    Abstract

    The Röstånga-1 core from west-central Scania provides the most complete succession of the Sandbian (Upper Ordovician) through lower Telychian (Silurian, Llandovery) strata of southern Scandinavia. The Hirnantian is identified in the Kallholn Formation by the presence of a Metabolograptus persculptus Biozone fauna. The Akidograptus ascensus, Parakidograptus acuminatus, Cystograptus vesiculosus and Monograptus revolutus biozones can be differentiated in the Rhuddanian. Following a considerable gap (Demirastrites triangulatus Biozone to a level within the Pribylograptus leptotheca Biozone), the succession resumes. The Aeronian also includes the Lituigraptus convolutus and Stimulograptus sedgwickii biozones. The Stimulograptus halli Biozone appears to be missing, but the Telychian Spirograptus guerichi to Streptograptus crispus biozones have been recognized.
