| 1a. Unbioturbated, laminated ichnofabric |
No bioturbation recorded and sediment laminations are distinct. Rare ostracods and crinoids are recorded. Some laminations record subtle bioturbation (II2). |
| 1b. Unbioturbated, massive ichnofabric |
Structureless fine sandstone frequently with subcentimetre mud clasts forming thin horizons within the fabric. Occasionally, some rare indeterminate vertical traces and Chondrites. |
| 2. Vertical indeterminate traces ichnofabric |
Dominantly bioturbated by vertical indeterminate traces. The vertical indeterminate traces look similar to the probable pedicle traces associated with lingulid brachiopods (see Zonneveld, Beatty & Pemberton, 2007). Other ichnofossils include: Arenicolites, Chondrites, Diplocraterion, Teichichnus, and Lingulichnus. |
| 3. Teichichnus ichnofabric |
Alternations of courser beds that are either fine sand or randomly orientated shell material with silt to very fine sandstones that are highly bioturbated by Teichichnus. Less common traces include Rhizocorallium, Chondrites, Skolithos, vertical indeterminate fossils, and Planolites. |
| 4. Chondrites-Teichichnus ichnofabric |
Alternating 1–3 cm beds of unbioturbated fine sand and silt to very fine sand. The finer sediments are dominantly bioturbated by Chondrites and occasionally extend into the underlying fine sand. Teichichnus cross-cuts the Chondrites burrows. All burrows are shallow tiering (1–3 cm depth). |
| 5. Rhizocorallium-Chondrites ichnofabric |
Bioturbated but bedding distinct. Rhizocorallium and Chondrites alternate and are the dominant bioturbators. Rhizocorallium does not cross-cut other traces and occasionally Chondrites cross-cuts the Rhizocorallium traces. |
| 6. Rhizocorallium ichnofabric |
Highly bioturbated fabric dominated by relatively large Rhizocorallium traces. Burrow depths exceed the sample size. The Rhizocorallium burrows cross-cut everything. Less common traces include Arenicolites, Chondrites, Teichichnus, and Planolites. |
| 7. Chondrites-Diplocraterion ichnofabric |
Moderately bioturbated. Dominated by Chondrites and Diplocraterion, where Chondrites typically cross-cuts other traces. Less common traces include Rhizocorallium, Skolithos, and Planolites. |
|
8. Chondrites-Rhizocorallium ichnofabric |
Highly bioturbated and dominated by Chondrites and to a lesser extent Rhizocorallium, where Rhizocorallium cross-cuts the Chondrites burrows. Less common traces include Lingulichnus, Planolites, and Teichichnus. |
| 9. Chondrites ichnofabric |
Highly bioturbated fabric dominated by Chondrites, which also typically cross-cuts other ichnofossils. Less common traces include: Rhizocorallium, Diplocraterion, Planolites, and Teichichnus. |
