The preservational processes of the trace fossils indicate soft substrate and diversity and their abundance reflects the other palaeoecological parameters of the open shallow marine environments.Īlpert, S.P. The trace fossil association indicates Cruziana ichnofacies and abundance of Zoophycus species below the fair weather wave base level is largely a preservational artifact. and somewhat irregular, obtuse angle ramification burrows of Phycodes isp., which are attached to the lower surface of the casting medium. Hypichnial structures consists abundant, cylindrical, branched, horizontal, large-sized three dimensional feeding burrows of Thalassinoides isp. and few suspension feeder forms like Palaeophycus tubularis while endichnial deep suites consist of Chondrites intricatus, Skolithos linearis and Zoophycos isp. 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. Dhosa Oolite Member of the Jumara Formation comprises alternating bands of oolitic limestones and shales, exposed in Jhura dome of Mainland Kachchh, Western India.
