WThe Buffelskloof Formation is a geological formation found in the Western Cape province in South Africa. It is the uppermost of the four formations found within the Uitenhage Group of the Algoa Basin. It is considered an informal formation by some of the literature as it is very thin and only outcrops as isolated horizons in the Oudshoorn-Gamtoos, Herbertsdale-Mossel Bay, and Heidelberg-Riversdale Basins. Along the Worcester-Pletmos Basin, it occurs in patches along the southern flanks of the Langeberg mountain range - from Worcester in the west and as far as Mossel Bay in the east. From Mossel Bay this formation is inter fingered by the informal Hartenbos Formation. The Buffelskloof and Hartenbos Formations only occur in the Oudshoorn-Gamtoos and Herbertsdale-Mossel Bay basins and seem to correlate to the Sundays River Formation in age.

WThe 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.
WThe 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.
WThe Itombe Formation is a geological formation of the Kwanza Basin in Angola dating back to the Turonian stage of the Late Cretaceous. The environment of deposition is shallow marine. Reptile fossils have been recovered from the Tadi beds locality within the formation, including the dinosaur Angolatitan, the mosasaurs Angolasaurus and Mosasaurus iembeensis and the turtle Angolachelys. Itombe formation was considered Turonian in age, but new data suggests to be Coniacian.
WThe Kalahari Deposits is an Early Cretaceous (Aptian) geologic formation in South Africa. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The depositional environment is described as a crater lake where poorly lithified, concretionary conglomerate and volcaniclastic, intraclastic, calcareous mudstone were deposited under quiet subaqueous conditions, probably a "crater-fill succession above an olivine-melilitie intrusion".
WThe Kem Kem Group is a geological group along the Algeria–Morocco border in the Kem Kem region of eastern Morocco, whose strata date back to the Late Cretaceous. Its strata are subdivided into two geological formations, the older Douira Formation and younger Gara Sbaa Formation.
WThe Ksar Metlili Formation is a geological formation in eastern High Atlas of Morocco, it is late Tithonian to Berriasian in age. It is approximately 80 metres (260 ft) thick and primarily consists of mudstone and sandstone, with thin calcareous beds. One of these calcareous beds near the middle of the sequence is an important microvertebrate locality. Subsequent to the original site, several other localities have been sampled. The depositional environment is thought to be near shore deltaic.
WThe Lapurr Sandstone, also spelled Lapur Sandstone, previously considered part of the informal "Turkana Grits", is a geological formation in Kenya. It is the oldest unit in the Turkana Basin. The strata date back to the Late Cretaceous, likely Campanian to Maastrichtian, based on palynology and the presence of dyrosaurs and mosasaurs, the upper part of the unit likely extends into the Palaeogene, based on zircon dating. It predominantly consists of fine-coarse arkosic sandstone, which has been interpreted as either been deposited in fluvial or shallow marine conditions. Dinosaur remains among other vertebrates have been recovered from it around Lokitaung Gorge, though these mostly consist of heavily abraded, isolated bones of robust morphology like sauropod limb bones and caudal vertebrae.
