Madtsoia is an extinct genus of madtsoiid snakes. It is known from the Eocene of Argentina, the Paleocene of Brazil, the Late Cretaceous (Campanian) of Spain, the Late Cretaceous of India, and the Late Cretaceous (Maastrichtian) of Madagascar and the Coniacian of Niger. Recovered vertebrae of M. pisdurensis are 1.83 centimetres (0.72 in) long and 4.35 centimetres (1.71 in) tall) and pertain to a snake that was approximately 5 metres (16 ft) long.
Ctenochelys is an extinct genus of marine turtle, which existed during the Cretaceous period, and lived in the shallow waters of the Western Interior Seaway. Its fossils have been found in the Ripley Formation and Mooreville Chalk of central Alabama, United States. It was first named by C.H. Sternberg in 1904, and contains two species, C. stenoporus and C. acris.
Hamadasuchus is an extinct genus of sebecian crocodylomorph. Fossils have been found from the Kem Kem Formation outcropping in southeastern Morocco. These beds date back to the Albian and Cenomanian stages of the Late Cretaceous. It was first assigned to the family Trematochampsidae. Diagnostic features of the genus include its lateromedially compressed and serrated teeth. It was deep-snouted and had a slightly heterodont dentition with three distinct tooth morphologies present from sections of the lower jaw.
Microsuchus is an extinct genus of mesoeucrocodylians, belonging to Notosuchia. Fossils have been found in the Bajo de la Carpa Formation, dating to the Santonian stage of the Late Cretaceous.
Paralligator is an extinct genus of neosuchian crocodile that lived during the Late Cretaceous (Cenomanian-Maastrichtian) period in what is now the Bayan Shireh and Nemegt formations of Mongolia, approximately 96 million to 70 million years ago.
Toxolophosaurus was a sphenodont from the Early Cretaceous-age Kootenai Formation of Montana.
The Owl Creek Formation is a geologic formation ranging from Tennessee to Mississippi. It preserves fossils dating back to the Cretaceous period. Ornithomimids and ceratopsid remains are known from the formation. The ceratopsid tooth could represent a chasmosaurine.
The Tuscaloosa Formation is a geologic formation in Alabama. It preserves fossils dating back to the Cretaceous period.
The Benton Shale is a geologic formation in Montana, Wyoming, North Dakota, South Dakota, Colorado, Kansas, and Nebraska. It preserves fossils dating to the Cretaceous Period. The term Benton Limestone has also been used to refer to the chalky portions of the strata, especially the upper beds of the strata presently classified as Greenhorn Limestone. The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.
The Rosario Group is a Late Cretaceous geologic group in southwestern California and northwestern Baja California (Mexico). In older literature it was named Rosario Formation.
The Deer Bay Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Cretaceous period.

The Trold Fiord Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Permian period.
The Van Hauen Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Permian period.
The Leopold Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Silurian period.
The Blind Fiord Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Triassic period.
Anatolemys is an extinct turtle genus in the family Macrobaenidae. Two species are known, both of which lived in the Late Cretaceous. Fossils were discovered in the Yalovach Formation of Tajikistan, the Kulbikin Member and Khodzhakul and Bissekty Formations of Uzbekistan and the Bostobe Formation of Kazakhstan.
