Coiled nautiloids from the viséan of Ireland

Abstract

Species of the genera Subclymenia, Maccoyoceras (= Epidomatoceras Turner), Stroboceras, Epistroboceras, Phacoceras, Liroceras, Ephippioceras, and Knightoceras are described from on and near Dough Mountain, Co. Leitrim, Ireland, and from Cashel, Co. Fermanagh, Northern Ireland. Faunal associations are noted and the occurrence of species of Liroceras, Rineceras (= Pararineceras Turner), and Vestinautilus are recorded.

A new Early Carboniferous nautilid from the Caney Formation of Oklahoma, Central North America

“…However, the well developed lateral grooves in the adoral whorls of these species suggest that they are better referred to Stroboceras rather than Epistroboceras. Epistroboceras kathleenae Ramsbottom and Moore (1961) from Ireland does not belong to the genus Epistroboceras. Its almost circular whorl shape and six spirals (¼ longitudinal ridges) on the flanks suggest a possible relationship between E. kathleenae and Discitoceras (Hyatt, 1884).…”
