Cetiosaurus meaning 'whale lizard', from the Greek keteios/κήτειος meaning 'sea monster' and sauros/σαυρος meaning 'lizard', is a herbivorous sauropod dinosaur from the Middle Jurassic Period, living about 167 million years ago in what is now Europe.
Lapparentosaurus is a genus of sauropod dinosaur from the Middle Jurassic. Its fossils were found in Madagascar. The type species is L. madagascariensis.
Piveteausaurus is a genus of theropod dinosaur known from a partial skull discovered in the Middle Jurassic Marnes de Dives formation of Calvados, in northern France and lived about 164.7-161.2 million years ago. In 2012 Thomas Holtz gave a possible length of 11 meters.
Lourinhasaurus was an herbivorous sauropod dinosaur genus dating from Late Jurassic strata of Estremadura, Portugal.
The Argana Group is a geological group in the western High Atlas northeast of Agadir, Morocco. It dates back to the Late Triassic. The group contains the Timezgadiouine Formation.
The Marnes de Dives is a geological formation in Normandy, France. It dates back to the upper part of the Callovian stage of the Middle Jurassic. And is partially equivalent to the Oxford Clay in England. It predominantly consists of ooidal marl, rich in pyrite and lignite, interbedded with thin limestone horizons. It is best exposed at the base of the Falaises des Vaches Noires as well as the foreshore at low tide. It is known for its fossils, notablity those of ammonites, marine crocodiles and fragmentary remains of dinosaurs, mostly theropods.
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 Forest Marble is a geological formation in England. Part of the Great Oolite Group, it dates to back to the late Bathonian stage of the Middle Jurassic.
The Isalo III Formation is a geological formation in Madagascar, off the eastern coast of Africa. It dates back to the Middle Jurassic. The use of the term "Isalo III" is somewhat controversial as the two prior units Isalo I and II are Triassic cross-bedded sandstone units that form a continuous depositional sequence, while the "Isalo III" sandstones are not part of the same depositional sequence, and were deposited considerably later. and are perhaps better treated as part of several separate formations. It is traditionally divided into two subunits the lower, Bajocian aged Isalo IIIa unit also known as the Beronono Formation and the upper, Bathonian aged Isalo IIIb unit also known as the Sakaraha Formation or Sakahara Formation. The Sakaraha Formation consists of sandstones, marls and carbonates and represents a coastal plain environment, and is laterally equivalent to the predominantly carbonate Bemaraha Formation, which represents a coastal barrier lagoon complex. The formation is found in the northwest and in the southeast of the country and has provided a variety of fossils.
The Echkar Formation is a geological formation comprising sandstones and claystones in the Agadez Region of Niger, central Africa.
The Tiourarén Formation is a geological formation in the Agadez Region of Niger whose strata were originally thought to be Early Cretaceous. However, re-interpretation of the sediments showed that they are probably Middle Jurassic (Bathonian) in age. It is the uppermost unit of the Irhazer Group. Dinosaur remains are among the fossils that have been recovered from the formation.
Tizi-n-Aït tracksite is a fossil trackway location in Morocco in the Azilal province. It is Jurassic in age, with tracks attributed to sauropods or stegosaurs, and an unidentified carnosaur. The tracksite is part of the Aganane Formation and the tracks are located at base of formation.
The Balabansai Formation is a geological formation in Kazakhstan, Kyrgyzstan and Uzbekistan whose strata date back to the Bathonian and Callovian stages of the Middle Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation. The lithology primarily consists of variegated sandstones, siltstones, claystones, and rare gravels and marls. Many taxa have been found in the formation, including amphibians and mammals
The Cornbrash Formation is a Middle Jurassic geological formation in England. It ranges in age from Bathonian to Callovian, the uppermost part of the Middle Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The name Cornbrash is an old English agricultural name applied in Wiltshire to a variety of loose rubble or brash which, in that part of the country, forms a good soil for growing corn. The name was adopted by William Smith for a thin band of shelly limestone which, in the south of England, breaks up in the manner indicated. Although only a thin group of rocks, it is remarkably persistent; it may be traced from Weymouth to the Yorkshire coast, but in north Lincolnshire it is very thin, and probably dies out in the neighborhood of the Humber. It appears again, however, as a thin bed in Gristhorpe Bay, Cayton Bay, Wheatcroft, Newton Dale and Langdale. In the inland exposures in Yorkshire it is difficult to follow on account of its thinness, and the fact that it passes up into dark shales in many places the so-called clays of the Cornbrash, with Avicula echinata. The Cornbrash is of little value for building or road-making, although it is used locally; in the south of England it is not oolitic, but in Yorkshire it is a rubbly, marly, frequently ironshot oolitic limestone. In Bedfordshire it has been termed the Bedford limestone.
The Patcham Formation or Pachchham Formation is a Bathonian geologic formation of Patcham Island, Kutch district, Gujarat, India. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
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 Aganane Formation is a Pliensbachian geologic formation in Morocco. Fossil stegosaur and theropod tracks have been reported from the formation.
The Irhazer Shale or Irhazer II Formation is a Middle Jurassic geologic formation of the Irhazer Group in the Agadez Region of Niger. Fossil ornithopod tracks have been reported from the formation. The dinosaur Spinophorosaurus is known from the formation.
The Azilal Formation, also known as Toundute Continental Series and Wazzant Formation, is a geological unit in the Azilal & Ouarzazate provinces of the High Atlas of Morocco, that cover the early Toarcian to early Aalenian stages of the Jurassic Period. It is a terrestrial deposit which overlies marine dolomites of equivalent age to the Budoš Limestone of Montenegro or the Marne di Monte Serrone of Italy. Dinosaur remains, such the sauropod Tazoudasaurus and the basal ceratosaur Berberosaurus are known from the unit, along with several undescribed genera. The Units inside the group have been considered individual on the past, being a division of the so-called "Couches rouges", and subdivided by a supposed geological scale. The strata of the group extends towards the Central High Atlas, covering different anticlines, and topographic accidents along the range of the Mountains. Although new studies have suggested that the strata is coeval in age, and should be referred to as a unique unit. The Group is believed to have been a mostly deltaic, and river channels filled a succession of seashore and inland environments, covering the late Liassic coast of modern northern Africa. Based on observed halokinetic strata, the Tazoult Ridge evolved as a Salt Wall forming a 20 km long NE-SW trending structural and sedimentary high for at least 20 million years, between Pliensbachian-Bajocian periods. This emerged small landmass generated a great local diapir, with continuous Diapirism until the end of the Aalenian.
