Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ...

Anomalurus Beecrofti
Beecroft's flying squirrel (''Anomalurus beecrofti'') or Beecroft's scaly-tailed squirrel, is a species of rodent in the family Anomaluridae. Some authorities consider it to be monotypic within the genus ''Anomalurops''. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and plantations. It is threatened by habitat destruction but is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Description Beecroft's flying squirrel is a medium-sized squirrel with a body-length of about with a tail of . The fur is soft and thick, the upper parts being a brindled slate-grey and the underparts being paler grey with an orangeish sheen or whitish. There is a pale spot on the crown and another on the nape of the neck. A gliding membrane extends from the fore limbs to the hind limbs and onwards to the tail. This is furred on its upper s ...

Paul Gervais
Paul Gervais full name François Louis Paul Gervais (26 September 1816 – 10 February 1879) was a French palaeontologist and entomologist. Biography Gervais was born in Paris, where he obtained the diplomas of doctor of science and of medicine, and in 1835 he began palaeontological research as assistant in the laboratory of comparative anatomy at the ''Muséum national d'Histoire naturelle''. In 1841 he obtained the chair of zoology and comparative anatomy at the Faculty of Sciences in Montpellier, of which he was in 1856 appointed dean. In 1848–1852 appeared his important work ''Zoologie et paléontologie françaises'', supplementary to the palaeontological publications of Georges Cuvier and Henri Marie Ducrotay de Blainville; of this a second and greatly improved edition was issued in 1859. In 1865 he accepted the professorship of zoology at the Sorbonne, vacant through the death of Louis Pierre Gratiolet; this post he left in 1868 for the chair of comparative anatomy at the ...

George Robert Waterhouse
George Robert Waterhouse (6 March 1810 – 21 January 1888) was an English natural history, naturalist. He was a keeper at the department of geology and later curator of the Zoological Society of London's museum. Early life George was born in Somers Town to James Edward Waterhouse and Mary Newman. His father was a solicitor's clerk and an amateur entomologist. He was the brother of Frederick George Waterhouse, who also became a zoologist. George went to school at Koekelberg, near Brussels. He returned to England in 1824 and worked as an apprentice to an architect. Part of the work was in designing the garden of Charles Knight in the Vale of Health, Hampstead and the ornamentation for St. Dunstan's Church. Natural history George became interested in entomology through his father and he founded the Entomological Society of London along with Frederick William Hope in 1833 with himself as honorary curator. He became its president in 1849–50. He wrote articles for Knight's ''P ...

Anomalurus Derbianus
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 and gliding from tree to tree. Flights of up to 250 meters (820 feet) have been recorded. They will use the scales on the bottom of their tails to help themselves climb in the trees. Lord Derby's scaly-tailed flying squirrels are mainly herbivorous, eating plant ...

Anomalurus Pelii
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 its ...

Anomalurus Pusillus
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 grey o ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...
