PENNSYLVANIAN PERIOD Meaning and
Definition
-
The Pennsylvanian Period, also known as the Late Carboniferous Period, was a geological time period that occurred approximately 323 to 298 million years ago. It represents the later part of the Carboniferous Period and is characterized by significant geological and biological changes.
Geologically, the Pennsylvanian Period was marked by extensive mountain building and the formation of vast lowland areas, such as coastal plains and swamps. These lowland environments were characterized by abundant plant growth, especially ferns, club mosses, and early seed plants. The lush vegetation in these swamps led to the development of extensive coal deposits, which are a significant economic resource today.
The Pennsylvanian Period also witnessed the diversification and dominance of amphibians and reptiles. Many different types of insects, including dragonflies and primitive cockroaches, also flourished during this time. Marine life evolved significantly during this period, with the appearance of new groups of fish, including sharks and rays, as well as corals and mollusks.
The Pennsylvanian Period played a crucial role in shaping the Earth's geological and biological history. Its coal deposits are important sources of fossil fuels today, and the diverse plant and animal life provided the foundation for future evolutionary developments.

Etymology of PENNSYLVANIAN PERIOD
The term "Pennsylvanian Period" is derived from the name of the state of Pennsylvania in the United States. The Pennsylvanian Period is a division of geological time, also known as the Upper Carboniferous Period, which occurred from approximately 323.2 million to 298.9 million years ago. Pennsylvania is renowned for its vast coal deposits that were formed during this period, hence the association between the state and the geological era. The term "Pennsylvanian" was first introduced in the late 19th century by American geologists, who used names of prominent geographical locations to help classify different time periods in Earth's history.
