The Silurian Period
The Silurian period is a geological period that lasted from approximately 443 to 419 million years ago. It is named after the ancient Celtic tribe of the Silures. The Silurian period is known for significant evolutionary events and the diversification of marine life.
Geology of the Silurian Period
During the Silurian period, the Earth's continents were clustered together in a supercontinent called Gondwana. The climate was generally warm and relatively stable, leading to the development of extensive shallow seas.
Biological Evolution
The Silurian period saw the continued evolution of marine life, including the rise of jawed fish and the diversification of early land plants. The period is also known for the appearance of the first vascular plants, which paved the way for the colonization of land by plants and arthropods.
