Mosasaurs of Africa

Mosasaurus (; "lizard of the Meuse River") is the type genus (defining example) of the Mosasauridae, an extinct group of aquatic squamate reptiles. It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous. The genus was one of the first Mesozoic marine reptiles known to science—the first fossils of Mosasaurus were found as skulls in a chalk quarry near the Dutch city of Maastricht in the late 18th century, and were initially thought to be crocodiles or whales. One skull discovered around 1780 was famously nicknamed the "great animal of

Prognathodon is an extinct genus of marine lizard belonging to the mosasaur family. It is classified as part of the Mosasaurinae subfamily, alongside genera like Mosasaurus and Clidastes. Prognathodon has been recovered from deposits ranging in age from the Campanian to the Maastrichtian in the Middle East, Europe, New Zealand, Africa and North America.

Globidens ("Globe tooth") is an extinct genus of mosasaurid oceanic lizard classified as part of the Globidensini tribe in the Mosasaurinae subfamily. Globidens belongs to the family Mosasauridae, which consists of several genera of predatory marine lizards of various sizes that were prevalent during the Late Cretaceous. Specimens of Globidens have been discovered in Angola, Brazil, Colombia, Morocco, Syria and the United States. Among mosasaurs, Globidens is probably most well known for the highly rounded, globe-like teeth that give it its name.

Goronyosaurus is an extinct genus of marine lizard belonging to the mosasaur family. Fossils of Goronyosaurus are exclusively known from the Late Maastrichtian of the Iullemmeden Basin in West Africa, specifically the Dukamaje Formation of Niger and Nigeria and Farin Doutchi Formation of Niger. The type specimen was first described in 1930 as Mosasaurus nigeriensis, but subsequent remains revealed a highly unique set of adaptations that prompted the species to be reclassified as the only species of the new genus Goronyosaurus in 1972. These unique adaptations have made Goronyosaurus notoriousl

Tethysaurus is an extinct genus of tethysaurine mosasauroid from the Early Turonian (Late Cretaceous) period. The only species is Tethysaurus nopcsai.

Pluridens ("many teeth") is an extinct genus of marine lizard belonging to the Mosasauridae. Pluridens is placed in the subfamily Halisaurinae with the genera Phosphorosaurus, Eonatator and Halisaurus. Compared to related halisaurines, Pluridens had longer jaws with more teeth, and smaller eyes. It also grew large size, measuring long and perhaps over in some individuals. The jaws in some specimens are robust, and sometimes show injuries suggestive of combat. The jaws may have been used for fighting over mates or territories.

Igdamanosaurus, meaning "lizard from Igdaman", is an extinct genus of Cretaceous marine lizard belonging to the mosasaur family. It is classified as part of the Globidensini tribe (within the Mosasaurinae), and is like the other members of the tribe recognised by its rounded and knob-like teeth. These teeth indicate a highly specialized lifestyle, likely including a durophagous diet.

Angolasaurus ("Angola lizard") is an extinct genus of mosasaur. Definite remains from this genus have been recovered from the Turonian and Coniacian of Angola, and possibly the Coniacian of the United States, the Turonian of Brazil, and the Maastrichtian of Niger. While at one point considered a species of Platecarpus, recent phylogenetic analyses have placed it between the (then) plioplatecarpines Ectenosaurus and Selmasaurus, maintaining a basal position within the plioplatecarpinae.

Xenodens (from Greek and Latin for "strange tooth") is an extinct genus of mosasaurine mosasaurid known from the Late Cretaceous (Maastrichtian age) phosphate deposits in the Ouled Abdoun Basin of Morocco. The genus contains a single species, Xenodens calminechari, known from two isolated maxillae (upper jaw bones) with unusual saw-like teeth. While some researchers have expressed uncertainty regarding the authenticity of the holotype specimen, additional remains and CT scans have supported the original identifications.

Eremiasaurus ("desert lizard") is a genus of mosasaurs, an extinct group of marine reptiles, who lived during the Maastrichtian stage of the Late Cretaceous. The first known fossils of this taxon were teeth discovered in the Ouled Abdoun Basin in Morocco, and described in 1952 by Camille Arambourg as coming from Mosasaurus. However, it was in 2012 that Aaron R. H. LeBlanc and his colleagues described the only known species, E. heterodontus, from two more or less complete skeletons that had been discovered in the same geological area as the teeth originally described by Arambourg. Subsequently,

Gavialimimus is an extinct genus of plioplatecarpine mosasaur from the Maastrichtian of Morocco and possibly Angola.

Khinjaria (meaning "dagger") is an extinct genus of plioplatecarpine mosasaurid from the Late Cretaceous Ouled Abdoun Basin of Morocco. The genus contains a single species, K. acuta, known from a partial skull and vertebra. Khinjaria was likely an apex predator in its environment, as its large body size, blade-like teeth, and unusual skull morphology would have allowed it to attack large prey animals.
