Abstract english

The impact of the Llandovery-Wenlock Ireviken Event (IE) on the jawed polychaete faunas is explored in this study, based on new data on scolecodonts from the Viki drill core of western Estonia. A distinct faunal reorganisation is observed, with the most abrupt changes recorded between datum points 4 and 6 of the IE, which coincides with the major turnover interval of other fossil groups. Based on what is now known, polychaetaspids and mochtyellids suffered most severely during the event, whereas the members of other families seem to have been less affected.
