At Red Bluff‚ the Tumblagooda Sandstone in this section is different to the Tumblagooda Sandstone found at Natures Window‚ and thus‚ the deposition environment is different. Red Bluff was most likely deposited in a fluvial-intertidal environment (shallow waters) as indicated by the high abundance of skolithos trace fossils‚ skolithos generally reside in shallow waters (refer to notebook‚ page 58). The higher abundance of trace fossils in the upper section of the sandstone than the lower section suggests
