The exact date of the earliest sea life is currently unknown, but life was well established by the Ordovician, which started 488 million years ago. Trilobites, corals and brachiopods and privative fish were common.
During the Ordovician period, there was a rapid diversification of marine life, with the development of complex ecosystems and the proliferation of different species. The climax of the Ordovician period was marked by a significant increase in biodiversity, including the emergence of new groups of organisms such as jawed fish and terrestrial plants. This heightened diversity laid the groundwork for the subsequent evolutionary radiations seen in the following periods.

Ordovician Period
The Ordovician lasted for 47 million years from 490 to 443 Million Years Ago.
Algae was the dominant plant of the Ordovician. There were little to no other plants (other then algae) during the Ordovician. In the Ordovician, the common types of algae were Stromatolites (Blue green algae), and Tetradium (Red algae).
