Babibasiliscus
''Babibasiliscus'' is an extinct genus of casquehead lizard (family Corytophanidae) that lived in what is now Wyoming during the early Eocene, approximately 48 million years ago. The genus is known from a single species, ''Babibasiliscus alxi'', which was named by paleontologist Jack Conrad in 2015 on the basis of a fossilized skull from the Bridger Formation in the Green River Basin. The name ''Babibasiliscus'' comes from the Shoshoni word ''babi'', meaning "older male cousin", and ''Basiliscus'', a modern-day genus of casquehead lizards. The specimen is undeformed and nearly complete except for the tip of the snout and the top of the skull, making it unclear whether the distinctive bony crest of living corytophanids was present in prehistoric relatives like ''Babibasiliscus''. The skull is about in length and the entire body is estimated to have been about long. Bones on the right side of lower jaw of the specimen are thickened and fused together, suggesting that the jaw had br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corytophanidae
Corytophanidae is a family of iguanian lizards, also called casquehead lizards or helmeted lizards, endemic to the New World. Nine species of casquehead lizards from three genera are recognized. Geographic range Corytophanids are found from Mexico, through Central America, and as far south as Ecuador. Certain species are now extant in South Florida and are considered invasive. Description The casquehead lizards are moderately sized lizards, with laterally compressed bodies, and typically have well-developed head crests in the shape of a casque helmet. This crest is a sexually dimorphic characteristic in males of ''Basiliscus'', but is present in both sexes of ''Corytophanes'' and ''Laemanctus''.Pough et al. (2003). In past years there has been evidence of corytophanids in the Eocene of North America. The greatest percentage of omnivorous species (> 10% plant diet), over 30% in each, and the highest mean percentage of plant matter in the diet are corytophanids. Behavior In ''C ...

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 and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suzanniwana Patriciana
''Suzanniwana'' is an extinct genus of iguanian lizards that lived in western North America during the earliest Eocene, approximately 56 million years ago. Two species are known from the Bighorn Basin of Wyoming: the type species ''S. patriciana'' named in 2009, and the species ''S. revenanta'' named in 2013. ''Suzanniwana'' lived during the Paleocene–Eocene Thermal Maximum, a brief period of global warming that resulted in warmer and drier conditions in the Bighorn Basin. It likely stemmed from a lineage that had migrated into the basin from regions farther to the south, following a latitudinal band of constant climatic conditions that moved northward as the planet warmed (a phenomenon known as habitat tracking). ''Suzanniwana'' shares many skeletal features with modern casquehead lizards of the family Corytophanidae and may be a stem-corytophanid. It also closely resembles ''Geiseltaliellus ''Geiseltaliellus'' is an extinct genus of iguanian lizards that lived in what is ...

Tropiduridae
The Tropiduridae are a family of iguanid lizards."Tropiduridae". The Reptile Database. www.reptile-database.org. The family is sometimes considered a subfamily, Tropidurinae. The subfamily is native to South America, including the islands of Trinidad and the Galápagos. Commonly known as neotropical ground lizards, most are ground-dwelling animals, and the subfamily includes some lizards adapted to relatively cold climates, including those of the Andes mountains and Tierra del Fuego. Several species give birth to live young. A 2021 study described a novel escutcheon-type generation gland ('α-gland') in tropidurines, found in at least 39 species. This gland is believed to be the main potential source of semiochemicals in this group indicating its importance in chemical signalling, an essential component of the communication system of lizards. Genera The family Tropiduridae contains the following eight genera. *'' Eurolophosaurus'' *'' Microlophus'' – lava lizards and Paci ...

Phrynosomatidae
The Phrynosomatidae are a diverse family of lizards, sometimes classified as a subfamily (Phrynosomatinae), found from Panama to the extreme south of Canada. Many members of the group are adapted to life in hot, sandy deserts, although the spiny lizards prefer rocky deserts or even relatively moist forest edges, and the short-horned lizard lives in prairie or sagebrush environments. The group includes both egg-laying and viviparous species, with the latter being more common in species living at high elevations. The earliest fossil remains of this group are known from the Late Cretaceous of Mongolia and belong to the genus '' Desertiguana''. As phrynosomatids are presently known only from North America, these remains indicate that phrynosomatids likely had a wider distribution in prehistoric times. Genera The Phrynosomatidae are organised into 9 genera in this family. The earless taxa (''Cophosaurus'' and ''Holbrookia'') are sister genera. Family Phrynosomatidae * '' Callis ...

Microlophus Albemarlensis
''Microlophus albemarlensis'', the Galápagos Lava lizard, also known as the Albemarle Lava lizard, is a species of Lava lizard. It is endemic to the Galápagos Islands, where it occurs on several islands in the western archipelago: the large islands Isabela, Santa Cruz, Fernandina, Santiago and Santa Fe, as well as several smaller islands: Seymour, Baltra, Plaza Sur, Daphne Major and Rábida. It is the most widespread of the Galápagos species of ''Microlophus'', the others only occurring on single islands. Some authors however, consider populations on Santiago, Santa Cruz, and Santa Fe (and associated small islands) to be distinct species (''M. jacobi'', ''M. indefatigabilis'' and ''M. barringtonensis'', respectively). The species is commonly attributed to the genus '' Microlophus'' but has been historically placed in the genus '' Tropidurus''. Description Galapagos lava lizards are generally small, ranging from 4-7 inches long. Males are around 6-7 inches long, while ...

Liolaemidae
Liolaemidae are a family of iguanian lizards. They are traditionally included in the Iguanidae as subfamily Liolaeminae, which some more recent authors prefer to delimit in a more restricted way. A common name for this group is liolaemids. Liolaemidae are typically herbivores, who have a high diet in fruit. Because of this special diet, Liolaemidae have a larger small intestine when compared to other similar omnivorous and insectivorous lizards. The genera placed here are: * '' Ctenoblepharys'' – ''cabezona'' (one species) * ''Liolaemus ''Liolaemus'' is a genus of iguanian lizards, containing many species, all of which are endemic to South America.

Leiocephalus Carinatus
''Leiocephalus carinatus'', commonly known as the northern curly-tailed lizard or saw-scaled curlytail, is a species of lizard in the family Leiocephalidae (curly-tailed lizard). Geographic range It is native to the Bahama Islands, the Cayman Islands and Cuba. It was introduced intentionally in Palm Beach, Florida, in the 1940s in an attempt to control sugar cane pests, and is now also present in a few other parts of the state. Another introduced population inhabits Swan Islands, Honduras. Description Adults may attain a snout to vent length (SVL) of , or a total length, including the tail, of . The dorsal scales are keeled and pointed. ''L. carinatus'' resembles lizards of the genus '' Sceloporus'', but with the tail usually curled upward, especially when the lizard is in a horizontal position on rocks or on the ground. Behavior An active, robust lizard, it is mostly terrestrial and will retreat into a burrow or cavity when frightened. It prefers sunny areas with loose rubble ...

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 ...

Crotaphytidae
The Crotaphytidae, or collared lizards, are a family of desert-dwelling reptiles native to the Southwestern United States and northern Mexico. Alternatively they are recognized as a subfamily, Crotaphytinae, within the clade Pleurodonta. They are very fast-moving animals, with long limbs and tails; some species are capable of achieving bipedal running at top speed. This species is carnivorous, feeding mainly on insects and smaller lizards. The two genera contain 12 species. Technical characters *Femoral pores present *Interparietal scale small (distinctly smaller than ear opening) *Never have an enlarged middorsal scale row or fringe *Never have a divided rostral scale *No bony spines or projecting ridges on their heads *No scales projecting over their ears, and no scales forming a prominent fringe on sides of toes as in Phrynosomatidae Species Genus ''Gambelia'' ''Dahms Tierleben''. www.dahmstierleben.de/systematik/Reptilien/Squamata/Iguania/crotaphytidae.

Polychrus
''Polychrus'' is the only extant genus of polychrotid lizards in the world. Commonly called bush anoles, they are found in 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.
