The Bostobe Formation is a geological formation in Qaraghandy & Qyzylorda, Kazakhastan whose strata date back to the Late Cretaceous.
The Luohandong Formation is an Early Cretaceous geologic formation of the Ordos Basin in Inner Mongolia, China. The formation was initially dated to the earliest Cretaceous; Valanginian to Barremian, but later dating established an Aptian to Albian age. Dinosaur remains are among the fossils that have been recovered from the formation. Pterosaur fossils have also been recovered from the formation.
The Tsagaantsav Formation, Tsagantsab Formation or Tsagan-Tsab Formation is an Early Cretaceous geologic formation in Mongolia. Indeterminate sauropod and psittacosaurid remains have been recovered from the formation. Remains of the pterosaur Noripterus, which were originally given their own genus, "Phobetor" have also been recovered from the formation.
The Murtoi Formation is a geologic formation in vicinity of Lake Gusinoye in Russia. The Murtoi Fm's sedimentation age. It was deposited in the late Valanginian to Early Hauterivian of the Early Cretaceous.
The Sinuiju Formation(신의주층) is a geologic formation in North Korea. Formerly of uncertain age, it is now thought to be Early Cretaceous. A variety of fossils are known from the formation, including those of anurognathid pterosaurs and birds such as the specimen of a very large enantiornithine with a 5 cm (2.0 in) long tibia and a 3.5 cm (1.4 in) long pygostyle. Frogs have also been found in the formation. Numerous compression fossils of insects have also been found.
The Ialovachsk or Yalovach Formation is a geologic formation in Kyrgyzstan, Tajikistan and Uzbekistan dating to the Santonian age of the Cretaceous period.
The Jobu Formation is a Cretaceous geologic formation of Late Cenomanian age. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The oldest confirmed tyrannosaurid premaxillary tooth was recovered from the Jobu Formation. The mammal Sorlestes is also known from the formation.
The Karabastau Formation is a geological formation and lagerstätte in the Karatau Mountains of southern Kazakhstan whose strata date to the Middle to Late Jurassic. It is an important locality for insect fossils that has been studied since the early 20th century, alongside the rarer remains of vertebrates, including pterosaurs, salamanders, lizards and crocodiles.
The Alamyshik Formation is a geological formation in Kyrgyzstan whose strata date back to the Albian stage of the Early Cretaceous. Pterosaur remains are among the fossils that have been recovered from the formation.
The Apón Formation is a geological formation in northwestern Venezuela and northern Colombia, whose thick-bedded limestone interbedded with subordinate amounts of dark gray calcareous shale and sandy shale strata date back to the Early Cretaceous. Pterosaur remains of Ornithocheiridae indet. are among the fossils that have been recovered from the formation.
The Khilok Formation is an Early Cretaceous geologic formation in Buryatia, Russia. While the lower portion of the formation consists of sandstone and conglomerates, the upper portion of the formation largely consists of trachybasalt, these deposits have been dated to the Aptian. A thin 20 cm bed is known from the formation containing the remains of numerous indeterminate vertebrates, including dinosaur and pterosaurs and an indeterminate species of Kirgizemys.
The Lagarcito Formation is an Albian geologic formation in Argentina. Pterosaur fossils have been recovered from the formation. The formation overlies the La Cruz Formation and is overlain by the San Roque Formation. The sandstones and mudstones of the formation were deposited in a fluvial and mostly lacustrine environment. The fossil association and the geological evidence indicate that the Lagarcito Formation represents a perennial shallow lake situated in an alluvial plain where detrital sedimentation and semiarid climatic conditions predominated.
The Pudovkino Formation is a Late Cretaceous (Campanian) geologic formation in Saratov Oblast of European Russia. Pterosaur fossils have been recovered from the marine marls of the formation.
The Rybushka Formation is a Campanian geologic formation in the Penza and Saratov Oblasts of European Russia. Pterosaur, fish and invertebrate fossils have been recovered from the formation.
The Sekmenevsk Formation is a Cretaceous geologic formation in the Kursk Oblast of European Russia. Pterosaur fossils have been recovered from the formation.
The Zhirkindek Formation is a Late Cretaceous geologic formation in Kazakhstan. The primary lithology is sand with interbeds of clay and silt, and represents a coastal to coastal marine environment. The formation has produced numerous fossils, including Lindholmemydid and Trionychid cryptodires, indeterminate remains of dinosaurs and an indeterminate species of pterosaur Azhdarcho.
The Alachua Formation is a Miocene geologic formation in Florida. The claystones, sandstones and phosphorites of the formation preserve many fossils of mammals, birds, reptiles and fish, among others megalodon.
The Marne de Flize is a geologic formation in France. It preserves fossils dating back to the Toarcian stage of the Jurassic period.
The Moskvoretskaya Formation is a Middle Jurassic geologic formation in the European part of Russia. It consists of continental claystones, siltstones and sandstones deposited in karstified segments of underlying Middle Carboniferous limestone, that would have formed underground aquifers.
The El Molino Formation is a Maastrichtian geologic formation pertaining to the Puca Group of central Bolivia. The formation comprises fine-grained sandstones and sandy limestones with stromatolites deposited in a shallow marine to lacustrine environment. The formation has provided fossils of Dolichochampsa minima, and ichnofossils of Ankylosauria indet., Ornithopoda indet., Theropoda indet. and Titanosauridae indet. The tracksite of Cal Orcko is the best known example of the ichnofossil locations of the formation. The ichnofossil of Ligabueichnum bolivianum may be attributed to an ankylosaur. The fossil fish species Dasyatis molinoensis is named after the formation.
