“Nine species of Virgilian (Late Pennsylvanian) coiled nautiloids are described from the Finis Shale Member of the Graham Formation in north-central Texas, southern Midcontinent of North America. They include Tainoceras monilifer Miller, Dunbar and Condra, Metacoceras quadratum sp. nov., Endolobus sturgeoni sp. nov., Domatoceras tuckeri sp. nov., Titanoceras sp., Solenochilus jackense sp. nov., Liroceras liratum (Girty), Peripetoceras bridgeportense Tucker and Mapes, and Ephippioceras ferratum (Cox). The habitat of the nautiloid assemblage was the low latitudes in the Marginal Sea of the Panthalassic Ocean. Strong biotic linkage between the Marginal Sea and the southern Late Pennsylvanian Midcontinent Sea is confirmed.” Free download of the PDF
