Phosphatic and phosphatised organisms, mainly elements of multisclerite forms, tubes, and inarticulate brachiopods, have been found in predominantly dolostone formations in three widely separated areas of central Australia: the eastern Amadeus Basin, and the Huckitta and Marqua-Hay River regions of the Georgina Basin. The faunas are of similar composition and age in the three areas, and permit lithological correlation of the Todd River Dolomite, the Errarra Formation, and the Red Heart Dolomite of each area, respectively. They also permit correlation with the more diversely fossiliferous sequences of the Flinders Ranges of South Australia, and indicate that these may be younger than previously thought.
