WThe Allgäu Formation is a geologic formation in Austria. It preserves fossils dating back to the Hettangian to Sinemurian stages of the Early Jurassic period, or Raricostatum to Obtusum in the regional stratigraphy. Initially and formally defined by Jacobshagen (1965). The Allgäu Formation is formerly known as spotted marls (Lias-Fleckenmergel) and spotted marly limestones (Fleckenkalk). The formation is represented by dark-grey bioturbated limestones and marlstone interbeds. It represents basinal hemipelagic facies common in Alpine Tethys regions of Alps, Carpathians and other mountain ranges. Several horizons of the formation are particularly rich in ammonite fauna.
WThe Bagå Formation is a geological formation dating to around 199 to 170 million years ago, in the Early and Late Jurassic. It is located on the island of Bornholm, Denmark.

WThe 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.
WThe Elliot Formation is a geological formation and forms part of the Stormberg Group, the uppermost geological group that comprises the greater Karoo Supergroup. Outcrops of the Elliot Formation have been found in the northern Eastern Cape, southern Free State, and in the eastern KwaZulu-Natal provinces of South Africa. Outcrops and exposures are also found in several localities in Lesotho such as Qacha's Neck, Hill Top, Quthing, and near the capital, Maseru. The Elliot Formation is further divided into the lower (LEF) and upper (UEF) Elliot formations to differentiate significant sedimentological differences between these layers. The LEF is dominantly Late Triassic (Norian-Rhaetian) in age while the UEF is mainly Early Jurassic (Hettangian) and is tentatively regarded to preserve a continental record of the Triassic-Jurassic boundary in southern Africa. This geological formation is named after the town of Elliot in the Eastern Cape, and its stratotype locality is located on the Barkly Pass, 9 km north of the town.
WThe Feltville Formation is a mapped bedrock unit primarily in New Jersey, with one known outlier in Pennsylvania and another one in New York.

WThe Hanson Formation is a geologic formation on Mount Kirkpatrick, Antarctica. It is one of only two major dinosaur-bearing rock groups found on the continent of Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula. The formation has yielded only a handful of Mesozoic specimens so far and most of it is as yet unexcavated. Part of the Victoria Group of the Transantarctic Mountains, it is below the Prebble Formation and above the Falla Formation. The Formation is related to the Volcanic Activity Linked to the Karoo-Ferar eruptions on the Lower Jurassic. The climate of the zone was similar to the modern Southern Chile, Humid, with a temperature interval of 17–18 degrees.
WThe Höganäs Formation is a Late Triassic to Early Jurassic geologic formation in Skåne, Sweden. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
WThe Kota Formation is a geological formation in India. The precise age of Kota Formation are uncertain, but it dates from the Early to Middle Jurassic, and is split into a Lower Member and Upper Member. The lower member is thought to be Hettangian-Pliensbachian. While the upper unit is thought to be Toarcian, but may possibly extend into the Aalenian. It conformably overlies the Dharmaram Formation which is Late Triassic to earliest Jurassic and is unconformably overlain by the Early Cretaceous Gangapur Formation. The lower member is approximately 100 m thick while the upper member is 490 m thick. Both subunits primarily consist of mudstone and sandstone, but near the base of the upper unit there is a 20-30 metre thick succession of limestone deposited in a freshwater setting.
WThe La Quinta Formation is a Jurassic geologic formation which crops out in the Cordillera de Mérida and Serranía del Perijá of western Venezuela and northeastern Colombia. The formation is also present in the subsurface of the Cesar-Ranchería and Maracaibo Basins. At its type locality near La Grita, Táchira, it consists of a basal dacitic tuff followed by interlayered sandstones, tuffs, siltstones and rare limestones. Dinosaur remains including Laquintasaura, and Tachiraptor, are among the fossils that have been recovered from the formation.
WThe Lufeng Formation is a Lower Jurassic sedimentary rock formation found in Yunnan, China. It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age. It is known for its fossils of early dinosaurs. The Dull Purplish Beds have yielded the possible therizinosaur Eshanosaurus, the possible theropod Lukousaurus, and the "prosauropods" "Gyposaurus" sinensis, Lufengosaurus, Jingshanosaurus, and Yunnanosaurus. Dinosaurs discovered in the Dark Red Beds include the theropod Sinosaurus triassicus, the "prosauropods" "Gyposaurus", Lufengosaurus, and Yunnanosaurus, indeterminate remains of sauropods, and the early armored dinosaurs Bienosaurus and Tatisaurus.
