The Manassas Sandstone is a Carnian Stage sandstone geological formation in Virginia, United States.
The Carnian Stage is part of the Triassic System of the Mesozoic.
Fossil theropod tracks have been reported from the formation. [1]
The Bushveld Sandstone is a geological formation dating to roughly between 201 and 189 million years ago and covering the Carnian to Norian stages. The Bushveld Sandstone is found in Transvaal, South Africa, and is a member of the Stormberg Group. As its name suggests, it consists mainly of sandstone. Fossils of the prosauropod dinosaur Massospondylus have been recovered from the Bushveld Sandstone.
The Argana Group is a Permian to Triassic geological group in the western High Atlas northeast of Agadir, Morocco. Sometimes known as the Argana Formation, it contains eight geological members often divided into three formations. They include the Late Permian Ikakern Formation, the Early Triassic to Carnian Timezgadiouine Formation (T3-T5), and the Late Triassic Bigoudine Formation (T6-T8). Ornithischian tracks are geographically located in Marrakesh province. Indeterminate theropod remains and tracks are geographically located in Marrakesh province.
The Colalura Sandstone is a Middle Jurassic geologic formation of the Perth Basin of Western Australia. The formation overlies the Moonyoonooka Sandstone.
The Vega Formation is a Late Jurassic (Kimmeridgian) geologic formation of the Ribadesella Group in Asturias, Spain. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation is around 150 metres thick and consists of "alternating white, pale grey and reddish sandstones, and red mudstones with several sporadic conglomeratic beds typically arranged in minor finnig-upward cycles within a major cycle of the same character". An isolated caudal theropod vertebra and a partial tooth are known from the formation, belonging to large megalosaurids around 10 metres in length, comparable to Torvosaurus. Other remains known from the formation include fragmentary turtle remains, crocodylomorph teeth, as well as a sauropod caudal vertebra (MUJA-0650). Dinosaur tracks are also known from the formation, including large theropod footprints and poorly preserved quadrupedal dinosaur footprints.
The Chacarilla Formation is an Oxfordian to Early Cretaceous geologic formation of the Tarapacá Basin in northern Chile, close to the border with Bolivia. The marine and fluvial formation preserves several dinosaur trackways and has been declared a Natural Sanctuary in 2004.
Main Dolomite is a lithostratigraphic unit in the Alps of Europe. Formation was defined by K.W. Gümbel in 1857.
The East Berlin Formation is an Early Jurassic geological formation in New England, United States. Dinosaur footprints and trackways are abundant in this formation. These tracks include Eubrontes, Anchisauripus, and Anomoepus. Several museums, parks, and tourist attractions are based around the East Berlin Formation's dinosaur tracks, including Dinosaur State Park in Rocky Hill, Connecticut and Powder Hill Dinosaur Park in Middlefield, Connecticut.
The Ansbachersandstein is a Late Triassic (Carnian) geologic formation in Germany. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Iouaridène Formation is a Mesozoic geologic formation in Morocco. Fossil sauropod and theropod tracks have been reported from the formation. It is part of the 'Red Beds' of Morocco alongside the Guettioua Sandstone and Jbel Sidal Formation. The lithology consists of cyclic alternation of meter scale red mudstones and 10's of cm scale carbonate cemented mudstones to very fine sandstones.
The Tongfosi Formation is a Late Cretaceous (Cenomanian) geologic formation of the Yanji Group in China. Fossil ornithopod tracks of iguanodontids and theropods have been reported from the fluvial sandstones of the formation.
The Lower Maleri Formation is a sedimentary rock formation found in Andhra Pradesh and Telangana, India. It is the lowermost member of the Pranhita–Godavari Basin. It is of late Carnian to early Norian age, and is notable for its fossils of early dinosaurs, including the basal saurischian Alwalkeria.
The Areado Group is a Late Jurassic to Early Cretaceous geologic group in southeastern Brazil. The group was defined by Cardoso in 1968.
The Blasensandstein is a Carnian geologic member in Bavaria, Germany. It is part of the Hassberge Formation. Fossil theropod tracks have been reported from the formation.
The Zhiluo Formation is a geological formation in China, it is also alternatively considered a geological group under the name Zhiluo Group. It dates to the Middle Jurassic. It consists of sandstone, mudstone and siltstone of varying colours. It has received scientific attention for its uranium ore bodies present in the lower part of the formation. Fossil theropod tracks have been reported from the formation. These were described from two footprints found in Jiaoping Coal Mine by C. C. Young in 1966 as Shensipus tungchuanensis. These were in 2015 suggested to belong to Anomoepus. The dinosaur Lingwulong has been suggested to have come from the strata of this formation, previously having been attributed to the underlying Yanan Formation.
The Donghe Group is a Lower Cretaceous geologic formation in China. Fossil theropod tracks have been reported from the formation. It predominantly consists of conglomerate, alongside sandstone, siltstone and shale.
The Etjo Sandstone is an Early Jurassic geologic formation in northern Namibia. The formation overlies the Omingonde Formation in the Waterberg Basin and the Doros and Gai-As Formations in the Huab Basin and has a total thickness of 140 metres (460 ft). Fossil theropod tracks of Prosauropoda indet., Theropoda indet., Tetrapodium elmenhorsti, Saurichnium anserinum, S. damarense, S. parallelum and S. tetractis have been reported from the formation, deposited in an aeolian environment.
The Nugget Sandstone is a Late Triassic to Early Jurassic geologic formation that outcrops in Colorado, Idaho, Wyoming, and Utah, western United States.
The Redonda Formation is a geologic formation exposed in eastern New Mexico. It contains vertebrate fossils of the late Triassic Period. Fossil theropod tracks have been reported from the formation.
The Takutu Formation is a Late Jurassic geologic formation in Guyana and northern Brazil. The formation comprises sandstones deposited in a shallow water to littoral setting. Fossil theropod tracks have been reported from the formation. A paleobotanic analysis of drill cores of the formation was conducted by Thomas van der Hammen in 1966 and showed fossil Classiopolis flora.
The Benkersandstein is a geologic formation in Germany. It preserves fossils dating back to the Late Triassic (Carnian) period. Fossil theropod tracks have been reported from the formation.
