Polychrotidae
The Polychrotidae family (sometimes classified as the Polychrotinae subfamily instead) of iguanian lizards contains the living genus ''Polychrus'' (commonly called bush anoles) and the extinct genus '' Afairiguana''. The family Polychrotidae was once thought to encompass all anoles, including those in the genus ''Anolis'' (which are now included in the family Dactyloidae Dactyloidae are a family of lizards commonly known as anoles () and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfami ...). Studies of the evolutionary relationships of anoles based on molecular information has shown that ''Polychrus'' is not closely related to ''Anolis'', but instead closer to Hoplocercidae. It is therefore not part of Dactyloidae and instead is treated as the family, Polychrotidae. References Extant Ypresian first appearances Lizard families Extant Eoc ...

Anole
Dactyloidae are a family of lizards commonly known as anoles () and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloidae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with '' Polychrus'' (bush anoles), but the latter genus is not closely related to the true anoles. Anoles are small to fairly large lizards, typically green or brownish, but their color varies depending on species and many can also change it. In most species at least the male has a dewlap, an often brightly colored flap of skin that extends from the throat/neck and is used in displays. Anoles share several characteristics with geckos, including details of the foot structure (for climbing) and the ability to voluntarily break off the tail (to escape predators), but they are only very distantly related, anoles being part of Iguania ...

Polychrus Acutirostris
''Polychrus acutirostris'', the Brazilian bush anole, is a species of lizard native to southern and eastern Brazil, Paraguay, Argentina, and eastern Bolivia. It is diurnal. Description ''Polychrus acutirostris'' is a medium-sized lizard. One of the lizard's predators is the curl-crested jay. The lizard is omnivorous, known for eating both insects and plant Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae excl ...s. Research have also shown that the lizards are subject to bacterial infections, but rarely parasites.

Iguania
Iguania is an infraorder of squamate reptiles that includes iguanas, chameleons, agamids, and New World lizards like anoles and phrynosomatids. Using morphological features as a guide to evolutionary relationships, the Iguania are believed to form the sister group to the remainder of the Squamata, which comprise nearly 11,000 named species, roughly 2000 of which are iguanians. However, molecular information has placed Iguania well within the Squamata as sister taxa to the Anguimorpha and closely related to snakes. The order has been under debate and revisions after being classified by Charles Lewis Camp in 1923 due to difficulties finding adequate synapomorphic morphological characteristics. Most Iguanias are arboreal but there are several terrestrial groups. They usually have primitive fleshy, non-prehensile tongues, although the tongue is highly modified in chameleons. The group has a fossil record that extends back to the Early Jurassic (the oldest known member is '' Bha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychrus
''Polychrus'' is the Monotypic taxon, only extant genus of Polychrotidae, polychrotid lizards in the world. Commonly called bush anoles, they are found in Central America, Central and South America, as well as nearby Trinidad and Tobago. ''Polychrus'' means "many colored". True anoles in other genera are now placed in Dactyloidae. ''Polychrus'' is presently in the family Polychrotidae.

Afairiguana
''Afairiguana avius'' is an extinct iguanid lizard known from a nearly complete and articulated skeleton discovered in rocks of the Early Eocene-aged Green River Formation of Wyoming, United States. As of the initial description, the skeleton represents the oldest complete iguanian from the Western Hemisphere, and is the oldest representative of the extant iguanid family of anoles, Polychrotidae. Description ''Afairiguana'' is based on FMNH PR 2379, a skeleton collected from the Warfield Springs locality of the Fossil Butte Member of the Green River Formation. It was described in 2007 by Jack Conrad, Olivier Rieppel, and Lance Grande. The type species is ''A. avius''. The genus is a combination of the Ancient Greek word for abstract () and ''iguana'', while the species name is derived from the Latin word meaning lost (''avius''), referring to the species' geographic distance from other polychrotids. FMNH PR 2379 is essentially complete, including some car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anolis
''Anolis'' is a genus of anoles (), iguanian lizards in the family Dactyloidae, native to the Americas. With more than 425 species, it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 ''Anolis'' species remain. Previously, it was classified under the family Polychrotidae that contained all the anoles, as well as '' Polychrus'', but recent studies place it in the Dactyloidae. Taxonomy This very large genus displays considerable paraphyly, but phylogenetic analysis suggests a number of subgroups or clades. Whether these clades are best recognized as subgenera within ''Anolis'' or separate genera remains a matter of dispute. If the clades are recognized as full genera, about 45 species remain in ''Anolis'', with the remaining moved to ''Audantia'' (9 species), ''Chamaelinorops'' (7 species), ''Ctenonotus'' (more than 40 species), ''Dactyloa'' (''circa'' 95 specie ...

Lizard Families
This is a list of the extant lizard families. Lizards are an informal group of squamates. Taxonomy There are five infraorders which separate the lizards, these are: Diploglossa, Gekkota, Iguania, Platynota and Scincomorpha. This separation is based mainly on morphological similarities between family groups. The Diploglossans and Platynotans are two closely related infraorders which are very diverse families. Very few generalisations can be placed upon these families morphologically. Many species are limbless, while others have fully formed limbs. It is believed that these lizards are the closest lizard relation to the snakes. The Gekkotans are the second most diverse group of lizards. They can be morphologically distinguished by the absence of temporal arches, which allows greater moveability of the head. Most species also have cloacal sacs and fixed eyelids. The Iguanians are another diverse group of lizards. All iguanians are fully limbed. Most species ambush their prey, cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific name ...
