Xenosaurus
''Xenosaurus'' is a genus of lizards. ''Xenosaurus'' is the only extant genus in the family Xenosauridae with 13 species currently recognized."Xenosauridae" and "''Xenosaurus'' ". The Reptile Database. www.reptile-database.org. Also known as the Middle American knob-scaled lizards found in southwestern Tamaulipas and eastern Guerrero on the Atlantic and Pacific versants of Mexico, respectively, south and east to Alta Verapaz, Guatemala. They can be found between 300 m and 2360 m of elevation in a wide variety of habitats ranging from xerophytic tropical scrub to cloud forest to tropical rain forest. Where they occupy moderately diverse places, including crevices and holes in limestone, spaces under volcanic boulders, crevices in volcanic rocks, karst limestone, limestone terrain, and hollow logs in dry areas where trees are sparse. A flattened body shape and a crevice-dwelling ecology generally characterize species in the group. In part because of their habitat specialization, ...

Xenosaurus Grandis
''Xenosaurus grandis'', commonly known as the knob-scaled lizard, is a species of diurnal, terrestrial lizard endemic to Mexico and Guatemala. It primarily inhabits tropical rainforests. It dwells in rock crevices and eats insects. Etymology The scientific name, ''Xenosaurus grandis'', comes from the Greek words ''xenos'', meaning “alien”, “stranger”, or “foreigner”, ''saurus'', meaning “lizard”, and ''grandis'', meaning “grand” or “great”. Its common name, “knob-scaled lizard”, refers to the bumpy, “knob-like” scales found on the upper portion of its body.Gadow H (1901). ''Amphibia and Reptiles.'' London: Macmillan & Co. Taxonomy There are five recognized subspecies, which are spread throughout the species’ range, and the species complex is being reevaluated. Some of the subspecies are currently in the process of being elevated to species status. The species as a whole is listed as vulnerable by the IUCN Red List and its population is curr ...

Xenosauridae
Xenosauridae is a family of anguimorph lizards whose only living representative is the genus ''Xenosaurus'', which is native to Central America. Xenosauridae also includes the extinct genera '' Exostinus'' and '' Restes''. Also known as knob-scaled lizards, they have rounded, bumpy scales and osteoderms. Most living species prefer humid, rocky habitats, although they are widespread within their native regions, with some inhabiting semi-arid scrub environments. They are carnivorous or insectivorous, and give birth to live young. ''Shinisaurus'', the Chinese crocodile lizard, was once also regarded as a member of Xenosauridae, but most recent studies of the evolutionary relationships of anguimorphs consider ''Shinisaurus'' to be more closely related to monitor lizards and helodermatids than to ''Xenosaurus''. Xenosauridae is part of a larger clade or evolutionary grouping called Carusioidea, which, in addition to xenosaurids, includes the extinct genus ''Carusia ''Carusia'' is ...

Xenosaurus Platyceps
''Xenosaurus platyceps'', the flathead knob-scaled lizard, is a lizard found in the Sierra Madre Oriental of Mexico. Its natural habitat is dry scrub forest and oak savanna. The species is endangered due to habitat fragmentation Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes ... for the development of tourism and agriculture as well as predation by feral cats. Currently, the flathead knob-scaled lizard does not live in a protected area.Mendoza-Quijano, F. 2007. ''Xenosaurus platyceps''. In: IUCN 2012. IUCN Red List of Threatened Species. Version 2012.2. .
