Kimmeridgian

The Kimmeridgian is a geological period that occurred approximately 157 to 152 million years ago, during the Late Jurassic era. It is named after Kimmeridge, a village in England, where rocks from this period were first studied. This time is known for significant marine life and the formation of important sedimentary rocks. Fossils from the Kimmeridgian include various dinosaurs and marine creatures like ammonites. Understanding this period helps geologists and paleontologists trace Earth's history, the evolution of life, and how ancient environments changed over time.
