Abstract
Isolated chitinozoans from the Scorn Shale Member of the Cedarberg Formation, SW South Africa are described and provide,I date of the latest Hirnantian-earliest Rhuddanian. The recovered chitinozoans are typical of the latest Ordovician Spinachitina oulebsiri Biozone, although an earliest Silurian age is possible. They indicate a very short time span (less than 1 Ma) across the Ordovician-Silurian boundary. This is currently the highest biostratigraphical resolution attainable for the Scorn Shale Lagerstatte. Correlation of the Soom Shale chitinozoans with identical assemblages in post-glacial, transgressive deposits of Northern Africa is possible; both faunas occur in shales that overlie glacial diamictites of the Hirnantian glaciation. A new species, Spinachitina verniersi n. sp. is described. lJ. Micropalaeontol. 28(1): 53-66, May 2009.
