Abstract
Two new stromatolites, Ephyaltes edingunnensis and Eucapsiphora leakensis, are described from the Palaeoproterozic Earaheedy Group, in the Earaheedy Basin (formerly the eastern part of the Nabberu Basin), Western Australia. In addition, new localities are reported for Asperia digitata comb. nov. (= Yelma digitata Grey 1984), Pilbaria deverella Grey 1984, and Yandilla meekatharrensis Grey 1984 from problematic successions in the adjacent Glengarry Basin (formerly the western part of the Nabberu Basin), confirming correlation of these rocks with the base of the Earaheedy Group. Four of the five groups recorded, Asperia, Eucapsiphora, Ephyaltes and Pilbaria, are known from outside the Earaheedy Basin and their stratigraphic age is consistent with the probable minimum 1.65 Ga age of the Earaheedy Group. However, none of the forms has yet been recorded from outside the Earaheedy Group.
