Baiyankamys
'' Baiyankamys'' is a genus of amphibious murid rodents. It was originally described, along with the species '' Baiyankamys shawmayeri'' by Hinton in 1943 after he found the remains of a single individual in south east of the Bismarck Mountain Range, north east New Guinea. Tate, in 1951 and, Laurie and Hill in 1954, confirmed the existence of both the species and genus. Classification Hinton described '' Baiyankamys'' as similar in appearance to the species '' Hydromys habbema'' but differed due to its unreduced pinnae and its lower teeth. It was described as having three lower molars on both sides of the lower jaw, whereas other genera of amphibious murines in New Guinea have only two. In 1968 Mahoney discovered that the specimen of ''B. shawmayeri'' was a composite resulting from an incorrectly associated mandible of the species '' Rattus niobe'' and the skull of a small water rat. When the correct mandible was found in the BMNH collections Mahoney proposed that, base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydromys
''Hydromys'' is a genus (biology), genus of semiaquatic rodents in the subfamily Murinae. Three species are endemism, endemic to New Guinea and nearby islands. The fourth species, the rakali, is also found on Australia. The most recently discovered member of this genus was described in 2005. List of species Genus ''Hydromys'' - water rats: *Rakali, ''Hydromys chrysogaster'' E. Geoffroy, 1804 *Western water rat, ''Hydromys hussoni'' Musser and Piik, 1982 *New Britain water rat, ''Hydromys neobritannicus'' Tate and Archbold, 1935 *Ziegler's water rat, ''Hydromys ziegleri'' Helgen, 2005 Note: ''Hydromys habbema'' Tate and Archbold, 1941 and ''Hydromys shawmayeri'' (Hinton, 1943) are placed within ''Baiyankamys'' after Helgen, 2005.

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 ...

British Museum Of Natural History
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum (London), Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in Taxonomy (biology), taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the ...

Incisors
Incisors (from Latin ''incidere'', "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos, anteaters and other animals in the order Edentata have none. Structure Adult humans normally have eight incisors, two of each type. The types of incisors are: * maxillary central incisor (upper jaw, closest to the center of the lips) * maxillary lateral incisor (upper jaw, beside the maxillary central incisor) * mandibular central incisor (lower jaw, closest to the center of the lips) * mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in permanent teeth. Young children may have from zero to eight incisors depending on the stage of their tooth eruption and Human tooth development, tooth d ...
