Popis:	Two new placoderm taxa, based on isolated dermal plates from the head and trunk shields and body scales, are described from ?late Lochkovian (Early Devonian) limestones of the Connemarra Formation, central New South Wales. The taxa are Connemarraspis youngi gen. et sp. nov. and Narrominaspis longi gen. et sp. nov., for which the holotype specimens are ossified optic capsules. The fauna also includes several indeterminate acanthothoracids. All species were small fish, estimated to have been less than 10 cm long. This placoderm fauna shows a wide range of affinities, encompassing taxa with similarities to species from the Lochkovian of Arctic Canada, Europe and Vietnam.
