'Most Early Permian tetrapods are holdovers from the Late Carboniferous. They identify a single paleobiogeographic province (the edaphosaurid empire of Anderson and Cruickshank [1978]or the edaphosaur-nectridean province of Milner [1993]) from the southern region of Euramerica close to the paleoequator. Lepospondyls, anthracosaurs, seymouriamorphs, cotylosaurs and a variety of pelycosaurs are characteristic Early Permian tetrapods..' (Lucas, 2004). 'The microsaurs Carrolla and Pariotichus, and the pelycosaurs Ctenospondylus and Eothyris, are restricted to the Seymouran. However, none of these taxa are abundant or widespread enough to be robust index taxa. The FADs of Protocaptorhinus, Seymouria, Varanosaurus, Secodontosaurus and Araeoscelis, and the LADs of Parioxys, Platyhystrix and Sphenacodon, also distinguish the Seymouran LVF' (Lucas, 2006)				comp notes
