The Ankarafantsika Formation is a Late Cretaceous (Cenomanian) geologic formation of the Mahajanga Basin in the Boeny region of Madagascar, Africa. The fine-grained sandstones of the formation were deposited in a fluvial to lacustrine environment.
The Arapahoe Formation is a geological formation of latest Cretaceous (Maastrichtian) age that is present within the Denver Basin that underlies the Denver, Colorado, area. The formation includes fossil leaves and dinosaur remains, although none of the latter have yet been referred to a specific genus. It also includes aquifers that are important sources of water for the area.
The Bahia Group, also known as Bahia Series, is an Aptian geologic group of the Recôncavo Basin in Bahia, Brazil. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The conglomerates were deposited in an estuarine environment.
The Billman Creek Formation is a Mesozoic geologic formation in south-central Montana. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Birdrong Sandstone is an Early Cretaceous geologic formation of the Barrow Group in Western Australia. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Chilgog Formation, also known as the Chilgok Formation, is an Early Cretaceous geologic formation in South Korea. Formerly dated to the Berriasian to Hauterivian, later dating has established an Albian age. Dinosaur remains, possibly of sauropods, are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Cokedale Formation is a Mesozoic geologic formation in the United States. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Coli Toro Member is a Campanian geologic member in Argentina. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The sandstones of the formation were deposited in a lacustrine environment.
The Forcall Formation is an Early Cretaceous (Aptian) geologic formation in Spain. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Futaba Group is a Late Cretaceous geologic group in Japan. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. It consists of both fluvial and shallow marine sediments. The plesiosaur Futabasaurus was found in this unit.
The Hidden Lake Formation is a Late Cretaceous geologic formation in Antarctica. The sandstones and siltstones of the formation were deposited in a deltaic environment.
The Kootenai Formation is a Lower Cretaceous geologic formation. The Kootenai was deposited in a foreland basin east of the Sevier thrust belt in western Montana. The lithology consists of a basal conglomerate with overlying non-marine sandstones, shales and lacustrine limestones.
The Lushangfen Formation is an Early Cretaceous aged geologic formation in China. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Molecap Greensand is a Late Cretaceous geologic formation, located in the state of Western Australia in Australia.
The Packard Formation is a Mesozoic geologic formation. The formation may be from the Kirtlandian land vertebrate age. It has a similar fauna to the Corral de Enmedio Formation.
The Tahora Formation is a Late Cretaceous geologic formation that outcrops in northeastern New Zealand near Napier. It is Haumurian in age according to the New Zealand geologic time scale. It forms part of the Upper Cretaceous to Teurian (Danian) Tinui Group. It unconformably overlies the Jurassic to Lower Cretaceous Urewera Group or the Upper Cretaceous Matawai Group. It is conformably overlain by the Haumurian to Teurian Whangai Formation. It consist of three members, the Maungataniwha Sandstone Member, the Mutuera Member and the Houpapa Member. It is named for Tahora Station, south of Matawai in the Gisborne Region. The aptly named Maungataniwha Sandstone Member is known for its rich reptile fossil remains, first investigated by amateur palaeontologist Joan Wiffen.
The Tres Hermanos Formation is a geologic formation in central and west-central New Mexico. It contains fossils characteristic of the Turonian Age of the late Cretaceous.
The Ankazomihaboka Formation is a Coniacian geologic formation in the Mahajanga Basin of northwestern Madagascar. The formation comprises claystones and sandstones deposited in a fluvial to lacustrine environment. The formation is overlain by the Marovoay Beds and overlies basalt.
The El Jume Formation is an Early Cretaceous geologic formation in Argentina. Indeterminate fossil dinosaur tracks have been reported from the formation. The formation, belonging to the El Gigante Group, overlies the Los Riscos Formation and is overlain by the El Toscal Formation. The sandstones and claystones of the formation were deposited in a fluvial environment. Part of the formation was assigned to a new formation, Balde de Leyes Formation in 2015.
The Khodzhakul Formation is a Cenomanian aged geologic formation in Uzbekistan. Dinosaur remains are among the fossils that have been recovered from the formation. As well as those of Mammals. It is part of the same stratigraphic succession as the overlying Bissekty Formation.
