The Winton Formation is a Cretaceous geological formation in central-western Queensland, Australia. It is late Albian to early Turonian in age. The formation blankets large areas of central-western Queensland. It consists of sedimentary rocks such as sandstone, siltstone and claystone. The sediments that make up these rocks represent the remnants of the river plains that filled the basin left by the Eromanga Sea - an inland sea that covered large parts of Queensland and central Australia at least four times during the Early Cretaceous. Great meandering rivers, forest pools and swamps, creeks, lakes and coastal estuaries all left behind different types of sediment.
The Wayan Formation is a geological formation in Idaho whose strata date back to the latest Early Cretaceous and the earliest Late Cretaceous. Dinosaur, other reptile, mammal, and micro and macro-floral remains are among the fossils that have been recovered from the formation. The lack of extensive outcrops, limited geographic extent, and extreme structural deformation have limited paleontological explorations of the Wayan.
The Escucha Formation is a geological formation in La Rioja and Teruel provinces of northeastern Spain whose strata date back to the late Aptian to middle Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Koum Formation is a geological formation in the North Province of Cameroon, western Africa.
The Aztec Sandstone is an Early Jurassic geological formation of primarily eolian sand from which fossil pterosaur tracks have been recovered. The formation is exposed in the Mojave Desert of Arizona, California and Nevada. Aztec Sandstone is named after the Aztec Tank, a lake in the Spring Mountain region of Nevada.
The Luohandong Formation is an Early Cretaceous geologic formation of the Ordos Basin in Inner Mongolia, China. The formation was initially dated to the earliest Cretaceous; Valanginian to Barremian, but later dating established an Aptian to Albian age. Dinosaur remains are among the fossils that have been recovered from the formation. Pterosaur fossils have also been recovered from the formation.
The Valle de Ángeles Redbeds (Kva) is a Late Albian to Early Cenomanian geologic formation of the in western Honduras. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Mowry Shale is an Early Cretaceous geologic formation. The formation was named for Mowrie Creek, northwest of Buffalo in Johnson County, Wyoming.
The Pajarito Formation is a geologic formation in eastern New Mexico and west Texas. It preserves fossils dating back to the Albian Age of the Cretaceous Period.
The Geoncheonri Formation is an Early Cretaceous (Aptian-Albian) geologic formation of the Hayang Group in the Gyeongsang Basin of southeast South Korea. Fossil ornithopod tracks, as well as fossils of Kirgizemys have been reported from the lacustrine siltstones and mudstones of the formation.
The Jobu Formation is a Cretaceous geologic formation of Late Cenomanian age. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The oldest confirmed tyrannosaurid premaxillary tooth was recovered from the Jobu Formation. The mammal Sorlestes is also known from the formation.
Macroelongatoolithus is an oogenus of large theropod dinosaur eggs, representing the eggs of giant caenagnathid oviraptorosaurs. They are known from Asia and from North America. Historically, several oospecies have been assigned to Macroelongatoolithus, however they are all now considered to be a single oospecies: M. carlylensis.
The Aoufous Formation is a geological formation that contains some of the vertebrate assemblage of the Kem Kem Group, of Late Cretaceous date. Two other formations comprise the Kem Kem beds: the underlying Ifezouane Formation and the overlying Akrabou Formation.
The Blackleaf Formation is a geologic formation in Montana. It preserves fossils dating back to the Albian to Cenomanian stages of the Cretaceous period.
The McKay Formation is a geologic formation in Oregon. It preserves fossils dating back to the Tortonian to Zanclean stages (Hemphillian) of the Neogene period.
The Sierra Madre Formation is a geologic formation in Chiapas state, southern Mexico. It consists of marine dolomites and limestones. The formation dates to the Middle Cretaceous, spanning from the Aptian of the Early to the Cenomanian of the Late Cretaceous.
The Liangtoutang Formation, also referred to as the Laijia Formation is a geological formation located in Zhejiang, China. Its strata date back to the Albian to Cenomanian stages of the Cretaceous period. The lithology primarily consists of red sandstone.
The Açu Formation is an Early Cretaceous (Albian) geologic formation of the Potiguar Basin in Ceará, northeastern Brazil. The formation comprises coarse-grained sandstones deposited in a fluvio-deltaic environment. The Açu Formation, belonging to the Apodi Group, has provided fossils of an indeterminate rebbachisaurid.
Nevadadromeus is an extinct genus of small thescelosaurine ornithischian dinosaur, from the Willow Tank Formation of Nevada, United States. The genus contains a single species, N. schmitti, which represents the first non-avian dinosaur named from Nevada.
