Pumilia
''Pumilia novaceki'' is an extinct iguanid that lived in what is now Palm Springs, California, from the Blancan to Irvingtonian stages of the Pliocene to Early Pleistocene. It is currently known from a partially crushed skull. Features of the skull show both basal iguanian features, and characters very similar to the extant ''Iguana'', suggesting that the living animal may have resembled a juvenile green iguana. Etymology The genus name, ''Pumilia'', means "diminutive" in Latin, in reference to how the living animal would have resembled a very small iguana. The specific name honors Michael J. Novacek, a colleague and friend of the describer, Mark Norell.

Iguanid
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 diverse i ...

Palm Springs
Palm Springs (Cahuilla: ''Séc-he'') is a desert resort city in Riverside County, California, United States, within the Colorado Desert's Coachella Valley. The city covers approximately , making it the largest city in Riverside County by land area. With multiple plots in checkerboard pattern, more than 10% of the city is part of the Agua Caliente Band of Cahuilla Indians reservation land and is the administrative capital of the most populated reservation in California. The population of Palm Springs was 44,575 as of the 2020 census, but because Palm Springs is a retirement location and a winter snowbird destination, the city's population triples between November and March. The city is noted for its mid-century modern architecture, design elements, arts and cultural scene, and recreational activities. History Founding Pre-colonial history The first humans to settle in the area were the Cahuilla people, who arrived 2,000 years ago.Baker, Christopher P. (2008). ...

Lapitiguana
''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.

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 the ...

Blancan
The Blancan North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 4,750,000 to 1,806,000 years Before Present, BP, a period of . Blancan North American Stage GeoWhen Database. Version 1.1.0. Retrieved 2017-June-26. It is usually considered to start in the early-mid Pliocene Epoch and end by the early Pleistocene. The Blancan is preceded by the Hemphillian and followed by the Irvingtonian NALMA stages. As usually defined, it corresponds to the mid-Zanclean through Piacenzian and Gelasian stages in Europe and Asia. In California, the Blancan roughly corresponds to the mid-Delmontian through Repettian and Venturian to the very early Wheelerian. The Austr ...

Phrynosoma Mcallii
The flat-tail horned lizard (''Phrynosoma mcallii'' ) is a species of lizard in the family Phrynosomatidae. A species of reptile, it is endemic to the Sonoran desert of the southwestern United States and northwestern Mexico. Its multiple adaptations for camouflage help to minimize its shadow. The species is threatened, with a restricted range under pressure from human activities such as agriculture and development, and is specially protected in the United States. Description and geographic range The flat-tail horned lizard is named for United States Army Colonel George A. M'Call,Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).

Early Pleistocene
The Early Pleistocene is an unofficial sub-epoch in the international geologic timescale in chronostratigraphy, being the earliest division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between 2.580 ± 0.005 Ma (million years ago) and 0.773 ± 0.005 Ma. The term Early Pleistocene applies to both the Gelasian Age (to 1.800 ± 0.005 Ma) and the Calabrian Age. While the Gelasian and the Calabrian have officially been defined by the International Union of Geological Sciences (IUGS) to effectively constitute the Early Pleistocene, the succeeding Chibanian and Tarantian ages have yet to be ratified. These proposed ages are unofficially termed the Middle Pleistocene and Late Pleistocene The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective.

Iguana
''Iguana'' (, ) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book ''Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena''. Two species are placed in the genus, the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles. Genetic analysis indicates that the green iguana may comprise a complex of multiple species, some of which have been recently described, but the Reptile Database considers all of these as subspecies of the green iguana. The word "iguana" is derived from the original Taino name for the species, ''iwana''. In addition to the two species in the genus ''Iguana'', several other related genera in the same family have common names of the species including the word "ig ...
