Stenophragmidium Bassler, 1952 (Trepostomida: Bryozoa) from the Mississippian of Ireland and Britain

Abstract

Abstract:A reassessment of the rare trepostome bryozoan Stenophragmidium Bassler, 1952 from the Mississippian (Lower Carboniferous) of Ireland and Britain has utilised traditional morphometric methods as well as multivariate statistical methods, and allowed for the recognition of eleven species of this genus from this region. Full systematic descriptions are given of these taxa, which include the type species of the genus S. lobatum (Munro, 1912), six new combinations, and three new species S. ashfellensis, S. hibernicum and S. bundoranensis.
