Abstract

Silurian discinoid brachiopods from Gotland currently housed in the Swedish Museum of Natural History in Stockholm are revised. Fourteen species of genera Schizocrania, Acrosaccus, Ivanothele, Orbiculoidea and Rugadiscina are described; three species (Acrosaccus barabackensis, A. hallaensis, and Rugadiscina petesviki) are new. Although generic composition of the Gotland discinoid fauna is very similar to that of the Welsh Borderland rather than to that of the Barrandian in Bohemia, the species differences confirm a biogeographic separation of all these areas in the Silurian.
