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 Castillo Formation is an Early Miocene geologic formation in the Falcón Basin of Venezuela. The formation unconformably overlies the Matatere, Misoa, El Paují and Jarillal Formations. The Castillo Formation is overlain by Quaternary alluvium and in places by the Capadare Formation. The formation, deposited in a calm near-shore lagoonal brackish environment, with possibly fluvial influence, has provided a rich assemblage of fossil crocodylians, turtles, giant sloths and various types of fish.
The Malargüe Group is a group of geologic formations of the Neuquén Basin of the Mendoza, Neuquén, Río Negro and La Pampa Provinces in northern Patagonia, Argentina. The formations of the Malargüe Group range in age between the middle Campanian to Deseadan, an Oligocene age of the SALMA classification, straddling the Cretaceous–Paleogene boundary, about 79 million to 30 million years in age. The group overlies the older Neuquén Group, separated by an unconformity dated to 79 Ma. The rocks of the Malargüe Group comprise both marine and continental deposits which are over 400 m (1312 ft) thick in total.
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 Tatman Formation is a Wasatchian geologic formation in Wyoming. It preserves fossils dating back to the Ypresian stage of the Eocene period.
The Margaret Formation is a geologic formation of the Eureka Sound Group in the Sverdrup Basin in Northwest Territories and Nunavut, Canada. The unit belonging to the Eureka Sound Group which crops out at Ellesmere Island preserves fossils dating back to the Early Eocene period, or Wasatchian in the NALMA classification.
Charco Azul Formation is a geologic formation of the Charco Azul Group in western Panama and southeastern Costa Rica. It preserves gastropod fossils dating back to the Pliocene period.
The Charco Azul Group is a geologic group in southeastern Costa Rica and western Panama. The group comprises the Armuelles, Penita and Charco Azul Formations and preserves fossils.
The Pebas Formation is a lithostratigraphic unit of Miocene age, found in western Amazonia. The formation extends over 1,000,000 square kilometres (390,000 sq mi), including parts of Brazil, Peru, Ecuador and Colombia. It is interpreted as representing the deposits of a lake or series of lakes, formed within the foreland basin of the Andes mountain belt. It is known for its abundant fossil ostracods and molluscs and an unusually diverse group of crocodylians.
Mangelia heptapleura is an extinct species of sea snail, a marine gastropod mollusc in the family Mangeliidae.
Mangelia hesperia is an extinct species of sea snail, a marine gastropod mollusc in the family Mangeliidae.
The Elisabeth Bay Formation, alternatively spelled as Elizabeth Bay Formation, is an Early Miocene geologic formation in the Sperrgebiet, ǁKaras Region of southwestern Namibia, overlying the Blaubok Conglomerate. The freshwater green and red siltstones, sandstones, intercalations of conglomerates and claystones of the formation were deposited in a fluvial environment, infilling a paleovalley incised during the Oligocene low sea stand, which backfilled during the Burdigalian marine transgression. The Elisabeth Bay Formation provides many fossil mammals, snakes and other reptiles.
The Jama Formation is a Pliocene to Early Pleistocene geological formation in Ecuador. The claystones and sandstones were deposited in a coastal environment. The age of the Jama Formation is constrained by 40Ar/39Ar dating of tephra beds. The formation is correlated to the Charco Azul Formation of western Panama and southeastern Costa Rica.
The Onzole Formation is an Early Pliocene geologic formation in the Borbón Basin of northwestern Ecuador. The formation consists of a shallow marine sandstone member containing many fish fossils, among which megalodon, and a deep water member comprising tuffaceous shales and mudstones containing gastropods, bivalves and scaphopods.
The Viche Formation is a Langhian geologic formation of the Borbón Basin in northwestern Ecuador. The formation underlies the Angostura Formation. Fossils of Ziphiidae indet. have been found in the formation.
The Letrero Formation is a Late Miocene geologic formation in south-central Ecuador. The formation comprises lacustrine sediments with strong fluvial clastic input and contains siltstones and fine-grained sandstones.
The El Molino Formation is a Maastrichtian geologic formation pertaining to the Puca Group of central Bolivia. The formation comprises fine-grained sandstones and sandy limestones with stromatolites deposited in a shallow marine to lacustrine environment. The formation has provided fossils of Dolichochampsa minima, and ichnofossils of Ankylosauria indet., Ornithopoda indet., Theropoda indet. and Titanosauridae indet. The tracksite of Cal Orcko is the best known example of the ichnofossil locations of the formation. The ichnofossil of Ligabueichnum bolivianum may be attributed to an ankylosaur. The fossil fish species Dasyatis molinoensis is named after the formation.
The Aïn el Guettar Formation is a geological formation in Tunisia, whose strata date back to the Late Aptian to Early Albian stages of the Cretaceous period. The lithology consists of coarse sandstones with occasional conglomerates and mudstones. Dinosaur remains are among the fossils that have been recovered from the formation.
