Trionyx
''Trionyx'' is a genus of softshell turtles belonging to the family Trionychidae. In the past many species in the family were classified in this genus, but today '' T. triunguis'', the African or Nile softshell turtle, is the only extant softshell still classified as ''Trionyx''. The other species still assigned to this genus are only known from fossils. ''T. triunguis'' is a relatively large, aquatic piscivore. Species The list of species follows a 2017 review of the Trionychidae by Georgios L. Georgalis and Walter G.

African Softshell Turtle
The African softshell turtle, or Nile softshell turtle (''Trionyx triunguis''), is a large species of softshell turtle from freshwater and brackish-water habitats in Africa (larger parts of Eastern, Northeastern, Western and Middle Africa) and the Near East (Israel, Lebanon, Syria and Turkey). It is the only extant species in the genus ''Trionyx''; historically, despite other species having been formerly placed in this genus as well, they have all been reclassified to other genera. Despite the common name of "African softshell turtle", ''Trionyx triunguis'' is not the sole species (or genus) of softshell turtle found in Africa—the genera '' Cyclanorbis'' and ''Cycloderma'' are African—nor is it solely found on that continent, alone. Description ''T. triunguis'' is a very large species of softshell turtle, with sizes ranging from 85 to 94 cm, with a weight of 40 kg, and an unconfirmed max size of 120 cm. They are omnivorous in their diet, consuming not only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Softshell Turtle
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] |
"Trionyx" Singularis
"''Trionyx''" ''singularis'' is an extinct species of prehistoric softshell turtle that inhabited freshwater habitats in interior western North America during the Early Paleocene. It is known from the Nacimiento Formation & Denver Formation of New Mexico & Colorado, USA. It lived during the Puercan (66 to 63.3 million years ago) faunal stage, only shortly after the Cretaceous-Paleogene extinction event. It is one of a number of fossil softshell turtle species that is tentatively classified to the former wastebasket taxon genus ''Trionyx''. It was initially described as '' Aspideretes singularis'', and has also been previously placed in the genus ''Palaeotrionyx'', but is presently just placed as "''Trionyx''". Remains are common in the San Juan Basin of New Mexico, and have previously been assigned to a number A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be repr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle Genera
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 ...

Miocene
The Miocene ( ) is the first epoch (geology), 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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
