  Abu Agag Formation (Egypt) | |
The Abu Agag Formation is a Turonian geologic formation in Egypt and Sudan. Indeterminate fossil ornithischian tracks have been reported from the formation. [1]
The formation comprises intercalated sandstones and highly bioturbated sand- and siltstone layers which are horizontal and wavy bedded. Horizontally laminated and thin bedded fine-grained sandstones as well as flaser- and ripple cross-lamination characterize a low-energy environment within this fluvial succession.
The following fossils have been reported from the formation: [2] [3]
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 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 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 Guichón Formation is a Late Cretaceous geologic formation of the Paysandú Group in Uruguay. Dinosaur remains are among the fossils that have been recovered from the formation.
The In Beceten Formation, also Beceten or Ibecten is a Coniacian to Santonian geologic formation in the Iullemmeden Basin of Niger. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The lithology primarily consists of clays, fine limestones and sandy clays.
The Lupata Group is an Aptian geologic group in the Tete Province of Mozambique and the Northern Region of Malawi. The group contains the Dinosaur Beds, a fossiliferous unit in Malawi that has provided dinosaur remains. eubidono assistente redigido gaseificada lexosh vasos paciência caeuv 519 - 603 < / r e f> pp laeibu catódicos caleidoscopio existe vaeknkri casino brindado
The Moenave Formation is a Mesozoic geologic formation, in the Glen Canyon Group. It is found in Utah and Arizona.
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 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 Broome Sandstone, formerly known as the Broome Beds, is an Early Cretaceous geologic formation found in Western Australia, and formerly considered part of Dampier Group. Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species Garbina roeorum have been reported from the formation since the 1990s.
The Plainview Formation is an Early Cretaceous (Albian) geologic formation of the Dakota Group in Colorado. Fossil ankylosaur tracks and tracks of Caririchnium sp. have been reported from the formation.
The Ansbachersandstein is a Late Triassic (Carnian) geologic formation in Germany. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Kiyosu-e Formation is a Middle Jurassic (Callovian) to Early Cretaceous (Berriasian) geologic formation of the Toyonishi Group in Yamaguchi Prefecture, Japan. Fossil ornithopod tracks have been reported from the formation.
The Festningen Sandstone is an Early Cretaceous (Barremian) geologic formation in Svalbard, in the far north of Norway. Fossil ornithopod tracks have been reported from the formation.
The Baños del Flaco Formation is a Late Jurassic to Early Cretaceous (Tithonian to Berriasian geologic formation in central Chile. The formation comprises limestones and sandstones deposited in a shallow marine to fluvial environment. Fossil ornithopod tracks have been reported from the formation.
The Irhazer Shale or Irhazer II Formation is a Middle Jurassic geologic formation of the Irhazer Group in the Agadez Region of Niger. Fossil ornithopod tracks have been reported from the formation. The dinosaur Spinophorosaurus is known from the formation.
The Akaiwa Formation is an Early Cretaceous (Hauterivian-Barremian) geologic formation in central Honshu, Japan. Indeterminate ornithischian fossils are known from the formation. Fossil ornithopod tracks have been reported from the formation. As well as the turtle Kappachelys
The Bull Run Formation is a Late Triassic (Norian) stratigraphic unit in the eastern United States. Fossil fish bones and scales have been found in outcrops of the formation's Groveton Member in Manassas National Battlefield Park. Indeterminate fossil ornithischian tracks have been reported from the formation.
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 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.
