The Berivotra Formation is a Maastrichtian sedimentary formation of the Mahajanga Basin in Boeny, Madagascar. The claystones of the formation were deposited in a shallow marine environment. The Berivotra Formation overlies the fossil-rich Maevarano Formation, in which more fossils of Beelzebufo, also recovered from the Berivotra Formation, have been found. Many shark and ray teeth were collected by surface prospecting on outcrops of the Berivotra Formation, which is readily distinguished by its yellowish grey to pale olive colour, as opposed to the white and green fluvial sandstones that form the upper 15 to 20 metres of the underlying Maevarano Formation.
The Severn Formation is a Mesozoic geologic formation in Maryland. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Melovatka or Melovatsskaya Formation is a Cenomanian geologic formation in Russia. Pterosaur fossils have been recovered from the formation.
The Choptank Formation is a geologic formation in Virginia and Maryland. It preserves fossils dating from the Miocene epoch of the Neogene period.
The Nanjemoy Formation is a geologic formation pertaining to both the Wilcox Group and the Pamunkey Group of the eastern United States, stretching across the states of Virginia, Maryland, and District of Columbia. The formation crops out east of the Appalachians and dates back to the Paleogene period. Specifically to the Ypresian stage of the Eocene epoch, about 55 to 50 Ma or Wasatchian in the NALMA classification, defined by the contemporaneous Wasatch Formation of the Pacific US coast.
The Alachua Formation is a Miocene geologic formation in Florida. The claystones, sandstones and phosphorites of the formation preserve many fossils of mammals, birds, reptiles and fish, among others megalodon.
The Bashi Formation is a geologic formation in Alabama and Mississippi. It is named for Bashi Creek in northern Clarke County, Alabama, which cuts through some of its exposures. It preserves fossils dating back to the Eocene period, or Wasatchian in the NALMA classification.
The Tirabuzon Formation is a geologic formation in Mexico. It preserves fossils dating back to the Neogene period, Pliocene epoch.
The Almejas Formation is a geologic formation in Mexico. It preserves fossils dating back to the Late Miocene to Early Pliocene of the Neogene period.
The Marne de Flize is a geologic formation in France. It preserves fossils dating back to the Toarcian stage of the Jurassic period.
The Allgäu Formation is a geologic formation in Austria, Germany and Slovakia. It preserves fossils dating back to the Hettangian to Sinemurian stages of the Early Jurassic period, or Raricostatum to Obtusum in the regional stratigraphy. Initially and formally defined by Jacobshagen (1965). The Allgäu Formation is formerly known as spotted marls (Lias-Fleckenmergel) and spotted marly limestones (Fleckenkalk). The formation is represented by dark-grey bioturbated limestones and marlstone interbeds. It represents basinal hemipelagic facies common in Alpine Tethys regions of Alps, Carpathians and other mountain ranges. Several horizons of the formation are particularly rich in ammonite fauna.
The Weissenegg Formation is a geologic formation in Austria. It preserves fossils dating back to the Miocene period.
The Trogkofel Formation is a geologic formation in Austria, Slovenia and Italy. It preserves fossils dating back to the Sakmarian to Artinskian stages of the Permian period.
The Dachstein Formation or Dachstein Limestone is a geologic formation in the Alps and other Tethyan mountain ranges in Austria, Germany, Hungary, Italy, Switzerland, Slovakia and Slovenia. It preserves fossils dated to the Norian and Rhaetian stages of the Late Triassic period.
The Partnach Formation is a Middle Triassic geologic formation in the eastern Northern Limestone Alps and Western Carpathians, within Austria and Slovakia, Central Europe. The formation consists of alternating grey and green marls and shales and grey limestones, often brecciated, oncolithic and containing clay intraclasts. The formation is gradually evolving from the Reifling Formation. It is usually overlain by the Lunz/Reibl Formation or Wetterstein Formation. Sediments of the Partnach Formation were deposited in intrashelf basins.
The Moskvoretskaya Formation is a Middle Jurassic geologic formation in the European part of Russia. It consists of continental claystones, siltstones and sandstones deposited in karstified segments of underlying Middle Carboniferous limestone, that would have formed underground aquifers.
The Langental Formation, also spelled as Langetal Formation, is a Late Eocene geologic formation cropping out in the Sperrgebiet, ǁKaras Region of southwestern Namibia. The siltstones and sandstones of the formation were deposited in a shallow marine environment. The Langental Formation was deposited under hot and humid conditions. The formation overlies the Silica Beds unit and is overlain by the Blaubok Conglomerate. The Langental Formation provides many fossil invertebrates and fish.
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 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 Calvert Formation is a geologic formation in Maryland, Virginia, and Delaware. It preserves fossils dating back to the early to middle Miocene epoch of the Neogene period. It is one of the three formations which make up the Calvert Cliffs, all of which are part of the Chesapeake Group.
