A diverse Hirnantian scolecodont assemblage from northern Estonia and resilience of polychaetes to the end-Ordovician mass extinction
Original language description
We report the discovery of a rich assemblage of latest Katian and Hirnantian scolecodonts (poly -chaete jaws) from a new Ordovician-Silurian boundary outcrop in the Reinu quarry, northernEstonia. The recovered polychaete fauna contains at least 40 species attributed to 11 families. Manycommon taxa appear to range from the latest Katian to the Hirnantian and into the Rhuddanian,indicating the resilience of jawed polychaetes to the end-Ordovician mass extinction. The Reinuassemblage is similar to the coeval faunas known from other Baltic sec tions, as well as fromAnticosti Island, Canada, although with some specific features. The study revealed the highestabundance of scolecodonts in the Ordovician of Baltica, with ca 5400 maxil lae per kilogram ofrock recorded in the Siuge Member of the Ärina Formation, Porkuni Regional Stage, early Hirnantian.
