Early Ordovician Chitinozoa from Öland

The chitinozoans from fourteen localities through the Ontikan (Early Ordovician) strata of Öland, southeast Sweden, have been investigated. Fifteen species of the genera Conochitina, Cyathochitina, Desmochitina, Lagenochitina, and Rhabdochitina are described. Only one species, Lagenochitina tumida, has a restricted stratigraphical range.
