Abstract
Ten species of phosphatic or phosphatised fossils are described from the Early Cambrian Todd River Dolomite of the Amadeus Basin in central Australia. The tannuolinid genus Micrina nov. is erected to include Platyceras etheridgei Tate 1892. The family Kennardiidae nov. is erected to include phosphatic organisms having three distinct forms of mitral sclerite. Assigned to this family are Kennardia reticulata gen. et sp. nov. and tentatively Dailyatia ajaxBischoff. Other phosphatic problematica are Paterimitra pyramidalis gen. et sp. nov., Eccentrotheca cf. kanesia Landing, Nowlan & Fletcher. Also described are phosphatised Chancelloria sp., Lenastella sp. and Pelagiella sp. and the phosphatic inarticulate brachiopods Askepasma toddensegen. et sp. nov., Edreja aff. distincta Koneva and ?Lingulella sp. Two species of tubular problematica are illustrated but not discussed in detail.
