The Molecap Greensand is a Late Cretaceous geologic formation, located in the state of Western Australia in Australia.
A proximal pedal phalanx from an indeterminate theropod has been recovered from the formation, [1] [2] alongside a jaw fragment of a pterosaur, [3] possibly an ornithocheirid. [4] Fossils of a mosasaur, cf. Platecarpus sp. were also reported from the formation. [5]
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species.
The Tuchengzi Formation is a geological formation in China whose strata span the Tithonian to Berriasian ages. Dinosaur fossils, particularly footprints, have been found from the formation.
The Toolebuc Formation is a geological formation that extends from Queensland across South Australia and the Northern Territory in Australia, whose strata date back to the Albian stage of the Early Cretaceous. Dinosaurs, pterosaurs, plesiosaurs, ichthyosaurs, protostegid turtles, sharks, chimaeroids and bony fish remains are among the fossils that have been recovered from the formation.
The Griman Creek Formation is a geological formation in northern New South Wales and southern Queensland, Australia whose strata date back to the Albian-Cenomanian stages of the mid-Cretaceous. It is most notable being a major source of opal, found near the town of Lightning Ridge, New South Wales. Alongside the opal opalised fossils are also found, including those of dinosaurs and primitive monotremes.
The Eumeralla Formation is a geological formation in Victoria, Australia whose strata date back to the Early Cretaceous. It is Aptian to Albian in age. Dinosaur remains are among the fossils that have been recovered from the formation, particularly from the Dinosaur Cove locality.
The Aguja Formation is a geological formation in North America, exposed in Texas, United States and Chihuahua and Coahuila in Mexico, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. Fossil palms have also been unearthed here.
The Broadford Beds Formation is a Sinemurian geologic formation in western Scotland. An indeterminate partial tibia of a theropod dinosaur are among the fossils that have been recovered from the formation
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 Intertrappean Beds are a Late Cretaceous and Early Paleocene geologic formation in India. The beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. The formation spans the Cretaceous–Paleogene boundary, with a stratigraphic range of only a few hundred thousand years before and after the boundary, and a significant debate exists about whether specific sites belong to the Cretaceous or the Paleocene.
The Miria Formation is a Late Cretaceous geologic formation, in Western Australia.
The Oum ed Diab Member is a middle-upper Albian geologic member, part of the Ain el Guettar Formation of Tunisia. Dinosaur remains are among the fossils that have been recovered from the formation.
The Pab Formation is a Late Cretaceous geologic formation in Balochistan, in western Pakistan. It is dominated by sandstone, with minor mudstone and shale components. Dinosaur remains are among the fossils that have been recovered from the formation.
The Early Cretaceous Phu Kradung Formation is the lowest member of the Mesozoic Khorat Group which outcrops on the Khorat Plateau in Isan, Thailand. This geological formation consists of micaceous, brown to reddish-brown siltstone beds with minor brown and grey shale and sandstone beds. Occasional lime-noduled conglomerate occurs.
The Qigu Formation is a Late Jurassic (Oxfordian) geologic formation in the Southern Junggar Basin in China. Indeterminate Dinosaur remains are among the fossils that have been recovered from the formation, including theropod teeth and a fibula. a stegosaur dorsal vertebra and a Eusauropod tooth. Xinjiangtitan was erroneously thought to be from this formation, but it is actually from the older Qiketai Formation, which is in a different basin. The term "Qigu Formation" is also used to sediments of equivalent age in the Turpan Basin, but this might better be treated as a separate formation. It is laterally equivalent to the Shishugou Formation.
The Shendi Formation is a Late Cretaceous geologic formation of the Atbara-Shendi Basin in northern Sudan. Indeterminate theropod remains have been recovered from it. As well as those of the dyrosaurid Hyposaurus. It consists of a lower unit of fine grained meandering channel sediments, separated by an erosive contact with overlying meandering to braided river channel sandstones.
The Sierra Perenchiza Formation is a late Campanian to late Maastrichtian geologic formation in Spain. Dinosaur, pterosaur, turtle, lissamphibian, frog and albanerpetontid remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus and the crocodylomorphs Acynodon, Doratodon ibericus and Musturzabalsuchus are also known from this 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 Lianmuqin Formation, also transcribed as Lianmugin Formation, and Lianmuxin Formation, is an Early Cretaceous geologic formation composed of "interbedded red green and yellow variegated mudstones and siltstones". Dinosaur remains have been recovered from it.
Ferrodraco is an extinct genus of anhanguerid pterosaur known from the Late Cretaceous Winton Formation of Queensland, Australia, containing the single species F. lentoni. The species was named after the former mayor of Winton, Graham Thomas ‘Butch’ Lenton. It is the most complete pterosaur fossil from Australia, being known from the holotype specimen AODF 876, consisting primarily of the anterior portion of the skull and dentary, cervical vertebral centra and a partial wing. Its wingspan was estimated to be about 4 meters (13 ft). Ferrodraco was found to have been within the subfamily Ornithocheirinae, as sister taxon to Mythunga. A recent study also recovered Ferrodraco as sister taxon to Mythunga, but both placed within the family Anhangueridae, more specifically within the subfamily Tropeognathinae. Ferrodraco is also the latest surviving member of Anhangueria.
The Shengjinkou Formation is an Early Cretaceous (Aptian)-aged Konservat-Lagerstätte composed of "interbedded red green and yellow variegated mudstones and siltstones" that is part of the larger Tugulu Group of China. Dinosaur and pterosaur remains have been recovered from the formation.
