A synthesis of the upper Moscovian sedimentological and palaeontological record of terrestrial habitats across the Variscan foreland suggests a contraction and westward shift of the coal swamps. These changes can be correlated with pulses of tectonic activity resulting from the northwards migration of the Variscan Front. This tectonic activity caused drainage patterns where the coal swamps were growing and replacement of swampy arborescent lycopsids by vegetation dominated by marattialean ferns. Reductions in rainfall further affected the swamp vegetation. In Asturian times, the swamps in Variscan Euramerica became replaced by predominantly conifer and cordaite vegetation that favoured much drier substrates. The last development of coal swamps in Variscan foreland was of early Cantabrian age. In the USA, lycopsid-dominated coal swamps persisted for a little longer and disappeared by middle-late Cantabrian times.
