Where: Namibia (27.3° S, 17.6° E: paleocoordinates 41.2° S, 172.9° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Nomtsas Formation (Nama Group), Ediacaran to Ediacaran (635.0 - 530.0 Ma)
• Ediacaran-Cambrian Boundary.
• formation-level stratigraphic resolution
Environment/lithology: offshore; lithified sandstone and siltstone
•Lower shoreface, just above SWB at its deepest, and tide-influenced on the basis of bidirectional paleocurrents and the presence of trough cross-bedding, based on sedimentary structures, including flaser to lenticular bedding and unidirectional current ripples (Fig. 9). Fine-grained sandstone with mud drapes was probably deposited by waning flows following storm or tidal flows, as described by Saylor (2003).
Size classes: macrofossils, mesofossils
