The Fort Terrett Formation is a Mesozoic geologic formation in Texas. Fossil theropod tracks have been reported from the formation. [1]
Kelmayisaurus is an extinct genus of carcharodontosaurid theropod dinosaur from the Early Cretaceous. It was roughly 10–12 meters long and its name refers to the petroleum-producing city of Karamay in the Xinjiang province of western China near where it was found.
The Arundel Formation, also known as the Arundel Clay, is a clay-rich sedimentary rock formation, within the Potomac Group, found in Maryland of the United States of America. It is of Aptian age. This rock unit had been economically important as a source of iron ore, but is now more notable for its dinosaur fossils. It consists of clay lenses within depressions in the upper part of the Patuxent Formation that may represent oxbow swamp facies. It is named for Anne Arundel County, Maryland.
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 Newark Canyon Formation is a Mesozoic geologic formation in Nevada in the United States.
The East Berlin Formation is an Early Jurassic geological formation in New England, United States. Dinosaur footprints and trackways are abundant in this formation. These tracks include Eubrontes, Anchisauripus, and Anomoepus. Several museums, parks, and tourist attractions are based around the East Berlin Formation's dinosaur tracks, including Dinosaur State Park in Rocky Hill, Connecticut and Powder Hill Dinosaur Park in Middlefield, Connecticut.
The Iouaridène Formation is a Mesozoic geologic formation in Morocco. Fossil sauropod and theropod tracks have been reported from the formation. It is part of the 'Red Beds' of Morocco alongside the Guettioua Sandstone and Jbel Sidal Formation. The lithology consists of cyclic alternation of meter scale red mudstones and 10's of cm scale carbonate cemented mudstones to very fine sandstones.
The Lealt Shale Formation is a Middle Jurassic geologic formation in Scotland. Fossil ornithopod, theropod and stegosaur tracks, a theropod dinosaur tooth and the pterosaur Dearc have been reported from the formation. The lithology consists of silty fissile mudstones with subordinate thin limestones.
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 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 Zhiluo Formation is a geological formation in China, it is also alternatively considered a geological group under the name Zhiluo Group. It dates to the Middle Jurassic. It consists of sandstone, mudstone and siltstone of varying colours. It has received scientific attention for its uranium ore bodies present in the lower part of the formation. Fossil theropod tracks have been reported from the formation. These were described from two footprints found in Jiaoping Coal Mine by C. C. Young in 1966 as Shensipus tungchuanensis. These were in 2015 suggested to belong to Anomoepus. The dinosaur Lingwulong has been suggested to have come from the strata of this formation, previously having been attributed to the underlying Yanan Formation.
The Donghe Group is a Lower Cretaceous geologic formation in China. Fossil theropod tracks have been reported from the formation. It predominantly consists of conglomerate, alongside sandstone, siltstone and shale.
The Etjo Sandstone is an Early Jurassic geologic formation in northern Namibia. The formation overlies the Omingonde Formation in the Waterberg Basin and the Doros and Gai-As Formations in the Huab Basin and has a total thickness of 140 metres (460 ft). Fossil theropod tracks of Prosauropoda indet., Theropoda indet., Tetrapodium elmenhorsti, Saurichnium anserinum, S. damarense, S. parallelum and S. tetractis have been reported from the formation, deposited in an aeolian environment.
The Heichengtzu Series is a Mesozoic geologic formation in China. Fossil theropod 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 Piedrahita de Muñó Formation is an Early Cretaceous geologic formation of the Cameros Basin in northern Spain. Fossil theropod tracks have been reported from the formation. Also fossils of Lepidotes sp., Polacanthus sp. and Testudines indet. were found in the formation.
The Quarziti Viola Zonate Formation is a Mesozoic geologic formation in Italy. Fossil theropod tracks have been reported from the formation.
The Segovia Formation is a Cretaceous geologic formation. Fossil theropod tracks have been reported from the formation.
The Shemshak Formation is a Mesozoic geologic group in Iran. It dates from the Late Triassic into the Middle Jurassic, is up to 4000m thick and primarily consists of siliciclastic sediments. Fossil theropod tracks have been reported from Dansirit Formation.
The Stockton Beds is a Mesozoic geologic formation in the northeastern United States. Fossil theropod tracks have been reported from the formation.
The De Queen Formation, formerly known as the DeQueen Limestone Member is a Mesozoic geological formation located in southwestern Arkansas and southeastern Oklahoma in the United States. Fossil sauropod and theropod tracks have been reported from the formation. It preserves fossils dating back to the Cretaceous period, particularly the Albian age.
