Zenkerella (rodent)
''Zenkerella'' is a genus of rodent, the only member of the Family (biology), family Zenkerellidae. It was formerly classified in Anomalure, Anomaluridae until phylogenetic studies made its distinctiveness clear. While the Anomalurus of the family Anomalure, Anomaluridae has gliding membranes between its forelimb and hindlimb, the ''Zenkerella'' has no such adaptation. It is estimated from fossil records that this divergence might have occurred in the middle of the Eocene. There is a single extant, the Cameroon scaly-tail, and a single fossil representative. The fossil species ''Zenkerella wintoni'' is known from a single mandible from Nandi Hills, Kenya, Songhor, Kenya dated to the Early Miocene.

Early Miocene
The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages: the Aquitanian age, Aquitanian and Burdigalian stages. The sub-epoch lasted from 23.03 ± 0.05 annum, Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change. New mammals evolved to replace the extinct animals of the Oligocene epoch. The first members of the hyena and weasel family started to evolve to replace the extinct ''Hyaenodon'', entelodonts and bear-dogs. The chalicotheres survived the Oligocene epoch. A new genus of entelodont called ''Daeodon'' evolved in order to adapt to the new habitats and hunt the new prey animals of the Early Miocene epoch; it quickly became the top predator of North America. But it became extinct due to competition from ''Amphicyon'', a newcomer from Eurasia. ''Amphicyon'' bested ''Daeodon'' because the bear-dog's la ...

Paul Matschie
file: Paul Matschie (BerlLeben 1901-09).JPG, Paul Matschie Paul Matschie (11 August 1861, Brandenburg an der Havel – 7 March 1926, Friedenau) was a German zoologist. He studied mathematics and natural sciences at the Universities of University of Halle, Halle and University of Berlin, Berlin, afterwards working as an unpaid volunteer at the Museum für Naturkunde, Berlin Zoological Museum under Jean Cabanis (1816–1906). In 1892, he was in charge of the department of mammals at the museum, later becoming a curator (1895), and in 1902, attaining the title of professor. In 1924, he was appointed second director at the museum. During the years 1891–1893, he described 11 Species description, new species of reptiles. A species of gecko, ''Hemidactylus matschiei'' (Gustav Tornier, Tornier, 1901), is named in his honor. Matschie organized the fifth International Congress of Zoologists in Berlin and was for some years co-editor of the journal ''Natur und Haus''. Matschie's tree-k ...

Zenkerella Insignis
The Cameroon scaly-tail (''Zenkerella insignis''), also referred to as the Cameroon anomalure, flightless anomalure or flightless scaly-tail, is a rodent species endemic to West Central Africa. The scientific literature has never (or possibly only obscurely) reported observations of live individuals. The taxonomic classification of the species has been subject to recent revision. Phylogeny Previous common names for this species included ''flightless scaly-tail 'squirrel'', but this is a misnomer as anomalures are very distantly related to the true squirrels of the rodent family Sciuridae and only superficially resemble them. ''Z. insignis'' is the only extant species in the genus ''Zenkerella'' and family Zenkerellidae and is the only surviving species of a lineage that diverged from the other extant anomalures (genera '' Idiurus'' and '' Anomalurus'') ~49 million years ago (Ma). Among mammals, very few species are the sole survivors of such ancient lineages, some other examples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for 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/ricochetal (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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Anomalure
The Anomaluridae are a family of rodents found in central Africa. They are known as anomalures or scaly-tailed squirrels or African flying squirrels. The six extant species are classified into two genera. All anomalurids have membranes between their front and hind legs like those of the boreal flying squirrels, but they are not closely related to the flying squirrels that form the separate 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. Like North American flying squirrels, these species have a cartilaginous rod that aids them in maintaining the extension of the patagium when in flight; unlike flying squirrels, their cartilage originates at the elbow joint ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
