Lissemys
''Lissemys'' is a genus of softshell turtles in the subfamily Cyclanorbinae of the Family (biology), family Trionychidae. The genus is indigenous to southern Asia. Species The genus ''Lissemys'' contains three extant species which are recognized as being valid. *''Lissemys ceylonensis'' – Sri Lankan flapshell turtle *''Lissemys punctata'' – Indian flapshell turtle *''Lissemys scutata'' – Burmese flapshell turtle Several Extinction, extinct fossil species have been described for this genus, such as ''Lissemys piramensis'' , from Piram Island, India, but these are largely considered Nomen dubium, ''nomen dubia''. However, the extant Indian flapshell turtle (''L. punctata'') is known from fossils from as early as the Miocene. ''Nota bene'': A Binomial nomenclature, binomial authority in parentheses indicates that the species was originally described in a genus other than ''Lissemys''.

Lissemys Punctata
The Indian flapshell turtle (''Lissemys punctata'') is a freshwater species of turtle found in South Asia. The "flap-shelled" name stems from the presence of femoral flaps located on the plastron. These flaps of skin cover the limbs when they retract into the shell. It is unclear what protection the flaps offer against Predation, predators. Indian flapshell turtles are widespread and common in the South Asian provinces. It is morphologically an evolutionary link between the softshell and hardshell aquatic turtles. Exploitation for profit and habitat change are threats to their survival. Description The carapace of ''L. punctata'' viewed from above is broadly oval in adults, but more circular in young, widest just anterior to hind limbs. The width of the disc is 77–86% of its length, the carapace is moderately arched, shell height is 35.0–40.5% of carapace length, the margin of the carapace is smooth and slightly flared posteriorly, the marginal bones are not united with the p ...

Lissemys Scutata
The Burmese flapshell turtle (''Lissemys scutata''), is a species in the family Trionychidae. The species is endemic to Asia. Taxonomy Some experts ( M.A. Smith, 1931; Mertens, L. Müller & Rust, 1934) considered ''L. scutata'' to be a subspecies of '' L. punctata'' rather than its own species. Description ''L. scutata'' has an olive-brown to brown carapace with some dark spotting (in juveniles) or reticulations (in adults), and the first peripheral is smaller than the second. The head is olive to brown with an indistinct dark stripe extending backward from each orbit and another passing backward between the orbits. Distribution and habitat ''L. scutata'' lives in the Irrawaddy and Salween rivers of Myanmar, the vicinities of Bhamo, Pathein, Chauk, Yangon, Bago, and Mawlamyine in Myanmar, northeastern Thailand, and possibly in Yunnan Province, China (Kuchling, 1995).

Cyclanorbinae
Cyclanorbinae, also known commonly as the flapshell turtles, is a subfamily of softshell turtles in the family Trionychidae. The subfamily is native to Africa and Asia. Taxonomy Morphological evidence supports Cyclanorbinae being the sister group to the Plastomeninae, an extinct subfamily of softshell turtles that inhabited North America from the Cretaceous to the Eocene. Genera The subfamily Cyclanorbinae contains the following three extant genera.Turtle Taxonomy Working Group (Rhodin, Anders G.J.; Parham, James F.; van Dijk, Peter Paul; Iverson, John B.)

Trionychidae
Trionychidae is a family of turtles, commonly known as softshell turtles or simply softshells. The family was described by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish waters. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus '' Trionyx'', but the vast majority have since been moved to other genera. Among these are the North American '' Apalone'' softshells that were placed in ''Trionyx'' until 1987. Characteristics Turtles of the family Trionychidae are called "softshell" because their carapaces lack horny scutes (scales), though the spiny softshell, '' Apalone spinifera'', does have some scale-like projections, to which its common name refers. The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle
Turtles are reptiles of the order (biology), order Testudines, characterized by a special turtle shell, shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other Amniote, amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bones deve ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nota Bene
( ; plural: ) is the Latin language, Latin phrase meaning ''note well''. In manuscripts, ''nota bene'' is abbreviated in upper-case as NB and N.B., and in lower-case as n.b. and nb; the editorial usages of ''nota bene'' and ''notate bene'' first appeared in the English writing style, English style of writing around the year 1711. In Modern English, since the 14th century, the editorial usage of ''NB'' is common to the legal writing, legal style of writing of documents to direct the reader's attention to a thematically relevant aspect of the subject that qualifies the matter being litigated, whereas in academic writing, the editorial abbreviation ''n.b.'' is a casual synonym for ''footnote''. In medieval manuscripts, the editorial marks used to draw the reader's attention to a supporting text also are called marks; however, the catalogue of medieval editorial marks does not include the NB abbreviation. The medieval equivalents to the n.b.-mark are anagrams derived from the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleobiology Database
The Paleobiology Database (PBDB) is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database originated in the NCEAS-funded Phanerozoic Marine Paleofaunal Database initiative, which operated from August 1998 through August 2000. From 2000 to 2015, PBDB received funding from the National Science Foundation. PBDB also received support form the Australian Research Council. From 2000 to 2010 it was housed at the National Center for Ecological Analysis and Synthesis, a cross-disciplinary research center within the University of California, Santa Barbara. It is currently housed at University of Wisconsin-Madison and overseen by an international committee of major data contributors. The Paleobiology Database works closely with the Neotoma Paleoecology Database, which has a similar intellectual history, but has focused on the Quaternary (with an emphasis on the late Pleistocene and Holoc ...
