The Ireviken Event, the Mulde Event, and the Lau Event. Wikipedia
Continuing from the Ordovician Period, Laurentia and Baltica continue to move together. The Caledonian orogeny (mountain formation) enters the beginning of its main phases (Scandian and Grampian) that formed mountains in Scandanavia, Scotland, and Ireland. The Grampian Phase, like the Taconic orogeny, was caused by an island arc colliding with Laurentia.
Baltica and the Avalonia terrane continue to collide and suture.
As the world warms, sea levels rise and flood continents.
The first land plants appear.
Baltica begins full collision with the Laurentia land mass. The remainder of the Iapetus Ocean continues to narrow as Avalonia moves toward Laurentia.
A large peninsula, which included present day Australia and Antarctica, extends north from Gondwana.
Benambran orogeny, the Silurian phase of the Lachlan orogeny in Australia.
As sea levels fall again, three minor extinction events occur: the Ireviken Event, the Mulde Event, and the Lau Event.
Laurentia, Baltica and Avalonia begin to form the supercontinent of Euramerica, also known as Laurussia.
