Global correlation of the early Cambrian of South Australia : shelly fauna of the Dailyatia odyssei Zone.
A lack of well resolved biostratigraphic data has prevented robust regional and global correlation of lower Cambrian successions from South Australia. A new early Cambrian biostratigraphy, based on data derived from 21 measured stratigraphic sections and drill cores (11 described herein) reveals the...
