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.
