Cephalomyidae
Cephalomyidae is an extinct family of caviomorph rodents from South America. The specific relationships of the family are uncertain, and affinities to both chinchilloid and cavioid rodents have been supported. Most recently, Kramarz in 2005 performed a phylogenetic analysis supporting a relationship to the Cavioidea, as represented by Eocardiidae, although more recent analyses have placed them among the chinchilloids as relatives of the giant neoepiblemid rodents. McKenna and Bell (1997) questioned the validity of the family, placing the cephalomyid genera then known in Dasyproctidae, but Kramarz (2001) subsequently reasserted the distinctiveness of cephalomyids. Fossils of the family have been found in Deseadan to Colhuehuapian Fray Bentos, Deseado, Cerro Bandera and Sarmiento Formations and the Colhué Huapí Member of Argentina and the Puca Group of Bolivia.

Sarmiento Formation
The Sarmiento Formation (Spanish: ''Formación Sarmiento''), in older literature described as the Casamayor Formation, is a geological formation in Chubut Province, Argentina, in central Patagonia, which spans around 30 million years from the mid-Eocene to the early Miocene. It predominantly consists of pyroclastic deposits, which were deposited in a semi-arid environment. It is divided up into a number of members. The diverse fauna of the Sarmiento Formation, including a variety of birds, crocodilians, turtles and snakes, also includes many mammals such as South American native ungulates (notoungulates, litopterns, astrapotheres) as well as armadillo Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, along wi ...s, and caviomorph rodents.

Colhuehuapian
The Colhuehuapian age is a period of geologic time (21.0–17.5 Ma) within the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Deseadan and precedes the Santacrucian age. Etymology The age is named after the Colhué Huapí Member of the Sarmiento Formation in the Golfo San Jorge Basin, Patagonia, Argentina Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, th ....

Cerro Bandera Formation
The Cerro Bandera Formation is a geological formation in Neuquén Province, Argentina, in northern Patagonia, which dates to the Early Miocene, around 21 to 17.5 million years ago. It predominantly consists of pyroclastic deposits, which were deposited in a semi-arid environment. It is divided up into a number of members. The diverse fauna of the Cerro Bandera Formation include a variety of turtles and birds, also includes many mammals such as South American native ungulates (notoungulates, litopterns, astrapotheres) as well as armadillos, and caviomorph rodents. Material was copied from this source, which is available under a Creative Commons Attribution 3.0 International License The Cerro Bandera Formation comprises a series of isolated outcrops that represent the relicts of an old alluvial filling developed on small local valleys. It is composed of a succession of reworked pyroclastic deposits alternating with primary pyroclastic and scant sandstone levels. These deposits wer ...

Hystricognath Rodents
The Hystricognathi are an infraorder of rodents, distinguished from other rodents by the bone structure of their skulls. The masseter medialis (a jaw muscle) passes partially through a hole below each eye socket (called the infraorbital foramen) and connects to the bone on the opposite side. This, together with their lack of an infraorbital plate and the relative size of the infraorbital foramen, distinguishes hystricognaths from other rodent groups. The 18 families within the Hystricognathi are divided into two parvorders, the Phiomorpha and the Caviomorpha. The Caviomorpha are mostly native to South America, with a few species in the Caribbean and North America, while the Phiomorpha occur in the Old World. Behavior Play behavior has been observed in seven hystricognath families. The caviomorphs chase each other, play-wrestle, and gallop. The longer-legged species chase more often than the shorter-legged species. They also rotate their heads and body muscles as a form of p ...

Neoepiblemidae
The Neoepiblemidae are an extinct family of hystricognath rodents from South America. The genera '' Dabbenea'' and '' Perumys'' are now included in ''Phoberomys''. The delineation between Neoepiblemidae and Dinomyidae has historically been unclear, with some genera (such as ''Phoberomys'' and '' Eusigmomys'') having varying taxonomic placement. A 2017 study found ''Phoberomys'' to be part of the group, while ''Eusigmomys'' was found to be part of the Dinomyidae. Fossils of the family were found in the Colhuehuapian to Huayquerian Pinturas, Sarmiento, Santa Cruz, Cerro Bandera and Ituzaingó Formations and Colhué Huapí Member of Argentina, the Solimões Formation of Brazil, the Pebas Formation of Peru and the Urumaco Formation of Venezuela. at |
Cavioidea
Caviomorpha is the rodent infraorder or parvorder that unites all New World hystricognaths. It is supported by both fossil and molecular phylogeny, molecular evidence. The Caviomorpha was for a time considered to be a separate order outside the Rodentia, but is now accepted as a genuine part of the rodents. Caviomorphs include the extinct Heptaxodontidae (giant hutias) and extant families of Abrocomidae, chinchilla rats, Capromyidae, hutias, guinea pigs and the capybara, chinchillas and viscachas, tuco-tucos, Dasyproctidae, agoutis, Cuniculidae, pacas, Dinomyidae, pacaranas, Echimyidae, spiny rats, Erethizontidae, New World porcupines, Myocastoridae, coypu and Octodontidae, octodonts (Vassallo and Antenucci, 2015). Origin The first known rodent fossils in South America are represented by the three taxa ''Cachiyacuy contamanensis'', ''C. kummeli'', and ''Canaanimys maquiensis'', as well as teeth from ''Eobranisamys'' sp. (Dasyproctidae) and ''Eospina'' sp., the latter two found a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
