The Chipping Norton Limestone is a geological formation in the Cotswolds, England. It preserves fossils dating back to the Bathonian (Middle Jurassic). [1] [2] Including those of dinosaurs Cetiosaurus, Megalosaurus and Cruxicheiros as well as the Tritylodontid Stereognathus . It primarily consists of ooidal limestone.
The so-called "Scrotum humanum" remains may have come from this formation. [1]

Phyllodon was a genus of small ornithischian dinosaur from the Kimmeridgian-aged Upper Jurassic Camadas de Guimarota Formation of Leiria, Portugal and possibly also the Bathonian-aged Chipping Norton Limestone of England. It may have been closely related to contemporaneous dinosaurs in North America.
The Bushveld Sandstone is a geological formation dating to roughly between 201 and 189 million years ago and covering the Carnian to Norian stages. The Bushveld Sandstone is found in Transvaal, South Africa, and is a member of the Stormberg Group. As its name suggests, it consists mainly of sandstone. Fossils of the prosauropod dinosaur Massospondylus have been recovered from the Bushveld Sandstone.
The Löwenstein Formation is a lithostratigraphic formation of the Keuper in Germany. It is underlain by the Mainhardt Formation and overlain by the Trossingen Formation. It dates back to the middle Norian.
The Moon-Airel Formation is a geological formation in France. It dates back to the late Rhaetian and early Hettangian.
The Calcaire de Caen or Calcaires de Caen Formation; French for Caen Limestone, is a geological formation in France. It dates back to the mid-Bathonian of the Jurassic. It was often quarried for building work and is referred to as Caen Stone.
The Taynton Limestone is a geological formation in Oxfordshire in the United Kingdom. It dates to the Middle Jurassic, mid-Bathonian stage. It predominantly consists of ooidal grainstone. The term "Stonesfield Slate" refers to slaty limestone horizons within the formation that during the 18th and 19th centuries were extensively quarried for use in roof tiling within the vicinity of Stonesfield, Oxfordshire. Previously these were thought to belong to the Sharp's Hill Formation, but boreholes and shaft sections suggest that at least three horizons within the Taynton Limestone were quarried for the slate. These horizons are well known for producing a diverse set of fossils including those of plants, insects as well as vertebrates, including some of the earliest known mammals, pterosaurs as well as those of first dinosaur ever described, Megalosaurus.
The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic. The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group in southern and eastern England. It has been variously known in the past as the Under Oolite, the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group.
The Forest Marble is a geological formation in England. Part of the Great Oolite Group, it dates to the late Bathonian stage of the Middle Jurassic.
The Dapuka Group is a geological formation in Asia. It dates back to the Middle Jurassic.
The Guettioua Formation is a geological formation in Morocco. It dates back to the Middle Jurassic. It largely consists of sandstone, and is of continental origin. It is the lateral equivalent of the marine El Mers 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 Bauxite of Cornet is a geological formation in Romania whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. It exists as karstic sediments infilling fissures and caves in limestone.
The Minhe Formation is a geological formation in northwestern China, whose strata date back to the Late Cretaceous period.
The Kalahari Deposits is an Early Cretaceous (Aptian) geologic formation in South Africa. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The depositional environment is described as a crater lake where poorly lithified, concretionary conglomerate and volcaniclastic, intraclastic, calcareous mudstone were deposited under quiet subaqueous conditions, probably a "crater-fill succession above an olivine-melilitie intrusion".
The Sharp's Hill Formation is a Bathonian geologic formation in North Oxfordshire north-east of Milton-under-Wychwood and Minster Lovell in the United Kingdom, dating to around 167 million years ago. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. It is the lateral equivalent of the Rutland Formation and the Fuller's Earth Formation.
The White Limestone Formation is a Bathonian geologic formation in the United Kingdom, dating to the Middle Jurassic, 168.3 to 166.1 million years ago. Fossil sauropod tracks have been reported from the formation. It is the lateral equivalent of the Blisworth Limestone. It predominantly consists of grey-yellow limestone, typically wackestone and packstone with subordinate ooidal grainstone. The Woodeaton Quarry locality has yielded microvertebrates.
The Lower Maleri Formation is a sedimentary rock formation found in Andhra Pradesh and Telangana, India. It is the lowermost member of the Pranhita–Godavari Basin. It is of late Carnian to early Norian age, and is notable for its fossils of early dinosaurs, including the basal saurischian Alwalkeria.
The Rutland Formation is a geologic formation in England. It preserves fossils dating back to the late Bajocian to Bathonian stages in the Jurassic period, about 169 million years ago. It is the lateral equivalent of the Sharp's Hill Formation and the Fuller's Earth Formation. The "Rutland Dinosaur" specimen of Cetiosaurus is known from the formation.
The Coralline Oolite Formation is a limestone formation of Oxfordian age, found in the Cleveland Basin of North Yorkshire, England.
