Also known as Wilkawillina Limestone, base of MMF, ~11 km east of Blinman
Where: South Australia, Australia (31.2° S, 138.9° E: paleocoordinates 16.8° N, 161.2° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Abadiella huoi trilobite zone, Mernmerna Formation, Atdabanian (521.0 - 516.0 Ma)
• Complete stratigraphy in Paterson and Brock (2007). Abadiella huoi Zone. The occurrence of Elicicola calva at the base of the MMF section is taken to represent the A. huoi Zone. This is further supported by the co-occurrence of the paterinid brachiopod Askepasma in the same horizon (i.e., MMF/0.0)
•
•This is informally called “Parara” but is Atdabanian equivalent.
• bed-level stratigraphic resolution
Environment/lithology: wackestone and packstone
Size classes: macrofossils, mesofossils, microfossils
• isolated sclerites; multisclerite fused composites
Preservation: original phosphate, original silica
Collection methods: acetic
