Juliomys Anoblepas
''Juliomys anoblepas'' is a rodent in the genus ''Juliomys'' of the subfamily Sigmodontinae known from a single broken skull. The specimen was collected by Peter Wilhelm Lund in the caves of Lagoa Santa, Minas Gerais, Brazil, in the first half of the 19th century and described by Herluf Winge in 1888 as ''Calomys anoblepas''. The species remained unstudied and its affinities unclear until 2011, when it was recognized as a member of the genus ''Juliomys'', which includes three other species from southern Brazil and nearby Argentina and Paraguay. ''J. anoblepas'' is probably a separate extinct species of the genus, which is no longer found at Lagoa Santa. ''Juliomys anoblepas'' is similar to the other members of its genus in the configuration of its zygomatic plate (a bony plate on the side of the skull). It hardly extends forward in front of the connection between the plate and the main body of the skull, and that connection is relatively low on the skull. Furthermore, the ...

Juliomys Pictipes
The lesser Wilfred's mouse (''Juliomys pictipes'') is a species of South American rodents of the family Cricetidae. It was first described by Wilfred H. Osgood under the name ''Thomasomys pictipes'', then into the genus Wilfredomys, and now known as ''Juliomys pictipes.'' The lesser Wilfred's mouse is endemic to northeastern Argentina and southeastern Brazil. Its physical appearance ranges from dark brown to light orange coloration and the typical size is small to medium. This species is arboreal, spending most of its time trees and living in the local forests at altitudes from sea level to 2000 m. Currently, this species is listed as Least Concern by the IUCN, but, threats include livestock farming, ranching, and wood harvesting. Taxonomy Juliomys pictipes was first discovered by Osgood in 1933. It was originally named ''Thomasomys pictipes''. For several decades, the placement of this species was uncertain and fairly recently changed to ''Juliomys pictipes'' to fit under ...

Juliomys Ossitenuis
''Juliomys ossitenuis'' is a species of rodent in the family Cricetidae native to South America. Taxonomy This rodent is in the Kingdom Animalia. They are found in the Phylum Chordata, Class Mammalia, and Order Rodentia. Its specific epithet is named ''Juliomys ossitenuis''. They belong to the Family Cricetidae and Subfamily Sigmodontinae. Habitat They can survive in habitats that accumulate heavy amounts of rain. Biology Three types of hair are present in the dorsal region of this species' fur: aristiform, setiform and villiform. The ventral coat is maize yellow, paws in dorsal view are light orange (apricot yellow and dark orange), tail is smooth and intensely bi-colored dorsoventrally, presence and absence of tufts of hair at the tip of the tail, and ventral coat banding pattern, with a gray base corresponding to approximately half and one third of the coat length.

Juliomys Rimofrons
''Juliomys rimofrons'', also known as the cleft-headed juliomys, is a South American rodent species in the family Cricetidae. It is found in southern Brazil. The species is arboreal and lives in montane forests. It is threatened because of the small size and fragmentation of its current range.

Wilfred Hudson Osgood
Wilfred Hudson Osgood (December 8, 1875 – June 20, 1947) was an American zoologist. Biography Osgood was born in Rochester, New Hampshire, the oldest child of a family of watchmakers. The family moved to California in 1888 and he went to study in Santa Clara, California, Santa Clara and San Jose, California, San Jose. He joined in the activities of the Cooper Ornithological Club and found company in wikisource:Author:Chester Barlow, Chester Barlow and Rollo Beck, Rollo H. Beck. He taught at a school in Arizona for a year and then moved to the newly formed Stanford University, where he came to meet Charles Henry Gilbert, Charles H. Gilbert and David Starr Jordan. He joined the staff of the Bureau of Economic Ornithology and Mammalogy, of the United States Department of Agriculture at the age of 22. This group later became the Bureau of Biological Survey under Clinton Hart Merriam. In 1909 he moved to the Field Museum of Natural History in Chicago, where he was assistant curator o ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
