| The development of Skolithos trace fossils on the upper surface of some beds suggests periodical emergence into an intertidal zone. |
| Other marine trace fossils, together with marine bivalves, have been described from the unit as a whole. |
| This is based on the occurrence of trace fossils, principally on the abundance of intensely churned sediments there. |
| To avoid confusion with binomial nomenclature used in naming body fossils, trace fossils are named as ichnogenera and ichnospecies. |
| The oldest unequivocal trace fossils, mainly crawling trails, are also of Ediacaran age. |
| In addition any invertebrate fossils or trace fossils will be noted or collected if any new examples come to hand. |
