Discinacean brachiopods from the Ordovician Kullsberg and Boda limestones of Dalarna, Sweden

Abstract

The poorly known species Orbiculoideal gibba (Lindström, 1880) from the upper Harjuan (Ashgill) Boda Limestone of Dalarna, Sweden, is redescribed, together with the new species, Orbiculoidea? kullsbergensis, from the upper Viruan (middle Caradoc) Kullsberg Limestone of the same province. A finely pitted post-larval ornamentation is described, which appears to be a feature common to many discinacean brachiopods.
