The youngest period of the Mesozoic Era is the Cretaceous. This period spans from approximately 145 to 66 million years ago and is significant for the dominance of dinosaurs and a diverse range of marine life. The Cretaceous also includes important geological and biological events, such as the appearance of flowering plants and significant shifts in ecosystems. Understanding the Cretaceous is essential in paleontology and geology, as it leads up to the mass extinction event that marked the end of the dinosaurs, making it a pivotal time in Earth's history.
