Lower Devonian brachiopods from the Point Hibbs Limestone of Western Tasmania

Abstract

Fourteen brachiopod species belonging to the following genera are described from the middle Lower Devonian (Siegenian) Point Hibbs Limestone, Tasmania: Schizophoria, Isorthis, Cymostrophia, Megastrophia, Hipparionyx (?) ,"Chonetes" Machaeraria, Uncinulus, Hebeotoechia, Atrypa, Meristella, Athyris, Cyrtina, and Acrospirifer. Megastrophia hillae sp. nov., Hebeotoechia hibbensis sp. nov., and Acrospirifer banksi sp. nov. are erected. This fauna displays close affinity to faunas recorded from the Coopers Creek Formation, the Lilydale Limestone, and the Tabberabbera Formation of Victoria, and the Baton River Beds of New Zealand.
