Scincomorpha
Scincomorpha is an infraorder and clade of lizards including skinks (Scincidae) and their close relatives. These include the living families Cordylidae (girdled lizards), Gerrhosauridae (plated lizards), and Xantusiidae (night lizards), as well as many extinct taxa. Other roughly equivalent terms include the suborder Scinciformata, or the superfamily Scincoidea, though different authors use these terms in a broader or more restricted usage relative to true skinks. They first appear in the fossil record about 170 million years ago, during the Jurassic period.Evans, S.E. and Jones, M.E.H. (2010).

Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Skink
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the red-eyed crocodile skink have a head that is very distinguished from the body. These lizards also have legs that are relatively small proportional to their body size. Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. Other gen ...

Retinosaurus
''Retinosaurus'' (meaning "amber lizard") is an extinct genus of scincomorph lizard from the Early Cretaceous of Myanmar. The genus contains a single species, ''Retinosaurus hkamtiensis'', known from a specimen preserved in amber. Discovery and naming The holotype specimen, GRS 29689, was legally obtained from a Myanmar gem dealer in 2019. It was subsequently announced in a preprint in October 2021, and validly described as a new genus and species of lizard by Čerňanský ''et al.'' in January 2022. The fossil was discovered in the Hkamti amber site of Myanmar, which dates to the early Albian, approximately 110 million years ago. The holotype, which represents a juvenile individual, includes a well-preserved articulated skull, partial postcrania, and skin impressions. In addition to the lizard fossil material, the amber also contains several coleopterans. The generic name, "''Retinosaurus''", is derived from the Greek words "retine", referring to liquid resins ...

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. The group is distinguished by having a diploglossopalatinar palate anatomy, lacking osteoderms, having conical two- or three-cusped teeth, and a unique postorbital- parietal contact. The type genus '' Globaura'' was originally classified within the now- polyphyletic group Lacertoidea, before being reclassified within its own family within Ardeosauroidea. However, '' Meyasaurus'' has also been found to be closer to Barbatteiidae Barbatteiidae is an extinct family of lizards, endemic to the paleoisland Hațeg Island in the Tethys Ocean during the final stages of the Cretaceous, In what is now Romania. It contains two monotypic genera, '' Barbatteius'' and '' Oardasaurus'' .... References {{Reflist Scincomorpha Jurassic lizards Cretaceous lizards Prehistoric reptile families ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sciroseps
''Sciroseps'' is an extinct genus of scincomorph squamates known from a partial left mandible, UA-2016-13-294, from the Early Cretaceous ( Albian) Holly Creek Formation of the Trinity Group The Trinity Group is a group (sequence of rock strata) in the Lower Cretaceous lithostratigraphy of Texas, Arkansas, Mississippi, Louisiana and Oklahoma. It is named for the Trinity River of Texas. A stratigraphic column at the Mount Bonnell Fau ... in Arkansas, USA. The type and only species is ''Sciroseps pawhuskai''. Its generic name is derived from Greek ''"σκυρος: skiros" (gypsum),'' and ''"σεπος: sepos" (lizard or snake);'' and its species name refers to historic Osage chief Pawhuska. ''Sciroseps'' is thought to be related to a clade containing the extinct Paramacellodidae and the extant Cordylidae. Suarez ''et al.'' list the defining autapomorphies for this taxon as a more gracile and convex dentary, less robust and shorter subdental laminae, dental coronae lacking li ...

Eutropis Macularia
The bronze grass skink, bronze mabuya or speckled forest skink (''Eutropis macularia''), is a species of skink found in South and Southeast Asia. It is a common, but shy, ground-dwelling species that is active both day and night. Description The bronze grass skink has a cylindrical body, dorsal scales with 5–8 keels, and smooth ventral scales. A pair of dorso-lateral bands start from above the eye and extend to the base of the tail. As with other '' Eutropis'' species, the scales are keeled. The snout is short, obtusely keeled and acuminate, and the lower eyelid is scaly. The nostril is located behind the vertical suture between the rostral scale and the first labial scale. The ear-opening is oval, about the same size as a lateral scale, or a little smaller. The dorsal, nuchal, and lateral scales have five to seven sharp keels, and there are 26 to 30 scales, approximately equal in size, round the middle of the body. The adpressed limbs meet or overlap. The digits are short an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
