Cretaceous Period
The Cretaceous Period, which lasted from 145 to 66 million years ago, is one of the three divisions of the Mesozoic Era. It characterized by the end of the dinosaurs and the emergence of various flowering plant species. During this time, the environment was warm and humid due to a period of intense volcanic activity, resulting in the formation of shallow seas, which caused the separation of landmasses and the dramatic transformation of the landscape. This period is of great significance to scientists, as it marks a major evolutionary transition in life on Earth and the first appearance of modern bird species. Its fossil record has provided us with valuable insights into the diversity and evolution of life during this period. The Cretaceous Period is also significant for its seafloor deposits, which form important sources of oil and gas found in today’s energy reserves.
