Baltica (Baltoscandia) The continental mass of north-western Europe (including most of what are now the UK, Scandinavia, European Russia, and Central Europe) that formed the south-eastern margin of the Iapetus Ocean. During the Caledonian orogenic event, this continental mass was brought into juxtaposition against N. America and Greenland by subduction of the Iapetus Ocean during the Silurian and Early Devonian.
