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 Subashi Formation is a Late Cretaceous formation from the Xinjiang Autonomous Region of western China. Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis. Remains of a sauropod, likely Nemegtosaurus, and a hadrosaurid, likely Jaxartosaurus, have also been found.
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 El Castellar Formation is a geological formation in La Rioja and Teruel, Spain whose strata date back to the possibly the Valanginian to the Barremian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Kallakurichi Formation, alternatively spelled as Kallankurichchi or Kallankurichi Formation, is a geological formation of the Ariyalur Group in Tamil Nadu, southern India whose strata date back to the Maastrichtian stage of the Late Cretaceous. Dinosaur eggs of Megaloolithus cylindricus are among the fossils that have been recovered from the sandy limestones of the formation.
The Minhe Formation is a geological formation in northwestern China, whose strata date back to the Late Cretaceous period.
The Wangshi Group is a geological Group in Shandong, China whose strata date back to the Coniacian to Campanian stages of the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the group.
The Thomas Fork Formation is an Early Cretaceous (Albian) geologic formation in Wyoming. Fossil dinosaur eggs have been reported from the formation.
The Sigou Formation is a Late Cretaceous geologic formation in China. Fossil dinosaur eggs have been reported from the formation, including Dictyoolithus.
The Quxian Formation is a Santonian to Campanian geologic formation in China. Fossil dinosaur eggs have been reported from the formation. It is a unit of the Qujiang Group and dates to the Santonian through early Campanian.
The Nichkesaisk or Nichkesai Formation is an early Campanian geologic formation in Kyrgyzstan. Fossil dinosaur eggs have been reported from the formation.
The Mercedes Formation is a Late Cretaceous geologic formation of the Norte Basin in Uruguay. Fossil dinosaur eggs have been reported from the formation. The formation that reaches a thickness of about 100 metres (330 ft), overlies the Guichón Formation and is overlain by the Asencio Formation.
The Marnes Rouges Inférieures Formation is a Late Cretaceous geologic formation found in the French Pyrenees. It predominantly consists of red mustone, with minor brown mudstone and sandstone. Dinosaurs, dinosaur eggs and avialian stem-birds have been reported from the formation.
The Manrak Formation is a Campanian geologic formation in Kazakhstan. Fossil dinosaur eggs have been reported from the formation.
The Khodzhaosmansk or Khodzhaosman Formation is an Aptian to Albian geologic formation in Kyrgyzstan. Dinosaur remains and fossil dinosaur eggs have been reported from the formation.
The Majiacun Formation is a Santonian to Coniacian geologic formation in China. Dinosaur remains are among the fossils that have been recovered from the formation.
Ovaloolithus is an oogenus of dinosaur egg. Eggs of the genus have been found in China, Mongolia and Utah.
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 Grès d'Alet is a Campanian geologic formation in southern France. Fossil dinosaur eggs have been reported from the formation.
