Cretaceous Period Overview
The Cretaceous Period, lasting from approximately 145 to 66 million years ago, is the final period of the Mesozoic Era. It is known for being the era when dinosaurs roamed the Earth, including iconic species like Tyrannosaurus rex, Triceratops, and Velociraptors. The Cretaceous Period is divided into the Early Cretaceous, Late Cretaceous, and the Cretaceous-Paleogene extinction event at the end.
Geological Changes
During the Cretaceous Period, the supercontinent Pangaea continued to break apart. This breakup led to the formation of separate landmasses that we recognize today. The climate was warmer and more stable than in previous periods, leading to higher sea levels and the development of shallow seas. Aquatic biodiversity flourished during this time.
Flora and Fauna
The Cretaceous Period saw a diverse array of plant and animal life. In addition to dinosaurs, mammals, birds, and marine reptiles thrived during this time. Flowering plants began to emerge, leading to the spread of new vegetation across the planet. In the oceans, marine reptiles like plesiosaurs and mosasaurs dominated the waters.
Cretaceous-Paleogene Extinction Event
The Cretaceous-Paleogene extinction event, also known as the K-Pg extinction event, occurred around 66 million years ago and marked the end of the Cretaceous Period. This event resulted in the mass extinction of around 75% of Earth's plant and animal species, including the non-avian dinosaurs. It is believed to have been caused by a combination of factors, including the impact of a massive asteroid and extensive volcanic activity.
Fossil records from the Cretaceous Period provide valuable insights into the biodiversity and evolution of life on Earth. The discoveries made in the Cretaceous rock formations have helped scientists piece together the history of our planet and understand the intricate relationships between different species.
Paleontologists continue to study the remnants of the Cretaceous Period to uncover new information about ancient life forms and the environmental conditions of the time. The legacy of this period lives on in the fossils that have been unearthed, shedding light on the incredible diversity of life that once existed on Earth.
