The Spilsby Sandstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
Bouliachelys is an extinct genus of sea turtle from Cretaceous Australia. Its parent taxon is the clade Dermochelyoidae.
Amiopsis is an extinct genus of prehistoric bony fish belonging to the family Amiidae. Fossils are known from the Late Jurassic Solnhofen Limestone, Germany, the Early Cretaceous Purbeck Group, England, La Pedrera de Rúbies Formation, Spain and Bernnissant Iguanodon locality, Belgium and the Late Cretaceous (Cenomanian) of the Balkans. The monophyly of the genus is questionable, due to it being based on a single character, "the presence of three or more lateral fossae on each side of most abdominal centra". Remains previously assigned to this genus from the Early Cretaceous Las Hoyas, Spain have been moved into the new genus Hispanamia.
Oweniasuchus is an extinct genus of goniopholidid mesoeucrocodylian. Remains have been found from England and Portugal that are Cretaceous in age.
Vectisuchus is a genus of goniopholidid mesoeucrocodylian, known from the Early Cretaceous-age Wealden Group of the Isle of Wight, England. It was a small, piscivorous crocodylomorph with a narrow, elongate snout, and relatively long forearms. The type specimen, SMNS 50984, was found in 1977. When discovered, it was complete and right-side-up, but the posterior portion was lost during excavation. Vectisuchus was described in 1980. The type species is V. leptognathus.
The Tuscaloosa Formation is a geologic formation in Alabama. It preserves fossils dating back to the Cretaceous period.
The Coleraine Formation is a geologic formation in Minnesota. It preserves fossils dating back to the Cretaceous period.
The Benton Shale is a geologic formation in Montana, Wyoming, North Dakota, South Dakota, Colorado, Kansas, and Nebraska. It preserves fossils dating to the Cretaceous Period. The term Benton Limestone has also been used to refer to the chalky portions of the strata, especially the upper beds of the strata presently classified as Greenhorn Limestone. The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.
The Sandringham Sandstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Skegness Clay is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Abbott's Cliff Formation is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Ferruginous Sands is a geologic formation in England. It preserves fossils dating back to the Aptian Stage of the Cretaceous period. It consists of "a number of heavily bioturbated coarsening-upward units each comprising dark grey sandy muds or muddy sands passing up into fine-to medium-grained grey to green glauconitic sands." The dinosaur Vectaerovenator inopinatus is known from the formation. Shark teeth are also known from the formation, including those of an indeterminate lamniform shark and Palaeospinax.
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 Eggardon Grit is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Claxby Ironstone is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Burwell Rock Formation is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Carstone Formation is a geologic 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 Blackdown Greensand is a geologic formation in England. It preserves fossils dating back to the Cretaceous period.
The Cromer Knoll Group is a geologic group found at outcrops in England and developed extensively beneath the North Sea. It preserves fossils dating back to the Early Cretaceous period.
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.
Anatolemys is an extinct turtle genus in the family Macrobaenidae. Two species are known, both of which lived in the Late Cretaceous. Fossils were discovered in the Yalovach Formation of Tajikistan, the Kulbikin Member and Khodzhakul and Bissekty Formations of Uzbekistan and the Bostobe Formation of Kazakhstan.
