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 ...

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 {{Taxonbar, from=Q96398415 Early Cretaceous life Cretaceous lizards ...

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 end of the Cretaceous around 66 Ma. It was one of the earliest groups of lizards to have undergone an evolutionary radiation, with members found across the supercontinent Laurasia. The phylogenetic relationships and constituent species of Paramacellodidae are uncertain. Many studies regard them to be scincomorphs, a large group that includes skinks and their closest extinct relatives, and possibly also to Cordyoidea, a group that includes spinytail lizards and relatives. Like modern skinks, paramacelloidids had rectangular bony plates called osteoderms covering most of their bodies, including their backs, undersides, and tails. They also had short and robust limbs. Paramacellodids are distinguished from other lizards by the combination two traits in their dentition, the teeth are labiolingually expanded at their bases, and the to ...

Durotrigia
''Durotrigia'' is a genus of extinct lizard from the Early Cretaceous of southern England. The type and only species is ''Durotrigia triconidens'', named in 1967 by R. Hoffstetter for jaw material in a review of the lizard fauna of the Berriasian Lulworth Formation. The genus was found in the Mammal Bed near the base of the formation alongside the other lizards '' Paramacellodus'', '' Becklesius'', '' Pseudosaurillus'', ''Dorsetisaurus'', '' Saurillus'' and ''Parviraptor''. ''Durotrigia'' is likely a genus within the family Globauridae Globauridae is a family of extinct scincomorph lizards that first appeared in the Late Jurassic of England and persisting until the Late Cretaceous of Mongolia.

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 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
