The Silurian was from 443 to 419 million years ago. On land, moss forests spread along rivers. The first vascular plants evolved, represented by Cooksonia in the northern hemisphere and Baragwanathia in Australia. Land animals included arachnoid and millipedes.
In the ocean, the first bony fish, including Acanthodians, and the first jawed fish appeared. There were also many sea scorpions, some up to several meters long. Theree were also leeches, Brachiopods, mollusks, trilobite, and many other invertebrates.
Plants and animals finally emerged out of water onto land in this time period.

In the Silurian Period, roughly 420-440 million years ago.
In the paleozoic, more specifically the Silurian period. Liverworts had evolved by 472 million years ago, putting the very earliest land plants closer to the end of the Ordovician than at the beginning of the Silurian.

The Silurian period resembles the Ordovician period in terms of marine life, but is marked by the appearance of land dwelling plants and animals during the latter part of the period. Animals that lived on land during Silurian time include spiders, millipedes, and scorpions.A significant amount of ocean water evaporated over North America during this period. The salt deposits in Syracuse, New York and Detroit, Michigan are remnants of this evaporation.

The Silurian period occurred from 443 million years ago until 416 million years ago. It saw the emergence of animals such as coral and fish that began quickly populating the oceans, and plants like the fern first appeared on the planet.
