Americobdella is a genus of carnivorous leeches from southern Chile, comprising only the species, Americobdella valdiviana.
Philippi, who originally classified A. valdiviana as an erpobdellid leech, noted that Americobdella valdiviana was similar to Trocheta (now synonymized with Erpobdella) "in both appearance and habit". [1] It is phylogenically between two major groups of leeches, the Rhynchobdellida and the Arhynchobdellida. [1] Recent work has suggested A. valdiviana is more closely related to the Erpobdelliformes than the Hirudiniformes. [1]
Americobdella valdiviana is a predator and has only rudimentary jaws. Because of these features, it was originally classified as an erpobdellid leech. [1] A. valdiviana is grey-coloured on the dorsal side with a yellowish ventral side. Whether eyes are present in this species is a matter of debate. While Philippi originally described Americobdella valdiviana as having no eyes, other authors have indicated that eyes are indeed present. [1]
A. valdiviana feeds on earthworms. [1]
Proailurus is an extinct felid genus that lived in Europe and Asia approximately 25-30.8 million years ago in the Late Oligocene and Miocene. Fossils have been found in Mongolia, Germany, and Spain.
Dalmanites is a genus of trilobite in the order Phacopida. They lived from the Late Ordovician to Middle Devonian.
Cerradomys subflavus, also known as the terraced rice rat or flavescent oryzomys, is a rodent species from South America in the genus Cerradomys. It is found in the states of Goiás, São Paulo, and Minas Gerais, Brazil. Populations in Bolivia, Paraguay, and elsewhere in Brazil that were previously placed in this species are now classified as various other species of Cerradomys.
Lithogenes is a genus of South American catfish of the family Loricariidae. It is the only genus within the subfamily Lithogeneinae.
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 lamia, also known as the buffy-sided oryzomys or monster rice rat, is a species of rodent in the family Cricetidae. It is found only in central Brazil, where it lives in forest enclaves within the cerrado. The species' known altitudinal range is from 700 to 900 m. The main threats to its survival are the destruction and fragmentation of its forest habitat.
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.
Cearachelys is an extinct genus of pleurodiran turtle which existed some 110 million years ago. The genus is monotypic, with only type species Cearachelys placidoi known.
Pratifelis is an extinct genus of feline that lived in North America during the middle Miocene period. It contains a single species, Pratifelis martini.
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.
Hylaeamys acritus, formerly Oryzomys acritus, is an oryzomyine rodent of the family Cricetidae. The name is derived from the Greek word ακριτος 'confused, doubtful', because it could easily be confused with species such as H. megacephalus and Euryoryzomys nitidus. It is known only from northeastern Bolivia; its type locality is within Noel Kempff Mercado National Park. The rodent is terrestrial and is found in moist lowland semideciduous forest and savanna. It has olive brown coloration on its back; the cheeks and flanks are amber, and the top of the head is dark. The coat is 9 mm long at the center of the torso. Chest fur between the front legs is thick and 3 to 4 mm long. Abdominal hairs are gray at the base and white at the top.
Brontotheriidae is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs. Superficially, they looked rather like rhinos with some developing bony nose horns, and were some of the earliest mammals to have evolved large body sizes of several tonnes. They lived around 56–34 million years ago, until the very close of the Eocene. Brontotheres had a Holarctic distribution, with the exception of Western Europe: they occupied North America, Asia, and Eastern Europe. They were the first fossilized mammals to be discovered west of the Mississippi, and were first discovered in South Dakota.
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.
Aiolosaurus is an extinct genus of monitor lizard from the Late Cretaceous of Mongolia. The type and only species, Aiolosaurus oriens, was named in 2000 from Ukhaa Tolgod, a rich fossil site in the Campanian-age Djadochta Formation.
Blezingeria is an extinct genus of marine reptile from the Middle Triassic of Germany. The type and only species Blezingeria ichthyospondyla was named by German paleontologist Eberhard Fraas in 1896. It is known from many isolated bones that come from a deposit in southwestern Germany called the Upper Muschelkalk, which dates back to the Ladinian stage. The relationships of Blezingeria are uncertain. Fraas identified it as a nothosaur, but it has also been classified as a cymbospondylid ichthyosaur, and most recently a thalattosaur. Many thalattosaur fossils have been found in a slightly olderLate Ladinian-age rock unit in Monte San Giorgio, Switzerland, so if Blezingeria is a thalattosaur, it may represent an early stage in an evolutionary radiation of the group across the Tethys, an ocean that covered much of what is now Europe and southern China during the Triassic. However, since Blezingeria is known from very incomplete material, its classification as a thalattosaur remains uncertain.
The Chocoan long-tongued bat is a species of bat found in South America. It was described as a new species in 2004.
Azabbaremys is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Teberemt Formation of Mali. It was described in 2001, based on a skull that had been recovered in an expedition in 1981. The genus consists solely of the type species Azabbaremys moragjonesi. The genus name is derived from Azabbar, a monster in Tamasheq folk stories. The species is named for Morag Jones, a research student who participated in the discovery of the specimen and died in the expedition. Azabbaremys is most closely related to another Paleocene side-necked turtle, Acleistochelys.
Valdiviomyia is a genus of hoverflies from the family Syrphidae, in the order Diptera.
Johnbell is an extinct genus of ungulates in the family Interatheriidae. The only known species belonging to the genus is Johnbell hatcheri. This animal was named after American paleontologist John Bell Hatcher. This genus is related to Ignigena and the subfamily Interatheriinae. This animal lived in central Chile during the Early Oligocene.
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.
