Baltica in 550 mya (green)

Baltica was a late-Proterozoic, early-Palaeozoic continent that now includes the East European craton of northwestern Eurasia. Baltica was created as an entity not earlier than 1.8 billion years ago[citation needed]. Before this time, the three segments/continents that now compose the East European craton were in different places on the globe. Baltica existed on a tectonic plate called the Baltic Plate.

History

  • ~1.8 billion years ago, Baltica was part of the major supercontinent Columbia.
  • ~1.5 billion years ago, Baltica along with Arctica and East Antarctica were part of the minor supercontinent Nena.
  • ~1.1 billion years ago, Baltica was part of the major supercontinent Rodinia.
  • ~750 million years ago, Baltica was part of the minor supercontinent Protolaurasia.
  • ~600 million years ago, Baltica was part of the major supercontinent Pannotia.
  • ~Cambrian, Baltica was an independent continent.
  • ~late Ordovician, Baltica collided with Avalonia (most of modern Western Europe)
  • ~Devonian, Baltica collided against Laurentia, forming the minor supercontinent Euramerica.
  • ~Permian, all major continents collided against each other to form the major supercontinent Pangaea.
  • ~Jurassic, Pangaea rifted into two minor supercontinents, Laurasia and Gondwana. Baltica was part of the minor supercontinent Laurasia.
  • ~Cretaceous, Baltica was part of the minor supercontinent Eurasia.
  • ~Present, Baltica is part of the forming minor supercontinent Afro-Eurasia.
