Deinosuchus is an extinct genus of eusuchian, either an alligatoroid crocodilian or a stem-group crocodilian, which lived during the Late Cretaceous around . The first remains were discovered in North Carolina (United States) in the 1850s, and the genus was first described in 1909. Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of

Cryodrakon is a genus of azhdarchid pterosaur that lived during the late Campanian age of the Late Cretaceous period in what is now Canada, around 76.7 and 74.3 million years ago. Starting in 1972, fossil remains of large azhdarchid pterosaurs have been reported from Alberta. Paleontologists assigned them to the genus Quetzalcoatlus, given that it was the only known azhdarchid from North America back then and because they had limited information about its actual remains, so they simply could not deduce anything different. In 1992, a partial pterosaur skeleton was uncovered in the Dinosaur Park

Allodaposuchus is an extinct genus of crocodyliforms that lived in what is now southern Europe during the Campanian and Maastrichtian stages, and possibly the Santonian stage, of the Late Cretaceous. Although generally classified as a non-crocodylian eusuchian crocodylomorph, it is sometimes placed as one of the earliest true crocodylians. Allodaposuchus is one of the most common Late Cretaceous crocodylomorphs from Europe, with fossils known from Romania, Spain, and France.

Armadillosuchus is an extinct genus of sphagesaurid crocodylomorph. It was described in February 2009 from the late Campanian to early Maastrichtian Adamantina Formation of the Bauru Basin in Brazil, dating to approximately 70 Ma. Armadillosuchus was among the larger and more robust sphagesaurids, with a total length of approximately .

Deltatheridium (meaning triangle beast or delta beast) is an extinct species of metatherian. It lived in what is now Mongolia during the Upper Cretaceous, circa 80 million years ago. A study in 2022 strongly suggested that Deltatheridium was a marsupial, making it the earliest known member of this group.

Scanisaurus is a dubious genus of plesiosaur that lived in what is now Sweden and Russia during the Campanian stage of the Late Cretaceous period. The name Scanisaurus means "Skåne lizard", Skåne being the southernmost province of Sweden, where a majority of the fossils referred to the genus have been recovered. The genus contains one species, S. nazarowi, described in 1911 by Nikolay Bogolyubov as a species of Cimoliasaurus based on a single vertebral centrum discovered near Orenburg, Russia. the species was moved into its own genus by Per-Ove Persson in 1959 after several differences were ob

Ginglymostoma (from the Ancient Greek words γίγγλυμος (gínglumos), meaning "hinge", and στόμα (stóma), meaning "mouth") is a genus of shark in the family Ginglymostomatidae. There are two members in the genus. Members of this genus eat small fish and crustaceans, and are commonly quite lethargic unless provoked. Members of this genus have the ability to suck in water in order to remove snails from their shells in a manner that can be described as 'vacuum-like'.

Alexandronectes is a genus of elasmosaurid plesiosaur, a type of long-necked marine reptile, that lived in the oceans of Late Cretaceous New Zealand. It contains one species, A. zealandiensis. Fossils of Alexandronectes were found in the Conway Formation of Canterbury, which can be dated to the Early Maastrichtian stage of the Cretaceous. Fossils of it were found around 1872 near the Waipara River, north of Christchurch, New Zealand.

Uberabasuchus ("Uberaba crocodile") is an extinct genus of crocodylomorph from the Late Cretaceous Serra da Galga Formation of Brazil. It appears to have a high skull like that of the sebecosuchians, but differs from them in having teeth with circular cross-section. Thus, rather than slicing flesh and blood vessels, it is likely to have inflicted powerful crushing bites . The post-crania and the geology suggesting an arid climate indicate that Uberabasuchus was likely a terrestrial predator.

Kawanectes (meaning "Kawas swimmer") is an extinct genus of elasmosaurid plesiosaur, a type of long-necked marine reptile, that lived in the marginal marine, probably estuarine, environment of Late Cretaceous Patagonia. The genus contains a single species, Kawanectes lafquenianum, described in 2016 by José P. O'Gorman.

Ferugliotherium is a genus of fossil mammals in the family Ferugliotheriidae from the Campanian and/or Maastrichtian period (Late Cretaceous; around 70 million years ago) of Argentina. It contains a single species, Ferugliotherium windhauseni, which was first described in 1986. Although originally interpreted on the basis of a single brachydont (low-crowned) molar as a member of Multituberculata, an extinct group of small, rodent-like mammals, it was recognized as related to the hypsodont (high-crowned) Sudamericidae following the discovery of additional material in the early 1990s. After a ja

Gondwanatherium is a genus of stem-mammal from the extinct suborder Gondwanatheria that lived in Patagonia, South America during the "Age of Dinosaurs", specifically during the Late Cretaceous (Campanian to Maastrichtian epochs).

Magallanodon is a genus of large mammal from the extinct group Gondwanatheria. It contains a single species, Magallanodon baikashkenke. The species is the first Mesozoic mammal known from Chile, and is Late Cretaceous in age. It is known from individual teeth found in a quarry in the Río de Las Chinas Valley and La Anita Farm located in the Magallanes Basin in Patagonia. The fossils come from the Dorotea Formation and Chorrillo Formation, which is Late Campanian to Early Maastrichtian in age. It was more recently estimated to weigh ~10.34 kg.
