Scaly-tailed Squirrel
The Anomaluridae are a family of rodents found in central Africa. They are known as anomalures or scaly-tailed squirrels. The six extant species are classified into two genera. All anomalurids have membranes between their front and hind legs like those of a flying squirrel, but they are not closely related to the flying squirrels that form the tribe Petauristini of the family Sciuridae. They are distinguished by two rows of pointed, raised scales on the undersides of their tails. The anatomy of their heads is quite different from that of the sciurid flying squirrels. By extending their limbs, anomalures transform themselves into a gliding platform that they control by manipulating the membranes and tail. Most anomalurid species roost during the day in hollow trees, with up to several dozen animals per tree. They are primarily herbivorous, and may travel up to from their roosting tree in search of leaves, flowers, or fruit, although they also eat a small amount of insects. They ...

Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Kabirmys
''Kabirmys qarunensis'' is an extinct species of Anomalure, anomaluroid (scaly-tailed flying squirrel) rodent from the earliest late Eocene of the Birket Qarun Formation from northern Egypt. So far, it was monotypic in its genus. It was described in September 2010 in paleontology, 2010 by Hesham Sallam, Erik Seiffert, Elwyn Simons, and Chlöe Brindley based on isolated tooth, teeth, partial mandibles, and an edentulous partial maxilla. It is noteworthy for being the largest known Eocene anomaluroid. References Anomalures Eocene rodents Eocene mammals of Africa Fossil taxa described in 2010 {{paleo-rodent-stub ...

Long-eared Flying Mouse
The long-eared flying mouse (''Idiurus macrotis'') or long-eared scaly-tailed flying squirrel, is a species of flying mouse from western and central Africa. It is not actually a squirrel, nor a mouse, though it is a rodent. Not much is known about them because they are very hard to keep alive in captivity. To achieve gliding flight, it uses two membranes (patagia) which fold up when not in use. When the limbs are stretched wide in a star-shape, the membranes become taut and allow the rodent to glide from tree to tree. Being arboreal, ''Idiurus'' spends all of its time in the trees, living in hollow trunks in groups of 2 to 40. Limit information suggests that it is mainly frugivorous. It has a long tail in proportion to its body, sporting two lines of raised scales, and patches of scaly skin to help it grip trees, but the rest of its body is furry. The tail is longer than the body and is also used to balance, like a primate Primates are a diverse order of mammals. They ...

Dwarf Scaly-tailed Squirrel
The dwarf scaly-tailed squirrel (''Anomalurus pusillus'') is a species of rodent in the family Anomaluridae. It is found in Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon and Uganda. The species is nocturnal and arboreal and lives in subtropical or tropical lowland rainforest. Membranes attached to its limbs and tail enable it to glide between trees. This squirrel is currently not considered to be threatened by habitat destruction; "much of the habitat within parts of the known range of this species is relatively intact, and the species is unlikely to be experiencing any significant declines." Description This is a small flying squirrel, with adults having a head-and-body length of with a tail length of . This flying squirrel weighs between . The head is grey, and there is no contrasting colour on the edges of the ears. The fur on the upper parts is very variable in colour, ranging from black, grizzled gre ...

Pel's Flying Squirrel
Pel's flying squirrel or Pel's scaly-tailed squirrel (''Anomalurus pelii'') is a species of rodent in the family Anomaluridae. It is found in Liberia, Ivory Coast, and Ghana, where it lives in lowland tropical rainforests. It is named after Hendrik Pel. History The tropical forests of Africa were little explored by Europeans before the nineteenth century. Colugos and flying squirrels had been known from south eastern Asia and gliding marsupials from Australia earlier than this, but the discovery of the scaly-tailed squirrels of equatorial Africa was not made till the 1840s. British zoologist and collector Louis Fraser exploring the Niger basin brought a specimen of Lord Derby's scaly-tailed squirrel (''Anomalurus derbianus'') back to Britain. Compared to the previously known flying squirrels, this had two rows of large scales on the underside of the basal part of its tail. The flying membrane stretched from wrist to ankle and was supported by a cartilaginous strip which had it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lord Derby's Scaly-tailed Flying Squirrel
Lord Derby's scaly-tailed squirrel (''Anomalurus derbianus'') is an anomalurid rodent native to Africa. It was named after Edward Smith-Stanley, 13th Earl of Derby. Range and habitat Lord Derby's scaly-tailed squirrel lives in tropical and subtropical rainforests in western and central Africa. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Kenya, Liberia, Malawi, Mozambique, Nigeria, Sierra Leone, Tanzania, Uganda, and Zambia. Behavior Lord Derby's scaly-tailed squirrel is nocturnal, and will sleep in nests in holes in trees. They live either alone or in pairs. They move around by extending their membrane A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Membranes can be generally classified into synthetic membranes and biological membranes. ... an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australia (continent)
The continent of Australia, sometimes known in technical contexts by the names Sahul (), Australia-New Guinea, Australinea, Meganesia, or Papualand to distinguish it from the country of Australia, is located within the Southern and Eastern hemispheres. The name "Sahul" takes its name from the Sahul Shelf, which is a part of the continental shelf of the Australian continent. The continent includes mainland Australia, Tasmania, the island of New Guinea (Papua New Guinea and Indonesian Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands. Situated in the geographical region of Oceania, Australia is the smallest of the seven traditional continents. The continent includes a continental shelf overlain by shallow seas which divide it into several landmasses—the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania.
