• "The lowermost part of the conformably overlying Clarens Formation (Figure 1(b, 3a)) is the main track-bearing unit at Tsikoane. It comprises laterally continuous, cream-coloured, sheet-like, fine- to medium-grained sandstones that range in thickness from 0.1 to 1.5 m (Figure 3(a)). These track-bearing, tabular sandstones are horizontally laminated and interbedded with green mudstone films (drapes) and layers (<0.2 m thick) that preserve desiccation cracks especially in the south-eastern part of the ichnosite (Figure 3(g)). In the north-western part of the ichnosite, a localised upward-fining unit comprises massive, intraformational, mud-pebble conglomerates at the base that gives way to interbedded green mudstones and grey and cream-brown, horizontally laminated, tabular, fine-grained sandstones (Figure 3(a, h)). Distinct U-shaped structures disrupt the interbedded part of this well-bedded, upward-fining unit (Figure 3(h)). The rest of the Clarens Formation at the Tsikoane ichnosite (Figure 1(b, 3a)) is characterised by 1 to 5 m thick, medium- to fine-grained sandstones that are mostly massive and rarely cross-bedded."
