Cretaceous Period: An Overview
The Cretaceous period, spanning from approximately 145 to 66 million years ago, was the last period of the Mesozoic Era. It is best known for being the time when dinosaurs roamed the Earth, including iconic species like Tyrannosaurus rex and Triceratops. The Cretaceous period is divided into two subdivisions: the Early Cretaceous and the Late Cretaceous.
Geological Events
During the Cretaceous period, the supercontinent Pangaea continued to break apart, leading to the eventual formation of the modern continents. The breakup of Pangaea had significant implications for climate, ocean circulation, and the distribution of plant and animal species.Climate and Environment
The climate during the Cretaceous period was generally warm and tropical, with high sea levels and lush vegetation covering much of the Earth. The presence of shallow seas in many parts of the world allowed for diverse marine ecosystems to thrive. Dinosaurs dominated the terrestrial environment, while marine reptiles like plesiosaurs and mosasaurs ruled the oceans.Cretaceous Extinction Event
The Cretaceous period ended with one of the most well-known extinction events in Earth's history, known as the Cretaceous-Paleogene (K-Pg) extinction event. This event, which occurred approximately 66 million years ago, resulted in the mass extinction of numerous plant and animal species, including the non-avian dinosaurs. The cause of the K-Pg extinction event is still debated, with theories ranging from asteroid impacts to massive volcanic eruptions.Legacy of the Cretaceous Period
Despite the catastrophic events that marked the end of the Cretaceous period, life on Earth persisted and eventually gave rise to new forms of plant and animal diversity. The legacy of the Cretaceous period can be seen in the modern flora and fauna that inhabit our planet today, as well as in the rich fossil record that provides valuable insights into the history of life on Earth.
