Atokasaurus is an extinct genus of scincomorph lizard from the Early Cretaceous of Oklahoma. The type and only species is Atokasaurus metarsiodon, named in 2002 on the basis of a single isolated lower jaw bone found within the Antlers Formation in Atoka County. It is similar in appearance to extinct lizards in the family Paramacellodidae and may itself be a paramacellodid, although the phylogenetic relationships of the group are uncertain. Atokasaurus differs from other paramacellodids in having teeth in the lower jaw with enlarged bases and an S-shaped profile when viewed edge-on.


Bicuspidon is an extinct genus of Polyglyphanodontid lizard known from the Late Cretaceous of North America, Europe and Africa, two species, B. numerosus and B. smikros are known from the Cenomanian of Utah in the Mussentuchit Member of the Cedar Mountain Formation and the Naturita Formation respectively. While B. hatzegiensis is known from the Maastrichtian Sânpetru Formation of Romania and B. hogreli is known from the Cenomanian Kem Kem Beds of Morocco. An indeterminate taxon closely related to B. hatzegiensis referred to as B. aff. hatzegiensis is known from the Santonian Csehbánya Formation of Hungary. The dentition is heterodont, with conical anterior teeth and transversely orientated biscuspid posterior teeth.


Calanguban is an extinct genus of scincomorph lizard from the Early Cretaceous of South America. The type species Calanguban alamoi was named in 2014 from the Crato Formation of Brazil and is the oldest known non-iguanian lizard from the continent. It likely had an arboreal lifestyle.


Chromatogenys is an extinct genus of Scincomorph lizard from the Santonian of Hungary, containing the species C. tiliquoides. It is known from the Csehbánya Formation with the remains consisting of a partial right mandible, the name coming from the vibrant colours on the preserved specimen. The dentition is durophagous, and the animal likely ate hard shelled prey.


The Gerrhosauridae are a family of lizards native to Africa and Madagascar.


Gilmoreteius is an extinct genus of lizard from the Late Cretaceous period in Mongolia.


Jucaraseps is an extinct genus of small squamate lizard known from the Early Cretaceous of Las Hoyas, Spain. It contains a single species, Jucaraseps grandipes. It belonged to the clade Scincogekkonomorpha (containing scleroglossan squamates and those taxa which were more closely related to them than to Iguania) and was related to the clade Scleroglossa as well to Jurassic and Cretaceous taxa Eichstaettisaurus, Ardeosaurus, Bavarisaurus, Parviraptor, Yabeinosaurus and Sakurasaurus


Kleskunsaurus is an extinct genus of scincomorph lizard from the Late Cretaceous of Alberta, Canada. It was first named by paleontologists Randall L. Nydam, Michael W. Caldwell, and Federico Fanti in 2010, and the type species is Kleskunsaurus grandeprairiensis. The genus is named after Kleskun Hill Park, located east of Grande Prairie in Peace River Country. Fossils have been found from the park in a bentonitic paleosol that is part of the Campanian Wapiti Formation.

Night lizard

Night lizards (family Xantusiidae) are a group of small scincomorph lizards, averaging from less than 4 cm to over 12 cm snout-vent length. Most species are viviparous (live-bearing), with the exception of those in the genus Cricosaura. The family has only three living genera, with approximately 34 living species. The genera are divided by geographic range: Xantusia in southwestern North America and Baja California, Cricosaura in Cuba, and Lepidophyma, the most populous night lizard genus, in Central America. Three fossil genera are also known: Catactegenys, Palepidophyma, Palaeoxantusia.


Pachygenys ("thick jaw") is a genus of scincomorphan lepidosaur from the Lower Cretaceous of Japan. Its name is composed of the Greek words παχυς pachys ("thick") and γένυς génys ("jaw").


Palaeosaniwa canadensis is an extinct species of carnivorous lizard from the late Cretaceous of North America. The name, given by Charles Whitney Gilmore in 1928, means "ancient Saniwa from Canada".


Polyglyphanodon is an extinct genus of Polyglyphanodontid lizard containing the species P. sternbergi from the Maastrichtian aged North Horn Formation of Utah. The species is known from several mostly complete and partial skeletons. It is distinguished by its transversely orientated interlocking teeth, which suggest a herbivorous diet


Pseudocordylus is a genus of small to large girdled lizards from South Africa, commonly known as crag lizards. Six species of Pseudocordylus are known; they are distinguished from girdled lizards of the genus Cordylus by the presence of granular scales on the back instead of osteoderms. However, recent molecular data places Pseudocordylus within Cordylus.[1]


Ptilotodon is an extinct genus of teiid lizard from the Early Cretaceous of Oklahoma. The type and only known species is Ptilotodon wilsoni, named in 2002 on the basis of a single lower jaw with four teeth found in the Antlers Formation. The small size of the specimen may be an indication that it belonged to a juvenile.


Saurillodon was a genus of prehistoric lizard of the Late Jurassic of Portugal, UK and Morrison Formation of Western North America.Present in stratigraphic zone 4.


Skinks are lizards belonging to the family Scincidae and the infraorder Scincomorpha. With more than 1,500 described species, the Scincidae are one of the most diverse families of lizards. Common skinks include many different kinds such as the slender skink, snake-eyed skink and the skinks of Plestiodon are among the common skinks.


Squamata is the largest order of reptiles, comprising lizards, snakes and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,000 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish, and roughly equal in number to the Saurischia (one of the two major groups of dinosaurs). Members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making it possible to move the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the 16 mm (0.63 in) dwarf gecko (Sphaerodactylus ariasae) to the 5.21 m (17.1 ft) green anaconda (Eunectes murinus) and the now-extinct mosasaurs, which reached lengths of over 14 m (46 ft).

Among other reptiles, squamates are most closely related to the tuatara, which superficially resembles lizards.
