Ordovician chitinozoa from the Stora Asbotorp Boring in Västergötland South-Central Sweden

Ordovician Chitinozoa have not been described previously from Västergötland. In the Stora Åsbotorp boring, situated in the northeast part of the Billingen Plateau, 24 species from 6 genera have been recorded from Ordovician strata. The Chitinozoa are compared with those from Öland and Dalarna (Dalecarlia) and show great similarity with the chitinozoans from Öland. Angochitina communis is reported from the Baltoscandian area for the first time. Chitinozoan palaeoecology is briefly discussed.
