Chitinozoan stratigraphy and palaeoecology at the Ordovician–Silurian boundary in Skåne, southernmost Sweden

The chitinozoan fauna at the Ordovician-Silurian boundary in Skåne is poor, with only four species. The two genera Ancyrochitina and Conochitina are almost mutually exclusive. This is useful when correlating the boundary in Skåne. It is concluded that Conochitina had a benthic and Ancyrochitina a planktic mode of life.
