Meiolaniidae
Meiolaniidae is an extinct family of large, probably herbivorous stem-group turtles with heavily armored heads and tails known from South America and Australasia. Though once believed to be cryptodires, they are not closely related to any living species of turtle, and lie outside crown group Testudines, having diverged from them around the Middle Jurassic. They are best known from the last surviving genus, ''Meiolania'', which lived in the rain forests of Australia from the Miocene until the Pleistocene, and insular species that lived on Lord Howe Island and New Caledonia during the Pleistocene and possibly the Holocene for the latter. Meiolaniids are part of the broader grouping of Meiolaniformes, which contains more primitive turtles species lacking the distinctive morphology of meiolaniids, known from the Early Cretaceous-Paleocene of South America and Australia. A similar form is also known from the Miocene Saint Bathans fauna of New Zealand. Meiolaniids reached total len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiolania Platyceps
''Meiolania'' ("small roamer") is an extinct genus of meiolaniid stem-turtle native to Australasia from the Middle Miocene to Late Pleistocene and possibly Holocene. It is best known from fossils found on Lord Howe Island, though fossils are known from mainland Australia, New Caledonia, and possibly Vanuatu and Fiji. Taxonomy The genus was erected in 1886 based on remains found on Lord Howe Island, which Richard Owen assigned to the two species ''M. platyceps'' and ''M. minor'' (now a synonym of the former). These were the first good meiolaniid remains, and were used to show that the first known remains of a related animal, a species from Queensland now known as '' Ninjemys oweni'' (which was assigned to ''Meiolania'' until 1992), did not belong to lizards as initially thought, but to turtles. Woodward sank '' Niolamia argentina'' into ''Meiolania'', but this was not accepted by later authors. The species of the genus may be summarized as In New Caledonia, ''M. mackayi ...

Meiolaniformes
Meiolaniformes is an extinct clade of stem-group turtles, defined as all taxa more closely related to ''Meiolania'' than to Cryptodira and Pleurodira. It is known from the Early Cretaceous to the Holocene of Australia, Oceania and South America. Some Eurasian taxa have been suggested to be part of the group, but this is disputed. The oldest member of Meiolaniformes is Australian Early Cretaceous '' Otwayemys''. Taxonomy The clade as currently defined contains the following taxa: * †'' Chubutemys'' Gaffney et al. 2007 - Aptian, Cerro Barcino Formation, Argentina * †'' Otwayemys'' Gaffney et al. 1998 - Aptian, Eumeralla Formation, Australia * †'' Patagoniaemys'' Sterli and de la Fuente 2011 Upper Campanian-Lower Maastrichtian, La Colonia Formation, Argentina * †'' Peligrochelys'' Sterli and de la Fuente 2011 Danian, Salamanca Formation, Argentina * †'' Trapalcochelys'' Sterli et al. 2013 Upper Campanian, Allen Formation, Argentina * †Meiolaniidae Lydekker 1887, E ...

Niolamia
''Niolamia'' is an extinct genus of South American meiolaniid turtle. Arthur Smith Woodward classified it as being in the genus '' Meiolania'', which this genus name is an anagram of, but this was not accepted by later authors. The genus is known from the Sarmiento Formation in Argentina.''Niolamia'' at Fossilworks

Sarmiento Formation
The Sarmiento Formation (Spanish: ''Formación Sarmiento''), in older literature described as the Casamayor Formation, is a geological formation in Chubut Province, Argentina, in central Patagonia, which spans around 30 million years from the mid-Eocene to the early Miocene. It predominantly consists of pyroclastic deposits, which were deposited in a semi-arid environment. It is divided up into a number of members. The diverse fauna of the Sarmiento Formation, including a variety of birds, crocodilians, turtles and snakes, also includes many mammals such as South American native ungulates ( notoungulates, litopterns, astrapotheres) as well as armadillo Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, al ...s, and caviomorph rodents.

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special 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 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 carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat ...
