Figure 2. Ediacaran trace fossils. (A) Archaeonassa isp., on bed top with prominent marginal levees demonstrating displacement of sediment. Ust Pinegia Formation, White Sea area, north-west Russia. (B) Bed top with Tribrachidium and Helminthoidichnites-type trace fossils preserved as natural casts as sand moved up to fill negative features on the bed sole. Ediacara Member, South Australia. (C) Stellate structure on bed top interpreted as a trace fossil comparable to Oldhamia. Ediacara Member, Chace Range, South Australia. (D) Bed sole with Dickinsonia preserved as an external mold at the end of a series of overlapping resting traces, preserved as low casts. Ediacara Member, Heysen Range, South Australia. (E) Field photograph of sinusoidal trace fossil Cochlichnus isp., on bed sole from the Huns Member, Namibia. (F) Treptichnus isp., on bed sole from the Huns Member, Namibia. Scale bars represent 10 mm in A, B, C, E, F; 20 mm in D.
