Ceratodus is an extinct genus of lungfish. It has been described as a "catch all", and a "form genus" used to refer to the remains of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become extinct sometime around the beginning of the Eocene Epoch.
Comahuesuchus is an extinct genus of notosuchian crocodylomorphs from the late Cretaceous of Argentina. It was described by palaeontologist José Bonaparte in 1991. The type species is C. brachybuccalis from the Santonian Bajo de la Carpa Formation. In 2023 another species, C. bonapartei from the Sierra Barrosa Formation and Portezuelo Formation, was assigned to the genus.
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.
Toxolophosaurus was a sphenodont which lived in North America during the Early Cretaceous.
Adocus is an extinct genus of aquatic turtles belonging to the family Adocidae.
The Peedee Formation is a geologic formation in North and South Carolina. A marine deposit, named for exposures along the Great Peedee River, it preserves belemnites and foraminifera fossils dating to the Late Cretaceous (Maastrichtian). The formation is notable for its occurrence of Belemnitella americana, known as the Pee Dee Belemnite (PDB), a long-standing standard in stable carbon isotope research. A single pterosaur femur, possibly an Azhdarchid, from the Peedee formation is one of the few pterosaur body fossils found in Eastern North America.
The Prairie Bluff Chalk is a geologic formation in Alabama and Mississippi. It preserves fossils dating back to the Cretaceous period.
The Cedar District Formation is a geologic formation exposed on Vancouver Island, the Gulf Islands of British Columbia and San Juan Islands of Washington (state). It preserves fossils dating back to the Campanian Epoch of the Cretaceous period. It dates to the lower mid-Campanian.
The Deer Bay Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Cretaceous period.
The Blue Fiord Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Devonian period.
The Hecla Bay Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Devonian period.
The Stuart Bay Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Devonian period.
The Bathurst Island Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Devonian 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 Barlow Inlet Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Silurian period.
The Peel Sound Formation is a geologic formation in Nunavut. It preserves fossils dating back to the Silurian 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. With 70 cm (2.3 ft) in carapace length, Anatolemys maximus was one of the three largest macrobaenids along with Early Cretaceous Yakemys multiporcata and Paleocene Judithemys backmani.
