Silurian Information

The Silurian Period (443–419 million years ago) was a time of climate stabilization following the end-Ordovician mass extinction. The climate became warmer, and sea levels rose, leading to the expansion of shallow marine ecosystems. Coral reefs flourished, and new marine predators like Eurypterids (sea scorpions) and early jawed fish emerged. One of the most significant events was the colonization of land—early vascular plants such as Cooksonia appeared, along with the first arthropods to venture onto land. These evolutionary advances set the stage for the more complex terrestrial ecosystems that developed in the Devonian.
