Dipsosaurus Dorsalis
The desert iguana (''Dipsosaurus dorsalis'') is an iguana species found in the Sonoran and Mojave Deserts of the Southwestern United States and northwestern Mexico, as well as on several Gulf of California islands. Taxonomy The species was first described in the ''Catalog of North American Reptiles'', by Spencer Fullerton Baird and Charles Frédéric Girard, in 1859 as ''Crotaphytus dorsalis.'' It was reclassified two years later as ''Dipsosaurus dofus dorsalis'' by Edward Hallowell. The generic name comes from a combination of two Greek words meaning "thirsty lizard": "" () for "thirsty", and "" () for "lizard". The specific name, "dorsalis", comes from the Latin word ''dorsum'' meaning "spike", in reference to a row of enlarged spiked scales on the middle of the lizard's back which form a crest that extends almost to the tip of its vent. ''Dipsosaurus'' contains two species, ''D. dorsalis'', and ''D. catalinensis''. Genetic evidence supports ''Dipsosaurus'' being the ...

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 ...

Edward Hallowell (herpetologist)
Edward Hallowell (1808 – February 20, 1860) was an American herpetologist and physician. He studied and practiced medicine in Philadelphia. He also was a renowned herpetologist who described 61 new species of reptiles. In 1851, Hallowell was elected as a member of the American Philosophical Society The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and communit .... Hallowell is commemorated in the scientific names of two species of frogs: '' Hyla hallowellii'' and '' Leptodactylus hallowelli. Cope ED (1862). "On some new and little known American ANURA".

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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 ...

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 opini ...
