A review of the Cambrian biostratigraphy of South Australia
Cambrian rocks in South Australia occur in the Stansbury, Arrowie, eastern Officer and Warburton Basins. The succession in the Stansbury and Arrowie Basins can be divided into three sequence sets (supersequences), C1, C2 and C3. Sequence set C1 can be divided into five third-order sequences: C1.0, C...

Cambrian rocks in South Australia occur in the Stansbury, Arrowie, eastern Officer and Warburton Basins. The succession in the Stansbury and Arrowie Basins can be divided into three sequence sets (supersequences), C1, C2 and C3. Sequence set C1 can be divided into five third-order sequences: C1.0, C1.1A, C1.1B, C1.2 and C1.3. Trilobites from the Stansbury and Arrowie Basins are restricted largely to the lower part of the succession. Four trilobite zones are recognized: 'Abadiella huoi' (latest Atdabanian–earliest Botoman), 'Pararaia tatei', 'Pararaia bunyerooensis' and 'Pararaia janeae' Zones (all Botoman). Trilobites higher in the succession are known from only a few horizons and in part correlate with the upper Lower Cambrian Lungwangmiaoan Stage of China, equivalent to the top Toyonian. 'Pagetia sp.' has been reported in the Coobowie Formation of the Stansbury Basin, thus suggesting an early Middle Cambrian age. The Cambrian faunas of the Warburton Basin range in age from early Middle Cambrian (Late Templetonian) to very Late Cambrian, although the richest faunal assemblages are late Middle Cambrian ('Ptychagnostus punctuosus to Goniagnostus nathorsti' Zones).
