| Popis | Based on an analysis of the faunal composition, the palaeoenvironmental evolution of the section has been investigated. The sediments at the base of the section originate from a deeper marine basin and well oxygenated bottom waters. A first bryozoan event can be recorded in this interval. Above, foraminiferal evidence points to increased depth and decreased oxygen levels, coinciding with an abundance peak of molluscs and asteroids, but disappearance of bryozoans. In the upper half of the section, conditions changed considerably. Echinoderms and bryozoans exhibit high diversities in this interval. These drastic changes are related here to changes in basin geometry. |
