Iberoccitanemys
''Iberoccitanemys'' (meaning "Iberoccitanian turtle") is an extinct genus of turtle from the Bothremydidae that is known from the Marnes d'Auzas Formation in France, and also the Sobrepena Formation and Villalba de la Sierra Formation in Spain. Discovery and naming Two species are known: ''I. convenarum'' (the type) and ''I. atlanticum'', which were both referred to other generade Lapparent de Broin, F. & Murelaga, X. (1996). Une nouvelle faune de chéloniens dans le crétacé supérieur européen. ''Comptes Rendus de l’Académie des Sciences'' 323: 729-735 before being moved to ''Iberoccitanemys''; the genus was named by Perez-Garcia, Ortega & Murelaga (2012). The type species, ''I. convenarum'', was initially placed within ''Elochelys'' as ''E. convenarum'' by Laurent, Tong & Claude (2002).Y. Laurent, H. Tong, and J. Claude. (2002).

Bothremydidae
Bothremydidae is an extinct family of side-necked turtles (Pleurodira) known from the Cretaceous and Cenozoic. They are closely related to Podocnemididae, and are amongst the most widely distributed pleurodire groups, with their fossils having been found in Africa, India, the Middle East, Europe, North America and South America. Bothremydids were aquatic turtles with a high morphological diversity, indicative of generalist, molluscivorous, and piscivorous diets. Unlike modern pleurodires, which are exclusively freshwater, bothremydids inhabited freshwater, marine and coastal settings. Their marine habits allowed bothremydids to disperse across oceanic barriers into Europe and North America during the early Late Cretaceous (Cenomanian). The youngest records of the group are indeterminate remains from Saudi Arabia and Oman, dating to the Miocene. Taxonomy The family is split into two subfamilies and a number of tribes.

Villalba De La Sierra Formation
The Villalba de la Sierra Formation is a Campanian to Maastrichtian geologic formation in Spain. Fossil dinosaur eggs have been reported from the formation, that comprises gypsiferous, grey, argillaceous mudstones and sandstones, deposited in a floodplain environmentWeishampel et al., 2004, pp.517-607 characterised by high seasonality and variability in water availability. Fossil content The formation has provided abundant titanosaurian remains, including '' Lohuecotitan'' were found in the formation.Díez Díaz et al., 2016 More than 10,000 fossil remains of various fishes, amphibians, lizards, dinosaurs ('' Ampelosaurus sp.'', '' Rhabdodon sp.''), turtles ('' Foxemys mechinorum'', '' Iberoccitanemys convenarum''), and crocodiles ('' Lohuecosuchus megadontos'', '' Agaresuchus fontisensis'', '' Musturzabalsuchus sp.'') are also known from the site, one of the richest for the Late Cretaceous in Europe.Ortega et al., 2015 See also * List of dinosaur-bearing rock formations ** L ...

Marnes D'Auzas Formation
The Marnes d’Auzas Formation (Auzas marls) is a geological Formation in southwestern France (departments of Ariège and Haute-Garonne) whose strata date back to the Late Maastrichtian. It is about 100 metres thick and consists primarily of marls with some interbeds of sandstones. It corresponds to sediments whose depositional environment evolved from the paralic domain ( coastal lagoons, tidal marsh, tidal muddy channel) at the base of the formation, towards a more continental domain (alluvial plain, fluvial channels) in its upper part. The Marnes d’Auzas Formation was deposited in the west coast of the former Ibero-Armorican Island, which included much of France and Spain. Vertebrate paleofauna * Theropods: ** Theropoda indet.

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 plates th ...

Polysternon
''Polysternon'' is a genus of turtles in the extinct family Bothremydidae. It was described by Portis in 1882, and contains the species ''P. provinciale'' (originally placed in the genus ''Pleurosternon''), which existed during the Cretaceous of what is now France; ''P. atlanticum'', which existed during the Cretaceous at Laño in what is now Spain, and a new species, ''P. isonae'', from the Late Maastrichtian of Spain. The species epithet of ''P. isonae'' refers to the municipality Isona i Conca Dellà in Catalonia, where the type specimen was discovered in the Tremp Formation.

Prehistoric Turtle Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
