Handleyomys alfaroi, also known as Alfaro's rice rat or Alfaro's oryzomys, is a species of rodent in the genus Handleyomys of family Cricetidae. It is found in Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. It was previously included in Oryzomys as Oryzomys alfaroi. Its natural habitats are subtropical and tropical lowland or montane dry forests at elevations ranging from sea level to 2500 m.
Oreoryzomys balneator, also known as the Peruvian rice rat or Ecuadoran oryzomys, is a species of rodent in the tribe Oryzomyini of family Cricetidae. It is found in Ecuador and northern Peru in cloud forest at elevations from 1500 to 1800 m. It is the only species in the genus Oreoryzomys, which was included in Oryzomys until 2006. The genus name Oreoryzomys is a combination of ορος the Greek word for "mountain" with the old genus name Oryzomys and refers to the mountainous habitat of O. balneator. Recent research suggests that O. balneator is not closely related to Oryzomys, but instead is probably related to Microryzomys within a clade also including Neacomys and Oligoryzomys.
Euryoryzomys legatus, also known as the Tarija oryzomys or big-headed rice rat, is a species of rodent in the family Cricetidae. It now belongs to the genus Euryoryzomys, having previously been placed in Oryzomys. It is found in the eastern Andes of northwestern Argentina and southern Bolivia.
Hylaeamys megacephalus, also known as Azara's broad-headed oryzomys or the large-headed rice rat, is a species of rodent in the genus Hylaeamys of family Cricetidae, of which it is the type species. It is found mainly in lowland tropical rainforest from its type locality in Paraguay north through central Brazil, French Guiana, Guyana, Suriname, and Venezuela onto Trinidad and Tobago. To its west and east, other closely related species of Hylaeamys are found: H. perenensis in western Amazonia, H. acritus in Bolivia, and H. laticeps and H. oniscus in the Atlantic Forest of eastern Brazil.
Handleyomys rhabdops, also known as the highland oryzomys or striped rice rat, is a species of rodent in the genus Handleyomys of family Cricetidae. It is nocturnal and is found in Guatemala and Mexico in montane forest at elevations from 1250 to 3250 m.
Handleyomys rostratus, also known as the long-nosed oryzomys, long-nosed rice rat, or rusty rice rat is a species of rodent in the genus Handleyomys of family Cricetidae. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. It is nocturnal and is found in forests at elevations above sea level to 1200 meters. The Handleyomys rostratus attains its highest level of development in south and Central America. High rates of deforestation and habitat destruction are the biggest threat to the Handleyomys rostratus.
Handleyomys saturatior, also known as the cloud forest oryzomys or cloud forest rice rat, is a species of rodent in the genus Handleyomys of family Cricetidae. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua in cloud forest at elevations from 750 to 2500 m. It was previously placed in the genus Oryzomys.
Sphaeropsocidae is a family of Psocodea, belonging to the suborder Troctomorpha. Females of this family have reduced, beetle-like elytra, and lack hindwings, with males have either small or absent wings. The family comprises 22 known species in eight genera.
Hylaeamys is a genus of South American oryzomyine rodents found principally in humid forested areas east of the Andes. The species in this genus have historically been placed in Oryzomys. They are most closely related to Euryoryzomys, Transandinomys, Nephelomys, Oecomys, and Handleyomys, and most closely resemble species of the former two genera. They are distinguished from members of Euryoryzomys by all-dark or indistinct two-tone tail coloration, from members of Transandinomys by having shorter whiskers above their eyes that do not extend posteriorly behind their ears, and in both cases by differences in carotid circulation. The genus is named after hylaea, the term used by Humboldt for the lowland South American rainforests that are the main habitat of the genus.
Handleyomys is a genus of Central and South American rodents in the tribe Oryzomyini of family Cricetidae. It was first described in 2002 to include two species from the Colombian Andes which were previously included in distinct and unrelated genera, Aepeomys and Oryzomys, but which turned out to be closely related. Later, in 2006, six other species were provisionally added from Oryzomys; these are expected to be placed in new genera in the future.
Anshunsaurus is a genus of thalattosaurs within the family Askeptosauridae. Fossils have been found from Middle Triassic deposits in Guizhou, China. Three species are known: the type species A. huangguoshuensis, the slightly older species A. wushaensis, and the species A. huangnihensis.
Abanico Formation is a 3 kilometres (9,800 ft) thick sedimentary formation exposed in the Andes of Central Chile. The formation has been deposited in a timespan from the Eocene to the Miocene. Abanico Formation's contact with the overlying Miocene Farellones Formation has been the subject of differing interpretations since the 1960s. A small part of the formation crops out in the Mendoza Province of western Argentina.
Eomakhaira is an extinct genus of thylacosmilid sparassodont known from the Oligocene Abanico Formation of Chile. It contains a single species, Eomakhaira molossus.
Eomorphippus is an extinct genus of notohippid notoungulate that lived from the Late Eocene to the Early Oligocene in what is today South America.
Ignigena is an extinct genus of notoungulate belonging to the family Interatheriidae. The only known species of this genus is Ignigena minisculus. The genus name means born from the fire, referencing the volcanic deposits in which its fossils were found, while the type species name minisculus means "minuscule", referencing the small size of the animal. It was related to Johnbell. I. minisculus was a small animal with elongated teeth. Its fossilized remains were found in Chile, in deposited dating to the Early Eocene.
Colpodon is an extinct genus of herbivorous mammal, belonging to the order Notoungulata. It lived during the Early Miocene, in what is today Argentina and Chile, in South America.
Termastherium is an extinct genus of leontiniid notoungulates that lived during the Early Oligocene of what is now Chile. Fossils of this genus have been found in the Oligocene-aged Abanico Formation of Chile.
Santiagorothia is an extinct genus of interatheriid notoungulate. It lived during the Early Oligocene, and its fossils were discovered in Argentina and Chile.
Eopachyrucos is an extinct genus of interatheriid notoungulates that lived from the Middle Eocene to the Late Oligocene of Argentina and Uruguay. Fossils of this genus have been found in the Sarmiento Formation of Argentina and the Fray Bentos Formation of Uruguay.
Rosendo is an extinct genus of notohippid notoungulates that lived during the Early Oligocene in what is now Argentina and Chile. Fossils of this genus have been found in the Sarmiento Formation and the Abanico Formations of Argentina and Chile.
