targionii, Planolites beverleyensis, Taenidium cameronensis, Thalassinoides isp., Z. The endichnial shallow suites consist chiefly of deposit feeders like Chondrites intricatus, C. The endichnial structures within the oolitic limestone can be separated into two different preservational trace fossil suites. irregulare, Zoophycos brianteus and Zoophycos isp. Epichnial tiering consists of moderately bioturbated oolitic limestone exhibiting horizontal or low-angle protrusive/retrusive biogenic laminae, commonly dominated by feeding structures like Rhizocorallium jenense, R. The rhythmically bedded sequence shows three different levels of preservation of traces. This sequence is highly bioturbated and exhibits a moderate diversity and behaviourally complex assemblage of ichnospecies.
