Batrachiderpeton is an extinct genus of nectridean tetrapodomorphs within the family Diplocaulidae; it was a basal member of the family. The type species is B. reticulatum and was found in a coal field in Northumberland, England at a locality that also yields the remains of Anthracosaurus russelli. A second species is also known: B. lineatum.
Strepheoschema is an extinct genus of prehistoric bony fish that lived during the early Mississippian (Tournaisian–Visean) in what is now Berwickshire, Scotland, and Northumberland, England. Fossils were recovered from the Ballagan Formation.
The Clifton Down Limestone is a geologic formation in England. It preserves fossils dating back to the Carboniferous period.
The Bee Low Limestones is a geologic formation in England. It preserves fossils dating back to the Carboniferous period.
The Spilsby Sandstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Durlston Formation is a geologic formation in England. Particularly in the Isle of Purbeck. It preserves fossils dating back to the Berriasian stage of the Lower Cretaceous.
The Claxby Ironstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Carstone Formation is a geological formation in England. It preserves fossils dating back to the Albian stage of the Cretaceous period. It predominantly consists of "greenish-brown, thick-bedded, cross-bedded, oolitic ferruginous sandstone".
The Stanford Formation is a geologic formation in England. It preserves fossils dating back to the Oxfordian stage of the Middle Jurassic period, around 160 million years ago.
The Fullers Earth Formation is a geological formation that outcrops in southern England. It is also mostly present in the subsurface of the Wessex Basin and offshore in the English Channel Basin, Celtic Sea Basin and St George's Channel Basin. It preserves fossils dating back to the Bathonian stage of the Middle Jurassic series such as the pterosaur Dolicorhamphus. It is the lateral equivalent of the Rutland Formation, Sharp's Hill Formation, Calcaire d’Ecouché, and Calcaire de Caen
The Llanfallteg Formation is a geologic formation in Wales. It preserves fossils dating back to the Ordovician period. It predominantly consists of ash containing siltstones, as wells as ash fall deposits and tuffs. It likely dates to the Darriwilian based on graptolites. The local graptolite fauna includes Didymograptus artus and Glossograptus armatus. The local trilobite fauna includes agnostids, phacopids and asaphids.
The Wittering Formation is a geologic formation in England. It preserves fossils dating back to the Paleogene period.
The Headon Hill Formation is a geological formation found in the Isle of Wight and south Hampshire, England. It preserves fossils dating back to the Priabonian stage.
The Woolwich Formation is a geological formation in southeast England. It preserves fossils dating back to the Paleogene period.
The Whitcliffe Formation is a geologic formation in England. It preserves fossils dating back to the Silurian period.
The Weybourne Crag Formation is a geologic formation in England. It preserves fossils.
The Ancholme Group is a geologic group in England. It preserves fossils dating back to the Jurassic period. It has previously been referred to as the Ancholme Clay Group. The group consists of predominantly grey, marine mudstone and silty mudstone with beds of argillaceous limestone nodules. In parts of its range it interfingers with the Corallian Group, which predominantly consists of coralliferous limestones.
The Solent Group is a geological group in the Hampshire Basin of southern England. It preserves fossils ranging in age from Priabonian to Rupelian. The group is subdivided into three formations, the Headon Hill Formation, the Bembridge Limestone Formation and the Bouldnor Formation.
The Selborne Group is a geologic group in England. It preserves fossils dating back to the Cretaceous period. It comprises the Gault Formation and the overlying Upper Greensand Formation.
