kivikerrokseen

Kivikerrokseen is a geological formation found in the Baltic region, particularly in Estonia, Latvia, and Lithuania. It is a layer of sedimentary rock that was deposited during the Late Ordovician period, approximately 444 million years ago. The term "kivikerrokseen" translates to "stone layer" in English, reflecting its composition of sandstone, siltstone, and shale.

The formation is notable for its fossil content, which includes a diverse range of marine organisms such as trilobites, brachiopods, and corals. These fossils provide valuable insights into the paleoenvironment and the evolution of life during the Ordovician period. The kivikerrokseen also contains evidence of ancient volcanic activity and tectonic movements, which contributed to the deposition of the sediments.

The kivikerrokseen is of significant geological interest due to its well-preserved fossils and the information it provides about the Earth's history during the Ordovician. It is also a popular destination for geologists and fossil enthusiasts, who study the formation to better understand the ancient ecosystems and geological processes that shaped the Baltic region.
