CAMBRIAN FOSSILS of South Australia and the sedimentary sequences in which they occur have been studied intermittently for over 100 years since Tepper (1879) recorded fossils from the Parara Limestone near Ardrossan on Yorke Peninsula.

Palaeobiological setting: the Cambrian explosion T h e a b r u p t a p p e a r a n c e, c l os e t o t h e boundary, of hard skele tal parts in metazoans, protists, and cyanobac teria, combined with a striking increase in the diversity and relative complexity of trace fossils, provides strong.

Bengtson in Bengtson et al. (1990) used Actino- theca Xiao and Zhou, 1984 as a generic name for decollating tubular fossils from the Terreneuvian to Cambrian Series 2. Because the name turned out to be occupied by a genus of tabulate corals Actinotheca French, 1889, Demidenko (2001.
The operculum of the problematic tubular fossil Cupitheca holocyclata Bengtson in Bengtson et a. (1990) is described for the first time based on collections from South Australia and North China.
Newly discovered trace and body fossils from the Grindstone Range Sandstone of South Australia reveal evidence of megascopic life on land during the Cambrian–Ordovician. Arthropod trackways (Diplichnites gouldi) are interpreted here to have formed on land. The most persuasive evidence for this view is that footprints vary in clarity along the length of the trackway as it traversed moist then dry silt, then biological soil crust.

Mackinnonia Runnegar in Bengtson et al is a widespread early Cambrian helcionellid mollusc known from China, Australia, Siberia, Greenland and North America (Parkhaev 2001, 2005; Skovsted & Peel 2007). The genus is characterized by a shell with a strongly undulating inner surface and straight outer wall (Runnegar 1990). Furthermore, a recent examination of fossils from the early Cambrian of Australia revealed calcitic semi-nacre in the Mackinnonia-like Parailsanella and foliated calcite in the paragastropod Pelagiella and other helcionellids tentatively identified as Bemella, Marocella, Figurina and Microconulus (to be treated in a subsequent publication).
