Silurian Period

The Silurian Period is a geologic period that lasted from about 443 to 419 million years ago. It is part of the Paleozoic Era and is named after the ancient Silures tribe of Wales.

Geology

During the Silurian Period, the Earth experienced significant changes. One of the most notable events was the continuation of the Ordovician-Silurian extinction event, which led to the disappearance of many marine species.

Climate

The climate during the Silurian Period was relatively stable and warm, with no polar ice caps. This resulted in a more uniform distribution of heat around the planet.

Life Forms

The Silurian Period marked the diversification of marine life, with the appearance of many new species of fish, corals, and brachiopods. The first plants also began to colonize the land, and the first terrestrial arthropods appeared.
