The Kuangyuan Series is a Late Jurassic (Oxfordian-?Tithonian) geologic formation in Sichuan (Szechuan), China. Dinosaur remains are among the fossils that have been recovered from the formation. [1]
The Oxford Clay is a Jurassic marine sedimentary rock formation underlying much of southeast England, from as far west as Dorset and as far north as Yorkshire. The Oxford Clay Formation dates to the Jurassic, specifically, the Callovian and Oxfordian ages, and comprises two main facies. The lower facies comprises the Peterborough Member, a fossiliferous organic-rich mudstone. This facies and its rocks are commonly known as lower Oxford Clay. The upper facies comprises the middle Oxford Clay, the Stewartby Member, and the upper Oxford Clay, the Weymouth Member. The upper facies is a fossil poor assemblage of calcareous mudstones.
Szechuanosaurus is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian. Its type species is based on several undiagnostic teeth from the Kuangyuan Series. Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation, also located in China.
The Lameta Formation, also known as the Infratrappean Beds, is a sedimentary geological formation found in Madhya Pradesh, Gujarat, Maharashtra, Telangana, and Andhra Pradesh, India, associated with the Deccan Traps. It is of the Maastrichtian age, and is notable for its dinosaur fossils.
The Arundel Formation, also known as the Arundel Clay, is a clay-rich sedimentary rock formation, within the Potomac Group, found in Maryland of the United States of America. It dates to the Early Cretaceous, and is of late Aptian or early Albian age. This rock unit had been economically important as a source of iron ore, but is now more notable for its dinosaur fossils. It is named for Anne Arundel County, Maryland.
The Río Colorado Subgroup, formerly named as Río Colorado Formation, is a Late Cretaceous geologic subgroup of the Neuquén Basin in northern Patagonia, Argentina. It belongs to the Neuquén Group and contains the Anacleto and Bajo de la Carpa Formations. The subgroup overlies the Río Neuquén Subgroup and is overlain by the Allen Formation of the Malargüe Group, separated by an unconformity dated to 79 Ma. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Claggett Shale is a geological formation in Montana whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
La Bocana Roja Formation is a geological formation in Baja California, Mexico whose strata date back to the Late Cretaceous, although the precise age is unclear. Dinosaur remains are among the fossils that have been recovered from the formation.
The Glauconie argileuse is a geological formation in Europe whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Minhe Formation is a geological formation in northwestern China, whose strata date back to the Late Cretaceous period.
The Huiquanpu Formation is a geological formation in Shanxi and Hebei provinces, China, whose strata date back to the Late Cretaceous period. It predominantly consists of purple-red mudstone, with subordinate grey-white sandy conglomerates.
The Yuliangze Formation, or Yuliangzi Formation, is a geological formation in Heilongjiang, China whose strata date back to the early-middle Maastrichtian. Dinosaur remains are among the fossils that have been recovered from the formation.
The Bissekty Formation is a geologic formation and Lagerstätte which crops out in the Kyzyl Kum desert of Uzbekistan, and dates to the Late Cretaceous Period. Laid down in the mid to late Turonian, it is dated to about 92 to 90 Ma.
The Ampthill Clay is a Mesozoic geologic formation in southern England. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Cardiel Formation is a Maastrichtian geologic formation of the Austral Basin in Santa Cruz Province, Argentina. The formation comprises sandstones and conglomerates with abundant tuff beds. The formation is overlain by the Slogget and San Julián Formations and overlies the Divisadero and Kachaike Formations. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Cerro Castillo Formation is a Jurassic geologic formation in Argentina. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Jingxing Formation is a Mesozoic geologic formation in China. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Turney Ranch Formation is a Mesozoic geologic formation. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Sengoku Formation is an Early Cretaceous geologic formation. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered 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 Dabrazhin Formation preserves dinosaur fossils in Kazakhstan and Tajikistan. There are indeterminate remains of sauropods, nodosaurs, ornithomimosaurs, and other reptiles.
