-6. Note the two elongated grooves in the anterior part of FS-5, interpreted as toe and claw drag marks. C. Straight and washed out grooves between FS-6 and FS-7, and FS-7 and FS-8, interpreted as erosional dissolution features around roots and/or of draining water. Arrows indicate walking direction.
