The Nichkesaisk or Nichkesai Formation is an early Campanian geologic formation in Kyrgyzstan. [1] Fossil dinosaur eggs have been reported from the formation. [2]
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.
The Barun Goyot Formation or Baruun Goyot Formation is a geological formation dating to the Late Cretaceous Period. It is located within and is widely represented in the Gobi Desert Basin, in the Ömnögovi Province of Mongolia.
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 Alcobaça Formation, previously known as the Guimarota Formation, is a geological formation in Portugal. It dates back to the Oxfordian stage of the Late Jurassic. It is an important source of information on the diversity of Late Jurassic mammals. Many of the fossils were collected from the now disused and flooded Camadas de Guimarota coal mine.
The Paw Paw Formation is a geological formation in Texas whose strata date back to the late Albian stage of the Early Cretaceous. Dinosaur remains 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 Gres de Saint-Chinian is a geological formation in Aude and Hérault, France whose strata date back to the Late 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 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 Zhaoying Formation is a Coniacian geologic formation in Henan Province, China. Fossil dinosaur eggs of Ovaloolithus sp. have been reported from the formation.
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 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 Inferieures 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 Ialovachsk or Yalovach Formation is a Santonian geologic formation in Kyrgyzstan, Tajikistan and Uzbekistan. Fossil dinosaur eggs have been reported from the formation.
The Gaogou Formation is a Late Cretaceous (Cenomanian-Turonian) geologic formation in China. Fossil dinosaur eggs, the caenagnathid Beibeilong, and the titanosaur Baotianmansaurus have been reported from the formation.
The Grès d'Alet is a Campanian geologic formation in southern France. Fossil dinosaur eggs have been reported from the formation.
