Common trace fossils observed in X-ray images of the two cores and illustrative cartoons that conceptualize the burrow morphologies. The trace fossils are classified under two main ethological classes, namely Deposit Feeding trace fossils: (a) Planolites (Pl); (b) Scolicia (Sc); (c) Less Dense Burrow (LDB); filling of the burrow is lighter that the surrounding material; (d) Lined Burrow (LB), has a distinct darker boundary; (e) Biodeformational Structure; and Chemosymbiont trace fossils: (f) Trichichnus/Mycellia-like Traces (Tr/My), dark filling indicates pyritized traces; (g) Chondrites (Ch); (h) Walled Tube Burrows. Tracefossil and burrow morphologies were traced out in CorelDRAW 2020.
