Eusaurosphargis
''Eusaurosphargis'' is an extinct genus of a diapsid reptile, known from the Middle Triassic (Anisian and Ladinian age) Besano Formation of northern Italy and Prosanto Formation of south-eastern Switzerland. It contains a single species, ''Eusaurosphargis dalsassoi''. It was a small reptile, measuring long. Discovery The holotype of ''Eusaurosphargis dalsassoi'' (BES SC 390) is a partial skeleton of a single individual found disarticulated but in close association. BES SC 390 was collected from an oil shale at Cava di Besano of the Besano Formation (Grenzbitumenzone). These lagoonal beds are equivalent to those at Monte San Giorgio, dating to the Anisian-Ladinian boundary, probably to the latest Anisian at this location, of the early Middle Triassic, about 243 million years ago. Nicole Klein and Oliver J. Sichelschmidt (2014) described disarticulated remains they referred to ''Eusaurosphargis sp''. These remains were collected from the Dutch Winterswijk Quar ...

Saurosphargis
''Saurosphargis'' is an extinct genus of a basal marine reptile, saurosphargid, known from the Middle Triassic (Anisian age) of southwestern Poland and eastern Netherlands. It contains a single species, ''Saurosphargis volzi''. Discovery ''Saurosphargis'' is known solely from the unnumbered holotype that was housed at the Breslaw Museum, a partial postcranial skeleton that included a section of 12 incomplete back vertebrae with ribs. The specimen collected at Gogolin, Gorny Slask of Upper Silesia, Poland, from the Chorzower Schichten horizon of the Lower Muschelkalk, dating to the early Anisian stage of the early Middle Triassic, about 246 million years ago. Rieppel (1995) described an isolated vertebra MGU Wr. 3873s housed at Institute of Geological Sciences, University of Wroclaw, that is possibly referable to ''Saurosphargis'', collected from the same general location. The holotype was destroyed during World War II, and as a result many authors considered ''S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Besano Formation
The Besano Formation is a geological formation in the southern Alps of northwestern Italy and southern Switzerland. This formation, a short but fossiliferous succession of dolomite and black shale, is famous for its preservation of Middle Triassic marine life including fish and aquatic reptiles. It is exposed in the vicinity of Monte San Giorgio and is among the formations responsible for the area being designated as a UNESCO World Heritage Site. In Switzerland, it is also known as the Grenzbitumenzone. Geology General geology The Grenzbitumenzone is a relatively thin band of dark dolomite and shale, approximately 5 to 16 meters in total thickness. It extends about 10 km from east to west along the northern edge of Monte San Giorgio. In individual outcrops, the Grenzbitumenzone overlies the lower part of San Salvatore Dolomite, a thick and widespread carbonate-rich formation. The later parts of the San Salvatore Formation, exposed north of Monte San Giorgio, are partiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Triassic
In the geologic timescale, the Middle Triassic is the second of three epochs of the Triassic period or the middle of three series in which the Triassic system is divided in chronostratigraphy. The Middle Triassic spans the time between Ma and Ma (million years ago). It is preceded by the Early Triassic Epoch and followed by the Late Triassic Epoch. The Middle Triassic is divided into the Anisian and Ladinian ages or stages. Formerly the middle series in the Triassic was also known as Muschelkalk. This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe. Middle Triassic fauna Following the Permian–Triassic extinction event, the most devastating of all mass-extinctions, life recovered slowly. In the Middle Triassic, many groups of organisms reached higher diversity again, such as the marine reptiles (e.g. ichthyosaurs, sauropterygians, thallatosaurs), ray-finned fish and many invertebrate groups like ...

Museo Civico Di Storia Naturale Di Milano
The Museo Civico di Storia Naturale di Milano (Milan Natural History Museum) is a museum in Milan, Italy. It was founded in 1838 when naturalist Giuseppe de Cristoforis donated his collections to the city. Its first director was Giorgio Jan. The Museum is located within a 19th-century building in the Indro Montanelli Garden, near the historic city gate of Porta Venezia. The structure was built between 1888 and 1893 in Neo-Romanesque style with Gothic elements. The museum is divided into five different permanent sections: Mineralogy (with a large collection of minerals from all over the world); Paleontology (with several fossils of dinosaurs and other prehistoric organisms); Natural History of Man (dedicated to the origins and evolution of humans with a particular attention to the relationship of the latter with the environment); Invertebrate Zoology (dedicated to mollusks, arthropods and entomology); and Vertebrate Zoology (dedicated to vertebrates, both exotic and Europea ...

Cristiano Dal Sasso
Cristiano Dal Sasso (born 12 September 1965) is an Italian paleontologist. Biography He was born in Monza, Italy and has been working since 1991 for the Milan Natural History Museum where he is the curator of fossil reptiles and birds. He was the technical coordinator of the excavations of Besano, which brought to light the complete skeleton of a Middle Triassic marine reptile of the order of Ichthyosaurs, the ''Besanosaurus'' with embryos in the belly, published in 1996 along with Giovanni Pinna. He studied ''Scipionyx'', the first dinosaur found in Italy at Pietraroja, whose description appeared in Nature in 1998. This small theropod dinosaur, nicknamed "Ciro", generated much publicity because of the unique preservation of large areas of petrified soft tissue and internal organs such as muscles and intestines. The fossil shows many details of these, even the internal structure of some muscle and bone cells. Cristiano Dal Sasso also described ''Saltriovenator'', considered as ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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 ...

Leatherback Turtle
The leatherback sea turtle (''Dermochelys coriacea''), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to and weights of . It is the only living species in the genus ''Dermochelys'' and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Taxonomy and evolution Taxonomy ''Dermochelys coriacea'' is the only species in genus ''Dermochelys''. The genus, in turn, contains the only extant member of the family Dermochelyidae. Domenico Agostino Vandelli named the species first in 1761 as ''Testudo coriacea'' after an animal captured at Ostia and donated to the University of Padua by Pope Clement XIII. In 1816, French zoologist Henri Blainville coined the term ''Dermochelys''. The leatherback was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Name Of A Biological Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstr ...

Osteoderm
Osteoderms are bony deposits forming scales, plates, or other structures based in the dermis. Osteoderms are found in many groups of extant and extinct reptiles and amphibians, including lizards, crocodilians, frogs, temnospondyls (extinct amphibians), various groups of dinosaurs (most notably ankylosaurs and stegosaurians), phytosaurs, aetosaurs, placodonts, and hupehsuchians (marine reptiles with possible ichthyosaur affinities). Osteoderms are uncommon in mammals, although they have occurred in many xenarthrans (armadillos and the extinct glyptodonts and mylodontid and scelidotheriid ground sloths). The heavy, bony osteoderms have evolved independently in many different lineages. The armadillo osteoderm is believed to develop in subcutaneous dermal tissues. These varied structures should be thought of as anatomical analogues, not homologues, and do not necessarily indicate monophyly. The structures are however derived from scutes, common to all classes of amniotes and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
