The formation dates to the latest early to middle late Campanian stage of the Late Cretaceous and has provided fossils of ammonites, belemnites, the shark Cretalamna borealis and the mosasaurid Hainosaurus.

Ex situ occurrences in Pleistocene deposits have provided a dorsal vertebra of a possible elasmosaurid.

The Köpinge Sandstone has been recorded from a number of small outcrops, the majority of which are not accessible today, northeast of the town of Ystad, around Köpingemolla, Svenstorp, Valleberga, Ingelstorp, Herrestad and Fredriksberg.

[4][5] An isolated dorsal vertebra of a possible elasmosaurid was found in a Pleistocene Geschiebe, an ex situ occurrence of the Campanian formation, in southern Sweden.
