Lower Pennsylvanian floras are represented in the Peñarroya–Belmez–Espiel (Córdoba) and Villanueva del Río y Minas (Sevilla) coalfields of SW Spain (also strike-slip controlled), at La Camocha, near Gijón (Asturias), and in other parts of northern Spain.Middle Pennsylvanian is represented near Oporto, but more completely in the Central Asturian Coalfield, as well as other, more limited localities in NW Spain and the Pyrenees.The Sauk Sequence extends throughout North America and appears to extend into Europe.The Tippecanoe Sequence also covers much of North America and may well extend into Europe and Africa.A general review is presented of the Carboniferous floral records in the Iberian Peninsula in the context of the geological history and distribution of the different basins.Mississippian floras are found in Sierra Morena, where major strike-slip faults brought in terranes of diverse provenance.Twentieth-century geologists taught the familiar maxim: "The present is the key to the past." But now that catastrophic processes are widely employed to describe the strata record, twenty-first century geologists are wondering whether "marine flood sedimentation is the key to the past." Geological strata and their contained marine fossils provide critical evidence that the ocean once covered the continents, even the highest continental areas.Extremely widespread strata blankets argue for an intercontinental or global flood.
Uppermost Pennsylvanian (Stephanian C–Autunian) floras are present in the strike-slip controlled Douro and Buçaco basins of North Portugal, the Pyrenees, Central Spain (Ciudad Real, Guadalajara, Zaragoza), and SW Spain (Guadalcanal and Valdeviar in Sevilla province).If you are unable to locate the citation for a data layer, please contact the Portal Manager.
