Orthoceras fossil in limestone, debris
- approximately 500 million years old
Ice masses spreading from the Baltic-Scandinavian region formed the relief of the landscape in the Quaternary period during the Weichselian glacial age, and brought large amounts of rock material of different types and sizes from Scandinavia and the Baltic Sea area into our region. This debris shaped the image of the ground and terminal moraine landscape. The larger pieces of rock, the boulders, also went into regional history. They were given names and some of them were connected with myths and legends.
Debris can be classified according to its creation, composition and origin. One group is composed of sedimentary debris. This was primarily created in bodies of water through the accumulation of sand, clay and silt. As individual rocks they contained fossilised remains of cephalopods, trilobites, brachiopods and molluscs. The red Orthoceras fossil in limestone can be found in Sweden. It was created during the Ordovician period and is approximately 500 million years old.
