Understanding the Post-Jurassic Period: A Geological Overview

Post-Jurassic refers to the geological period that followed the Jurassic Period, which spanned from approximately 200 million to 145 million years ago. The next geological period after the Jurassic was the Cretaceous Period, which began around 145 million years ago and ended with the mass extinction event that wiped out the dinosaurs about 65 million years ago.

The Post-Jurassic is characterized by the continued breakup of the supercontinent Pangaea, the formation of new ocean basins, and the evolution of new species of plants and animals. During this period, the climate cooled, and the Earth experienced a series of ice ages. The Post-Jurassic also saw the emergence of early mammals, birds, and other groups of organisms that would go on to play important roles in the Earth's ecosystems.

It is worth noting that the term "Post-Jurassic" is not a formally recognized geological period, but rather a general term used to describe the time after the Jurassic Period. The formal geological periods that followed the Jurassic are the Cretaceous, Paleogene, and Neogene Periods.
