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 mamma ...

List Of Largest Extant Lizards
Currently there are about 40 extant families of Lacertilia. These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (''Rhacodactylus leachianus''), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (''Varanus komodoensis''), has a length up to 3 metres (10 ft), and a body mass of 70 kg (154 lbs). Largest extant lizards Here are the 15 largest extant lizards based on the most reliable measurements for size, including length and weight.

Leiolopisma Mauritiana - Memorial Model - Ile Aux Aigrettes
''Leiolopisma'' is a genus of skinks. Most species occur in the region of New Caledonia-New Zealand, and they are related to other genera from that general area, such as ''Emoia''; these and others form the '' Eugongylus'' group. One living and two extinct taxa represent a clade endemic to the Mascarenes.(Austin & Arnold 2006) Species *''Leiolopisma alazon'' Zug, 1985 - Lauan ground skink, Ono-i-Lau ground skink *''Leiolopisma ceciliae'' Arnold & Bour, 2008 - extinct - Réunion giant skink *''Leiolopisma fasciolare'' (Girard, 1858) *''Leiolopisma telfairii'' (Desjardin, 1831) - Round Island skink, Telfair's skink An undescribed extinct taxon from Réunion was close to ''L. mauritiana'' (Austin & Arnold 2006).

Individuals would climb on observer's legs. Efforts to maintain the species in captivity p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosasaurus Hoffmanni Life
''Mosasaurus'' (; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles. It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous. The earliest fossils of ''Mosasaurus'' known to science were found as skulls in a chalk quarry near the Dutch city of Maastricht in the late 18th century, which were initially thought to have been the bones of crocodiles or whales. One skull discovered around 1780, and which was seized by France during the French Revolutionary Wars for its scientific value, was famously nicknamed the "great animal of Maastricht". In 1808, naturalist Georges Cuvier concluded that it belonged to a giant marine lizard with similarities to monitor lizards but otherwise unlike any known living animal. This concept was revolutionary at the time and helped support the then-developing ideas of extinction. Cuvier did not designate a scienti ...

Gallotia Goliath
''Gallotia goliath'' (the Tenerife giant lizard or goliath Tenerife lizard) is an extinct giant lizard species from the island of Tenerife of the Canary Islands, Spain. This reptile lived before the arrival of humans and is believed to have grown to at least long. It was described by the German herpetologist Robert Mertens. Fossils of this lizard have been found in volcanic caves, where they often appear with those of other animals, like the Tenerife giant rat. Classification Prehistoric ''Gallotia'' remains have been assigned to the taxa ''G. maxima'' and ''G. goliath'', the former supposedly occurring only on Tenerife, the latter on several islands. It was eventually determined, however, that ''G. maxima'' is a junior synonym of ''G. goliath'', and that the latter was close to the El Hierro giant lizard (''Gallotia simonyi''); supposed ''goliath'' specimens from El Hierro, La Gomera, and La Palma (from the Cuevas de los Murciélagos) are probably just extremely lar ...

Lacertidae
The Lacertidae are the 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'', 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 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 less than 9 cm long, excluding the tail, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds ( taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachylophus Gibbonsi
''Brachylophus gibbonsi'' is an extinct species of large (~1.2 m long) iguanid lizard from Tonga in the South Pacific Ocean. Its remains have been found associated with cultural sites on Lifuka, four other islands in the Haʻapai group, and Tongatapu. It was consumed by the early Tongans and probably became extinct within a century of human colonization of the archipelago 2800 years ago. The four extant members of ''Brachylophus'' are much smaller, and are found in nearby Fiji. '' B. fasciatus'' is now present on Tonga as well, but was probably brought there from Fiji by humans about 800 years ago. ''B. gibbonsi'' is estimated to have been about 1.8 times the length of its living relatives. An even larger Fijian iguana of the genus '' Lapitiguana'' was also formerly present, and also became extinct shortly after the arrival of humans. The genus ''Brachylophus'' is thought to have reached the South Pacific by rafting on the South Equatorial Current 9000 km westward from t ...

Iguanidae
The Iguanidae is a family of lizards composed of the iguanas, chuckwallas, and their prehistoric relatives, including the widespread green iguana. Taxonomy Iguanidae is thought to be the sister group to the collared lizards (family Crotaphytidae); the two groups likely diverged during the Late Cretaceous, as that is when ''Pristiguana'' and ''Pariguana'', the two earliest fossil genera, are known from. The subfamily Iguaninae, which contains all modern genera, likely originated in the earliest Paleocene, at about 62 million years ago. The most basal extant genus, '' Dipsosaurus,'' diverged from the rest of Iguaninae during the late Eocene, about 38 million years ago, with '' Brachylophus'' following a few million years later at about 35 million years ago, presumably after its dispersal event to the Pacific. All other modern iguana genera formed in the Neogene period. A phylogenetic tree of Iguaninae is shown here: Description Iguanas and iguana-type species are divers ...

Brachylophus
The genus ''Brachylophus'' consists of four extant iguanid species native to the islands of Fiji and a giant extinct species from Tonga in the South West Pacific. One of the extant species, ''B. fasciatus'', is also present on Tonga, where it has apparently been introduced by humans. Etymology and taxonomy The name, ''Brachylophus'', is derived from two Greek words: brachys (βραχύς) meaning "short" and lophos (λόφος) meaning "crest" or "plume", denoting the short spiny crests found along the backs of these species. ''Brachylophus'' species are the most geographically isolated iguanas in the world. Their closest extant relatives (the genera ''Amblyrhynchus'', '' Conolophus'', '' Ctenosaura'', '' Cyclura'', ''Iguana'' and '' Sauromalus'') are present in primarily tropical regions of the Americas and islands in the Galápagos and Lesser and Greater Antilles. Several of these genera are adapted to xeric biomes. Phylogenetic evidence supports the ''Brachylophus'' linea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapitiguana Impensa
''Lapitiguana impensa'' is an extinct giant (1.5 m long) iguanid from Fiji. It probably became extinct following the human colonization of Fiji 3000 years ago. All extant Fijian iguanas are in the genus ''Brachylophus'', together with an extinct species from Tonga. The closest living relatives of the Polynesian iguanas are found in the Americas.
