The Eginsai Formation (Russian: Eginsai Svita) is a geological formation in Kazakhstan whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. [1]
Among others, the following fossils have been reported from the formation:
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 Ulansuhai Formation is a geological formation in Inner Mongolia, north China. Dinosaur remains are among the fossils that have been recovered from the formation.
The Ashville Formation is a geological formation in Saskatchewan and Manitoba whose strata date back to the Late Cretaceous. Dinosaur remains 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, specifically around the Cenomanian to Turonian. 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 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 Trichinopoly Group is a geological formation in India whose strata date back to the Late Cretaceous. It lies between the Ootatoor and Ariyalur Groups. It is broad in its southern extremity but thins as it gradually proceeds northwards as it ultimately meets the Ariyalur Group. Dinosaur remains are among the fossils that have been recovered from the formation.
The Shanyang Formation is a geological formation in Shaanxi 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 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 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 Viñita Formation is a geological formation in Coquimbo, Chile, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Lecho Formation is a geological formation in the Salta Basin of the provinces Jujuy and Salta of northwestern Argentina. Its strata date back to the Early Maastrichtian, and is a unit of the Salta Group. The fine-grained bioturbated sandstones of the formation were deposited in a fluvial to lacustrine coastal plain environment.
The Los Alamitos Formation is a geological formation of the North Patagonian Massif in Rio Negro Province, northwestern Patagonia, Argentina, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Korycanar Formation is a Late Cretaceous geologic formation in the Czech Republic. Archosauromorph remains diagnostic to the genus level are among the fossils that have been recovered from the formation and also dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Sânpetru Formation is an early Maastrichtian geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation. It is located in Romania, near Sânpetru village, part of Sântămăria-Orlea commune. It forms a component of the Hațeg Island fauna.
The Khodzhakul Formation is a Cenomanian aged geologic formation in Uzbekistan. Dinosaur remains are among the fossils that have been recovered from the formation. As well as those of Mammals. It is part of the same stratigraphic succession as the overlying Bissekty Formation.
The Dabrazhin Formation preserves dinosaur fossils in Kazakhstan and Tajikistan. There are indeterminate remains of sauropods, nodosaurs, ornithomimosaurs, and other reptiles.
