Kungurian

The Kungurian period, which occurred approximately 237 to 227 million years ago, is a significant epoch in the geological timescale. It is part of the Permian period, which is the last period of the Paleozoic Era. The Kungurian stage is named after the city of Kungur in Russia, where the first evidence of this epoch was discovered. During this time, the Earth experienced significant changes in its environment and climate, leading to the evolution of various species, including the ancestors of modern reptiles.

One of the most notable features of the Kungurian period is the diversification of reptiles, which were evolving into the dominant land animals. Reptiles, such as early turtles, were present during this time, and their descendants would eventually give rise to birds and mammals. The Kungurian period also saw the appearance of the first synapsids, which are the ancestors of mammals. These early synapsids were carnivorous and had features that resemble both reptiles and mammals.

The climate during the Kungurian period was cooler than the preceding Carboniferous period, leading to a decrease in humidity and a shift towards drier conditions. This change in climate had a significant impact on the environment, causing the regression of shallow seas and the expansion of land areas. As a result, coastal swamps and forests were replaced by drier forests and grasslands, which provided new opportunities for the evolution of land
