Sibirotitan
''Sibirotitan'' ("Siberian titan") is a genus of somphospondyl sauropod from the Ilek Formation of Russia. The type and only species is ''S. astrosacralis''. Discovery and naming The material assigned to ''Sibirotitan'' was found in the Shestakovo 1 locality of the Ilek Formation, deposited in a cliff on the Kiya River's right bank, near Shestakovo Village in Kemerovo Province, West Siberia, Russia. Vertebrate remains were first recovered in 1953, and larger dinosaur fossils were found later in the sixties. Definitive sauropod remains were first discovered during expeditions in 1994 and 1995. In 2002, a reasonably complete foot would be described by Russian vertebrate paleontologist Alexander Averianov and colleagues; there was insufficient material to name the taxon, but they identified it as a member of Titanosauriformes, noting teeth from the locality indicated possible brachiosaur identity, but that a caudal vertebra from a nearby locality indicated the presence of a ...

Ilek Formation
The Ilek Formation is a Lower Cretaceous geologic formation in Western Siberia. Many different fossils have been recovered from the formation. It overlies the Late Jurassic Tyazhin Formation and underlies the Albian Kiya Formation. The formation was described by L. A. Ragozin in 1935. It consists of sands with sandstone concretions, layers of silts, clays and marls. Age of the formation, according to a crude 1962 estimate, is Valanginian(?) - Hauterivian - Barremian. Its thickness varies greatly, reaching 746 m in Teguldet borehole. Fauna A fragmentary wing metatarsal nearly identical to the pterosaur ''Lonchognathosaurus'' is also known.

Somphospondyli
Somphospondyli is an extinct clade of titanosauriform sauropods that lived from the Late Jurassic until the end of the Late Cretaceous, comprising all titanosauriforms more closely related to Titanosauria proper than Brachiosauridae. The remains of somphospondylans have been discovered in all six continents. Classification The group has officially been defined under the PhyloCode as the largest clade containing ''Saltasaurus loricatus'', but not ''Giraffatitan brancai.'' Features found as diagnostic of this clade by Mannion ''et al.'' (2013) include the possession of at least 15 cervical vertebrae; a bevelled radius bone end; sacral vertebrae with camellate internal texture; convex posterior articular surfaces of middle to posterior caudal vertebrae; biconvex distal caudal vertebrae; humerus anterolateral corner "squared"; among multiple others. The following cladogram depicts the reference phylogeny used to defined Somphospondlyi under the PhyloCode The ''International Code ...

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''. Regional equivalents The Barremian falls in the Gallic epoch, a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fukuititan
''Fukuititan'' (meaning "Fukui giant") is a genus of titanosauriform sauropod dinosaur that lived in the Early Cretaceous (either Barremian or Aptian age) in what is now Japan. It is known from FPDM-V8468, the associated partial skeleton of a single individual, recovered from the Kitadani Dinosaur Quarry (Kitadani Formation) of the Tetori Group, at Katsuyama City. The type species, ''Fukuititan nipponensis'', was described in 2010 by Japanese scientists Yoichi Azuma and Masateru Shibata of the Fukui Prefectural Dinosaur Museum The , located in Katsuyama, Fukui, Japan, is one of the leading dinosaur museums in Asia that is renowned for its exhibits of fossil specimens of dinosaurs and paleontological research.

Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22.

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Arkharavia
''Arkharavia'' (meaning "Arkhara road") is a dubious genus of somphospondylan sauropod, but at least some of the remains probably belong to a hadrosaurid. It lived in what is now Russia, during the Late Cretaceous. It was described in 2010 by Alifanov and Bolotsky. The type species is ''A. heterocoelica''. Description The holotype material consists of a single anterior caudal vertebra. Also, a tooth and a few proximal tail vertebrae (from near the base of the tail) were originally described as belonging to this species, but these probably belong to an indeterminate hadrosaur. The vertebrae are unusual in being weakly heterocoelous, which means that the centrum or body of a vertebra has saddle-shaped surfaces where it meets the vertebrae in front or behind it. Classification ''Arkharavia'' was originally classified as a titanosauriform sauropod, thought to be related to '' Chubutisaurus'', a sauropod from the Cretaceous of Argentina. However, further study showed that the refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Twelve Olympians
upright=1.8, Fragment of a relief (1st century BC1st century AD) depicting the twelve Olympians carrying their attributes in procession; from left to right: Hestia (scepter), Hermes (winged cap and staff), Aphrodite (veiled), Ares (helmet and spear), Demeter (scepter and wheat sheaf), Hephaestus (staff), Hera (scepter), Poseidon (trident), Athena (owl and helmet), Zeus (thunderbolt and staff), Artemis (bow and quiver) and Apollo (lyre) from the Walters Art Museum. In ancient Greek religion and Greek mythology, mythology, the twelve Olympians are the major Deity, deities of the Greek mythology, Greek pantheon, commonly considered to be Zeus, Hera, Poseidon, Demeter, Aphrodite, Athena, Ares, Artemis, Apollo, Hephaestus, Hermes, and either Hestia or Dionysus. They were called ''Olympians'' because, according to tradition, they resided on Mount Olympus. Although Hades was a major ancient Greek god and was the brother of the first generation of Olympians (Zeus, Poseidon, Hera, De ...
