The Cedar Mountain Formation is the name given to a distinctive sedimentary geologic formation in eastern Utah, spanning most of the early and mid-Cretaceous. The formation was named for Cedar Mountain in northern Emery County, Utah, where William Lee Stokes first studied the exposures in 1944.
The Cloverly Formation is a geological formation of Early and Late Cretaceous age that is present in parts of Montana, Wyoming, Colorado and Utah in the western United States. It was named for a post office on the eastern side of the Bighorn Basin in Wyoming by N.H. Darton in 1904. The sedimentary rocks of formation were deposited in floodplain environments and contain vertebrate fossils, including a diverse assemblage of dinosaur remains. In 1973, the Cloverly Formation Site was designated as a National Natural Landmark by the National Park Service.
The Maevarano Formation is a Late Cretaceous sedimentary rock formation found in the Mahajanga Province of northwestern Madagascar. It is most likely Maastrichtian in age, and records a seasonal, semiarid environment with rivers that had greatly varying discharges. Notable animal fossils recovered include the theropod dinosaur Majungasaurus, the early bird Vorona, the paravian Rahonavis, the titanosaurian sauropod Rapetosaurus, and the giant frog Beelzebufo.
The Milk River Formation is a sandstone-dominated stratigraphic unit of the Western Canada Sedimentary Basin in southern Alberta, Canada. It was deposited in near-shore to coastal environments during Late Cretaceous time. Based on uranium-lead dating, palynology and stratigraphic relationships, deposition occurred between ~84.1 and 83.6 Ma.
The Alcobaça Formation, previously known as the Guimarota Formation and also known as the Consolação Unit, is a geological formation in Portugal. It dates back to the Kimmeridgian 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 Kalaza Formation is a geological formation in Xinjiang, China whose strata date back to the Late Jurassic. There is some confusion with the stratigraphy of this unit, as the term is used for sediments of equivalent age in both the Junggar Basin and the Turpan Basin. Dinosaur remains are among the fossils that have been recovered from formation.
The Kadzi Formation is a geological formation in Zimbabwe whose strata date back to the Tithonian stage of the Late Jurassic. The conglomeratic sandstones and silty mudstones of the formation were deposited in an alluvial environment. Dinosaur remains are among the fossils that have been recovered from the formation.
The Foremost Formation is a stratigraphic unit of Late Cretaceous (Campanian) age that underlies much of southern Alberta, Canada. It was named for outcrops in Chin Coulee near the town of Foremost and is known primarily for its dinosaur remains and other fossils.
The Aguja Formation is a geological formation in North America, exposed in Texas, United States and Chihuahua and Coahuila in Mexico, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. Fossil palms have also been unearthed here.
The Demopolis Chalk is a geological formation in North America, within the U.S. states of Alabama, Mississippi, and Tennessee. The chalk was formed by pelagic sediments deposited along the eastern edge of the Mississippi embayment during the middle Campanian age of the Late Cretaceous. It is a unit of the Selma Group and consists of the upper Bluffport Marl Member and a lower unnamed member. Dinosaur and mosasaur remains are among the fossils that have been recovered from the Demopolis Chalk.
The Horsethief Sandstone is a Mesozoic geologic formation in Montana. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The southern part of the Two Medicine Formation grades into the brackish water siltstone/sandstone series that compose the Horsethief Formation. To the north the Horsethief Sandstone is equivalent to the Blood Reserve Formation of Alberta, Canada.
The Hornitos Formation is a Campanian geologic formation of the Algarrobal Basin in the Atacama Region of northern Chile. The formation comprises limestones, sandstones, conglomerates, marls and tuff. Dinosaur remains are among the fossils that have been recovered from the formation, including the sauropod Arackar licanantay.
The Lomas Coloradas Formation is a Mesozoic geologic formation in Mexico. Dinosaur remains are among the fossils that have been recovered from the formation, although only a few have yet been referred to a specific genus. Indetermiate hadrosaur remains and indeterminate sauropod remains, most likely belonging to Alamosaurus, have been unearthed here.
The Moenave Formation is a Mesozoic geologic formation, in the Glen Canyon Group. It is found in Utah and Arizona.
The Qagannur Formation is a Mesozoic geologic formation in China. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The informal sauropod "Nurosaurus" is known from this formation.
The Mugher Mudstone is a geologic formation located in Ethiopia. It dates to the Tithonian stage of the Late Jurassic. The lithology consists of gypsum, dolomite and shale alternations at the base, overlain by mudstone intercalated with fine to medium grained sandstone.
The Zhenzhuchong Formation is an Early Jurassic geologic formation in China. Plesiosaur remains are among the fossils that have been recovered from its strata. Remains of the prosauropod Lufengosaurus huenei have been recovered from this formation As well as dinosaur footprints.
The Lossiemouth Sandstone is a Middle to Late Triassic age geological formation. It is exposed on the south side of the Moray Firth near Lossiemouth and near Golspie in Sutherland. Dinosaur remains are among the fossils that have been recovered from the formation.
The Dabrazhin Formation preserves dinosaur fossils in Kazakhstan and Tajikistan. There are indeterminate remains of sauropods, nodosaurs, ornithomimosaurs, and other reptiles.
