Antarctopelta is a genus of ankylosaurian dinosaur, a group of large, quadrupedal herbivores, that lived during the Maastrichtian stage of the Late Cretaceous period on what is now James Ross Island, Antarctica. Antarctopelta is the only known ankylosaur from Antarctica and a member of Parankylosauria. The only described specimen was found in 1986, the first dinosaur to be found on the continent, by Argentine geologists Eduardo Olivero and Robert Scasso. The fossils were later described in 2006 by paleontologists Leonardo Salgado and Zulma Gasparini, who named the type species A. oliveroi after Olivero.
The Lopez de Bertodano Formation is a geological formation in the James Ross archipelago of the Antarctic Peninsula. The strata date from the end of the Late Cretaceous to the Danian stage of the lower Paleocene, from about 70 to 65.5 million years ago, straddling the Cretaceous-Paleogene boundary.
The Sobral Formation is a palaeontological formation located in Antarctica. It dates to the Danian stage of the Lower Paleocene period.
The Ankarafantsika Formation is a Late Cretaceous (Cenomanian) geologic formation of the Mahajanga Basin in the Boeny region of Madagascar, Africa. The fine-grained sandstones of the formation were deposited in a fluvial to lacustrine environment.
The Birdrong Sandstone is an Early Cretaceous geologic formation of the Barrow Group in Western Australia. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Chilgog Formation, also known as the Chilgok Formation, is an Early Cretaceous geologic formation in South Korea. Formerly dated to the Berriasian to Hauterivian, later dating has established an Albian age. Dinosaur remains, possibly of sauropods, are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Iljig Formation is a Lower Cretaceous geologic formation in South Korea. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The In Beceten Formation, also Beceten or Ibecten is a Coniacian to Santonian geologic formation in the Iullemmeden Basin of Niger. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The lithology primarily consists of clays, fine limestones and sandy clays.
The Hornitos Formation is a Campanian geologic formation of the Algarrobal Basin in the Atacama Region of northern Chile. The formation comprises limestones, sandstones, conglomerates, marls and tuff. Dinosaur remains are among the fossils that have been recovered from the formation, including the sauropod Arackar licanantay.
The Mifune Group or Mihune Formation is a Mesozoic geologic formation in Japan. It contains dinosaur fossils.
The Molecap Greensand is a Late Cretaceous geologic formation, located in the state of Western Australia in Australia.
The Oum ed Diab Member is a middle-upper Albian geologic member, part of the Ain el Guettar Formation of Tunisia. Dinosaur remains are among the fossils that have been recovered from the formation.
The Quantou Formation is a Cretaceous Period geologic formation in China. It is primarily Albian in age. It has been explored for its potential as a tight oil reservoir.
The Shendi Formation is a Late Cretaceous geologic formation of the Atbara-Shendi Basin in northern Sudan. Indeterminate theropod remains have been recovered from it. As well as those of the dyrosaurid Hyposaurus. It consists of a lower unit of fine grained meandering channel sediments, separated by an erosive contact with overlying meandering to braided river channel sandstones.
The Sierra Perenchiza Formation is a late Campanian to late Maastrichtian geologic formation in Spain. Dinosaur, pterosaur, turtle, lissamphibian, frog and albanerpetontid remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus and the crocodylomorphs Acynodon, Doratodon ibericus and Musturzabalsuchus are also known from this formation.
The Abu Agag Formation is a Turonian geologic formation in Egypt and Sudan. Indeterminate fossil ornithischian tracks have been reported from the formation.
The Rupelo Formation is an Early Cretaceous (Berriasian) geologic formation in the Burgos Province of Castile and León in northern Spain. The formation crops out near the municipality Mambrillas de Lara in the northwesternmost part of the Cameros Basin in the Sierra de la Demanda.
The Snow Hill Island Formation is an Early Maastrichtian geologic formation found on James Ross Island, James Ross Island group, Antarctica. Remains of a paravian theropod Imperobator antarcticus have been recovered from it, as well as the elasmarian ornithopods Trinisaura santamartaensis, "Biscoveosaurus" and Morrosaurus antarcticus, the ankylosaurian Antarctopelta oliveroi, and the shark Notidanodon sp. Alongside these described genera are also the remains of indeterminate elasmosaurids, lithostrotian titanosaurs and an indeterminate pterosaur.
Imperobator is a genus of probable unenlagiid paravian theropod dinosaurs, that lived during the Maastrichtian age of the Late Cretaceous period in what is now James Ross Island in Antarctica. Imperobator is one of only two non-avian theropods known from Antarctica, crossing over to the landmass when it was part of Gondwana. The only described specimen was found in 2003 by an expedition launched by the University of California Museum of Paleontology and initially described as a dromaeosaur in 2007. The fossil was formally described as a new genus in 2019, and later searches reported more fossils from the site including teeth and skull bones.
