Folkeslunda Limestone

The Folkeslunda Limestone was deposited in an open marine environment with an estimated water depth of 150 to 200 metres (490 to 660 ft) in a eustatically transgressive phase.

Erratic blocks of the same formation are also found in Germany (Mecklenburg-Vorpommern) and along the Vistula River in Bydgoszcz and in Żary, Lower Silesia, Poland.

The southernmost Ordovician outcrops are situated in Skåne, due east of Lund and at the southeastern tip of Sweden.

[4] The Folkeslunda Limestone dates to the Lasnamägi stage, part of the Purtse, belonging to the Virunian in the regional stratigraphy of Sweden, corresponding to a late Darriwilian age of the Middle Ordovician.

Faunal differences with respect to the underlying formation were notes in the phosphatic brachiopod fauna, although the dominant species is the same as in the Seby Limestone.

Biostratigraphically, the Folkeslunda Limestone spans the Pygodus serra conodont zone and the Eoplacoghnathus reclinatus subzone.

The subzone index species is not common outside Baltoscandia but has been recorded from a few localities in eastern North America (Bergström 1973), Argentina (Albanesi & Ortega 2002), and China (Zhang 1998).
