The Wealden Group, occasionally also referred to as the Wealden Supergroup, is a group in the lithostratigraphy of southern England. The Wealden group consists of paralic to continental (freshwater) facies sedimentary rocks of Berriasian to Aptian age and thus forms part of the English Lower Cretaceous. It is composed of alternating sands and clays. The sandy units were deposited in a flood plain of braided rivers, the clays mostly in a lagoonal coastal plain.
The Glen Rose Formation is a shallow marine to shoreline geological formation from the lower Cretaceous period exposed over a large area from South Central to North Central Texas. The formation is most widely known for the dinosaur footprints and trackways found in the Dinosaur Valley State Park near the town of Glen Rose, Texas, southwest of Fort Worth and at other localities in Central Texas.
The Twin Mountains Formation, also known as the Twin Mak Formation, is a sedimentary rock formation, within the Trinity Group, found in Texas of the United States of America. It is a terrestrial formation of Aptian age, and is notable for its dinosaur fossils. Dinosaurs from this formation include the large theropod Acrocanthosaurus, the sauropod Sauroposeidon, as well as the ornithopods Tenontosaurus and Convolosaurus. It is the lowermost unit of the lower Cretaceous, lying unconformably on Carboniferous strata. It is overlain by the Glen Rose Formation. It is the lateral equivalent of the lower part of the Antlers Formation.
The Urbión Group is a geological group in Castile and León and La Rioja, Spain whose strata date back to the Early Cretaceous (late Hauterivian to late Barremian. The formations of the group comprise a sequence of brown limestones in a matrix of black silt, sandstones, claystones and conglomerates deposited under terrestrial conditions, in alluvial fan and fluvial environments.
The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous. The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from 300 to 800 metres, were deposited in fluvial, deltaic and lacustrine environments.
The Grès supérieurs Formation is a geological formation in Laos whose strata date back to the Aptian to Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. It is equivalent to the Khok Kruat Formation of Thailand.
The Koum Formation is a geological formation in the North Province of Cameroon, western Africa.
The Dinosaur Beds is a geological formation in Malawi whose strata date back to the Early Cretaceous. The age of the deposit is poorly constrained, but is likely to date from the Barremian to Aptian. Dinosaurs, turtles and crocodylomorphs remains are among the fossils that have been recovered from the formation. It is correlated with the Galula Formation in Tanzania. It consists of two members, a lower unfossiliferous member consisting of deep red stained sandstones, and an upper fossiliferous member consisting of white sands and grey to red mudstones and siltstones. The upper member is 210 m thick in the vicinity of the CD-9 locality.
The Itapecuru Formation is a geological formation in Itapecuru Mirim, Maranhão, Brazil.
The Moenave Formation is a Mesozoic geologic formation, in the Glen Canyon Group. It is found in Utah and Arizona.
The Caranguejeira Conglomerate is an Aptian to Cenomanian geologic formation in Portugal. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Vega Formation is a Late Jurassic (Kimmeridgian) geologic formation of the Ribadesella Group in Asturias, Spain. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation is around 150 metres thick and consists of "alternating white, pale grey and reddish sandstones, and red mudstones with several sporadic conglomeratic beds typically arranged in minor finnig-upward cycles within a major cycle of the same character". An isolated caudal theropod vertebra and a partial tooth are known from the formation, belonging to large megalosaurids around 10 metres in length, comparable to Torvosaurus. Other remains known from the formation include fragmentary turtle remains, crocodylomorph teeth, as well as a sauropod caudal vertebra (MUJA-0650). Dinosaur tracks are also known from the formation, including large theropod footprints and poorly preserved quadrupedal dinosaur footprints.
The Calcare di Altamura is a Coniacian to early Campanian geologic formation in Italy. The formation comprises limestones that are highly fractured, in places karstified and dolomitized. Fossil ankylosaur tracks have been reported from the formation.
The Montemarcello Formation is a Late Triassic (Carnian) geologic formation in Liguria, Italy. Fossil prosauropod tracks have been reported from the formation.
The Higueruelas (Spanish) or Higuerueles Formation (Catalan) is a Tithonian geologic formation in the Teruel and Valencia provinces of Spain. Fossil sauropod tracks have been reported from the formation.
The Antenor Navarro Formation is an Early Cretaceous geologic formation in Brazil. Fossil sauropod tracks have been reported from the formation.
The San Giovanni Rotondo Formation is an Early Cretaceous geologic formation in Italy. Fossil ornithopod tracks have been reported from the formation.
The Jingchuan Formation is a Barremian geologic formation in China. Various dinosaur fossils and tracks have been reported from the formation.
The Calcare di Bari is a Cretaceous geologic formation in Apulia, southeastern Italy. The formation comprises micritic limestones, in places karstified and dolomitized. Rudists and fossil ankylosaur, sauropod and theropod tracks have been reported from the 2,000 metres (6,600 ft) thick formation that was deposited in an inner carbonate platform environment towards the top dominated by rudist reefs.
