Parasaurillus
''Parasaurillus'' is a genus of extinct lizard from the Early Cretaceous of southern England. The type and only species is ''Parasaurillus pseudobtusus'', named in 2002 in paleontology, 2002 by Susan E. Evans and Belinda Searle for extensive jaw and tooth material that has previously been classified as either ''Saurillus obtusus'' (from which the binomial was derived) or ''Pseudosaurillus'' from the Berriasian Lulworth Formation. The taxon was found in the Mammal Bed near the base of the formation alongside the other lizards ''Becklesius'', ''Dorsetisaurus'', ''Durotrigia'', ''Paramacellodus'', ''Pseudosaurillus'', ''Parviraptor'' and ''Saurillus obtusus''. It is likely closely related to Scincoidea, more so than other contemporary taxa. References

Pseudosaurillus
''Pseudosaurillus'' is a genus of extinct lizard from the Early Cretaceous of southern England. The type and only species is ''Pseudosaurillus becklesi'', named in 1967 by R. Hoffstetter limited jaw and tooth material from the Berriasian Lulworth Formation. A large amount of material that was additionally referred to '' Saurillus'' by Hoffstetter was reassigned to ''Pseudosaurillus'' in 1983 by Estes, but this has since been reclassified within its own genus '' Parasaurillus'' by Susan E. Evans and Belinda Searle in 2002. The taxon was found in the Mammal Bed near the base of the formation alongside the other lizards '' Becklesius'', ''Dorsetisaurus'', ''Durotrigia'', '' Paramacellodus'', ''Parasaurillus'', ''Parviraptor'' and ''Saurillus''. Like ''Becklesius'', ''Pseudosaurillus'' may be a member of the family Paramacellodidae Paramacellodidae is an extinct family of lizards that first appeared in the Middle Jurassic around 170 million years ago (Ma) and became extinct at the e ...

Purbicella
''Purbicella'' is a genus of extinct squamate from the Early Cretaceous of southern England (Lulworth Formation). The type and only species is ''Purbicella ragei'', which was described by Susan E. Evans and colleagues in 2012 for a mostly complete and articulated skull from the Berriasian Lulworth Formation of Dorset. The generic name described the region of Purbeck where the fossil was found, while the species name honours paleoherpetologist Jean-Claude Rage. ''Purbicella'' has the most complete skull of any British fossil lizard, British Geological Survey (BGS) specimen GSb581, which was originally collected prior to 1911, but then remained in BGS storage until it was rediscovered and described by Evans and colleagues. The skull is unique among coexisting taxa for having fused frontal bone The frontal bone is a bone in the human skull. The bone consists of two portions.''Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented or ...

Lulworth Formation
The Lulworth Formation is a Formation (geology), geologic formation in England. It dates from the late Tithonian to the mid Berriasian. It is a subunit of the Purbeck Group. In Dorset, it consists of three members, which are in ascending order, the Mupe Member, the Ridgway Member, and the Warbarrow Tout Member. The Mupe Member is typically 11 to 16 m thick and largely consists of marls and micrites with interbeds of calcareous mudstone. The Ridgeway Member is about 3 to 7 m thick and consists of in its western portion carbonaceous muds, marls and micrites, in the east the muds are replaced by micritic limestone. The Warbarrow Tout Member is 17 to 39 m thick and consists of limestone at the base and micrite and mudstone for the rest of the sequence, this member is the primary source of the vertebrate fossils within the formation. Elsewhere the unit is undifferentiated. Vertebrate paleobiota Amphibians Turtles Lepidosaurs Crocodyliformes Dinosaurs Mammals ...

Cordyliformes
Cordylidae is a family of small- to medium-sized lizards that occur in southern and eastern Africa. They are commonly known as girdled lizards, spinytail lizards, or girdle-tail lizards. Cordylidae is closely related to the family Gerrhosauridae, occurring in Africa and Madagascar. These two scientific families of lizards, known as Cordyliformes or Cordyloidea, are sometimes combined into a larger concept of Cordylidae. Recent molecular analyses confirm the clade made up of Cordylidae and Gerrhosauridae (Cordyloidea) and place it in a larger clade including Xantusiidae ( Cordylomorpha Vidal & Hedges, 2009).Nicolas Vidal; S. Blair HedgeThe molecular evolutionary tree of lizards, snakes, and amphisbaenians/ref> Description and behavior Girdled lizards are diurnal and insectivorous. They are terrestrial, mostly inhabiting crevices in rocky terrain, although at least one species digs burrows and another lives under exfoliating bark on trees. They have flattened heads and bodies, ...

Anguimorpha
The Anguimorpha is a suborder of squamates. The group was named by Fürbringer in 1900 to include all autarchoglossans closer to '' Varanus'' and '' Anguis'' than ''Scincus ''Scincus'' is a genus of skinks, lizards in the family Scincidae. The genus contains four or five species, all of which are typical desert inhabitants, living in sandy and dune-like areas with a hot and dry climate. Species in the genus ''Scinc ...''. These lizards, along with iguanians and snakes, constitute the proposed "venom clade" Toxicofera of all venomous reptiles. Evolution The oldest widely accepted member of Anguimorpha is ''Dorsetisaurus'' from the Late Jurassic of Europe and North America. In 2022, the genus ''Cryptovaranoides'' was described from the latest Triassic (Rhaetian) of England. ''Cryptovaranoides'' was recovered in the study as a crown-group Anguimorph, and therefore the oldest crown group-squamate, 35 million years older than any previously known crown-group squamate.

Teiidae
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: they have large rectangular scales that form distinct transverse rows ventrally and generally small granular scales dorsally, they have head scales that are separate from the skull bones, and the teiid teeth are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess well-developed limbs. Teiids are all terrestrial (few are semi-aquatic) and diurnal, and are primarily carnivor ...

Gymnophthalmidae
Gymnophthalmidae is a family of lizards with at least 250 species, sometimes known commonly as spectacled lizards or microteiids. They are called "spectacled" because of their transparent lower eyelids, which allow them to still see with closed eyes. As in most lizards, except geckos, these eyelids are movable. The Alopoglossidae have been recently moved from this family. Description and ecology Spectacled lizards are related to the Teiidae, but they look like skinks (slightly more distant relatives) with smooth scales. They are generally small lizards; many species have reduced limbs. Unusually among lizards, however, it is generally the hind limbs that are reduced or absent, rather than the forelimbs. Bauer (1998). Gymnophthalmids live in a wide variety of habitats, from desert to mountain to rain forest, throughout Central America and South America. They are usually inhabitants of the forest floor or wet areas associated with tropical forests, either nocturnal or intermitten ...

Lacertidae
The Lacertidae are the family (biology), family of the wall lizards, true lizards, or sometimes simply lacertas, which are native to Afro-Eurasia. It is a diverse family with at least 300 species in 39 genera. They represent the dominant group of reptiles found in Europe. The group includes the genus ''Lacerta (genus), Lacerta'', which contains some of the most commonly seen lizard (thus "true" lizard) species in Europe. Habitat The European and Mediterranean species of lacertids live mainly in forest and scrubland, scrub habitats. ''Eremias'' and ''Ophisops'' species replace these in the grassland and desert habitats of Asia. African species usually live in rocky, arid areas. ''Holaspis'' species are among the few arboreal lacertids, and its two species, ''Holaspis guentheri'' and ''Holaspis laevis'', are gliders (although apparently poor ones), using their broad tail and flattened body as an aerofoil. Description Lacertids are small or medium-sized lizards. Most species are le ...

Lacertoidea
The Lacertoidea is a group of squamate reptiles that includes the Lacertidae, Teiidae, Gymnophthalmidae, and Amphisbaenia. The finding from molecular phylogenetic studies that the burrowing Amphisbaenia were nested in a clade with the lizard forms led Vidal & Hedges (2005) to propose a new name for the group based on shared morphogical characters, Laterata, "referring to the presence of tile-like (squarish or quadrangular, and sometimes raised) scales that form the rings in Amphisbaenia, and are also present ventrally in Lacertiformata and Teiformata". Studies of anatomy have traditionally grouped the lacertoids with skinks; however, more recent studies focusing on DNA have placed them as a distinct group of lizards, more closely related to the venomous Toxicofera.Wiens, J. J., Hutter, C. R., Mulcahy, D. G., Noonan, B. P., Townsend, T. M., Sites, J. W., & Reeder, T. W. (2012).
