Excerpt:

“The Flinders Ranges of South Australia are famous for their fossiliferous early Cambrian faunas, especially their archaeocyaths, trilobites, early molluscs and sponges, among other fossil groups (e.g., Gravestock 1984; Bengtson et al. 1990; James and Gravestock 1990; Kruse 1991; Reitner 1992; Reitner and Mehl 1995; Skovsted et al. 2011). Most important are the fossiliferous Atdabanian– Botomian Ajax Limestone from the environs of the Mount Scott Range; and the more widespread, coeval Wilkawillina Limestone, which includes the Wirrealpa Mine area (31040 16.4800S; 138550 12.5400E) from where the material presented here derives. The standard view, first elaborated by Gravestock (1984) and later by Gravestock and Shergold (2001) based on the archaeocyaths, is that the Atdabanian-Botomian boundary within the Flinders Ranges is marked by the ‘‘Flinders Unconformity’’ (James and Gravestock 1990), a sequence boundary within the lower part of the Wilkawillina Limestone, separating the lower from the medial and upper intervals of the formation. This boundary is characterized by a decimeter thick ‘‘red crust’’ commonly bearing small up to decimeter-sized caves and crevices.” (…) READ MORE
