Diplichnites gouldi (Gevers, 1971)

Taxon description

Bradshaw, 1981

Description: Trackways of variable width between 20 and 220 mm consisting of 2 parallel rows of imprints, usually with undisturbed sediment inbetween (Fig. 29). The number of imprints across the width of the row is variable, never more than 5 and sometimes only 1. The imprints have simple, pit-like form and may merge to form composite prints (Fig. 30). Finer details are not preserved due to coarseness of sediment. The outermost imprints are invariably the deepest and those closest to the midline are the faintest. In 1 well-preserved trail (Fig. 31) 4 imprints are present across the row and appear to be arranged in closely spaced oblique lines. Although not included in Gevers et al. (1971) description of D. gouldi, median "tail" drag marks were observed in certain trails between 40 and 90 mm wide. The drag marks are usually present either as short median grooves, occasionally bearing deeper prod marks, or as isolated median pits. The individual walking imprints are indistinct in all trails with median marks, but are marked by small diagonal heaps of sediment pushed backwards as the animal moved forward (Fig. 32).
