Abstract
The latest Proterozoic to Early Cambrian sequences of the Amadeus and Georgina Basins of central Australia have yielded abundant and diverse trace fossils. Those of the Arumbera Sandstone are particularly significant because recent studies of that unit have shown that it is lithologically uniform and spans the Proterozoic-Cambrian boundary with no discernible break. In our studies of this and other units we have been able to distinguish four assemblages of trace fossils forming a succession that we interpret as due to the evolution of bioturbating animals. The lowest strata examined occur immediately above the upper of the two Proterozoic glacial units that are widespread in Australia and comprise the Grant Bluff and Elyuah Formations of the Georgina Basin and the lower Pertatataka Formation (Cyclops Member and below) of the Amadeus Basin. These units lack definite trace fossils, despite having lithofacies comparable with those containing traces higher in the sequence. The probable fossil medusa Bunyerich...
