Toko makes a good point about the enlargement of tracks in sand when the sand is deep. loose (usually warm) and dry and its good to consider any alternatives. However the area where these tracks were found is outside the Namib sand belt which lies to the south and west. This is on the gravel plain below the escarpment where finer sand grains have been largely blown clear leaving behind a relatively hard surface. In the uncropped original photo my boots left barely discernable imprints next to the rhino prints. The hard surface easily supported my weight and I don;t believe a 200 kg gemsbok would leave such deep prints. Perhaps a running gemsbok, but these prints are too close together to support a running animal Also the outline of the tracks are more distinct than loose, soft sand would support, there isn;t the amount of inflow you might see on the side of a dune. And if my memory is correct, gemsbok hooves are 5-6cm wide - only about 1/3 the width of the photo prints.
