Ledringhem Paleozoic era. Euramerica, also known as Laurussia, was a minor supercontinent created in the Devonian as the result of a collision between the Laurentian, Baltica, and Avalonia cratons. Euramerica became a part of the major supercontinent Pangaea in the Permian. In the Jurassic, when Pangaea rifted into two continents, Gondwana and Laurasia, Euramerica was a part of Laurasia.

The Laurentian craton became a part of North America while Baltica became a part of Eurasia, and Avalonia was split between the two. Ledringhem lies on the London-Brabant Massif,
