Silurian Period

The Silurian period is a geological period that extends from about 443 to 419 million years ago. It is part of the Paleozoic era and is named after the Silures, a Celtic tribe in Wales.

Geological Events

During the Silurian period, the Earth's climate was relatively warm, and there were significant changes in the Earth's surface due to tectonic activity. The period is known for the widespread diversification of marine life, including the appearance of the first jawed fish and the proliferation of coral reefs.

Key Concepts

• Climate: The Silurian period featured a warm climate, with no polar ice caps.
• Continental Drift: The movement of continents continued during the Silurian period, leading to the formation of new landmasses and ocean basins.
• Biodiversity: The Silurian saw the diversification of marine life, including the first jawed fish and the expansion of coral reefs.
• Geological Formations: The period saw the development of sedimentary rocks, including limestone and shale, as well as the formation of volcanic islands and mountain ranges.

Study Guide
