Woolungasaurus Glendowerensis
''Woolungasaurus'' ('Woolunga lizard', named after an Aboriginal mythical reptile, Persson 1960) is a dubious genus of plesiosaur, an extinct marine reptile, belonging to the Elasmosauridae. History The type species, ''Woolungasaurus glendowerensis'', was named after Glendower Station by Per Ove Persson in 1960,Persson, P.O., 1960, "Lower Cretaceous Plesiosaurians (Reptilia) from Australia", ''Lunds Universitets Arsskrift'' 56(12): 1-23 is known from a partial skeleton, holotype QM F6890, (forty-six vertebrae, ribs, forearms, shoulder girdle and part of the rear limbs) unearthed from the Wallumbilla Formation (Albian, Lower Cretaceous) of the Richmond District, Queensland, Australia. Another find of undetermined species, consisting of twelve vertebrae, was unearthed from the Maree Formation (Cretaceous, of uncertain age) of Neales River, near Lake Eyre, South Australia.

Early Cretaceous
The Early Cretaceous (geochronology, geochronological name) or the Lower Cretaceous (chronostratigraphy, chronostratigraphic name) is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 143.1 Megaannum#SI prefix multipliers, Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian–Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining Anoxic event#Cretaceous, early Aptian Oceanic Anoxic Event 1a (OAE1a) was dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java Plateau, Ontong Java-Manihiki Plateau, Manihiki-Hikurangi Plateau, Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history.

Fossil Taxa Described In 1960
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Plesiosaurs Of Oceania
The Plesiosauria or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous ''Plesiosaurus'', was named in 1821. Since then, more than a hundred valid species have been described. In the early twenty-first century, the number of discoveries has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Timeline Of Plesiosaur Research
This timeline of plesiosaur research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, Taxonomy (biology), taxonomic revisions, and cultural portrayals of plesiosaurs, an order of marine reptiles that flourished during the Mesozoic Era. The first scientifically documented plesiosaur fossils were discovered during the early :19th century in paleontology, 19th century by Mary Anning. Plesiosaurs were actually discovered and described before dinosaurs. They were also among the first animals to be featured in Paleoart, artistic reconstructions of the ancient world, and therefore among the earliest prehistoric creatures to attract the attention of the lay public. Plesiosaurs were originally thought to be a kind of primitive transitional form between marine life and terrestrial reptiles. However, now plesiosaurs are recognized as highly derived marine reptiles descended from terrestrial ancestors. Early researchers thought that plesiosau ...

List Of Plesiosaur Genera
This list of plesiosaurs is a comprehensive listing of all genera that have ever been included in the order Plesiosauria, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomen dubium''), or were not formally published (''nomen nudum''), as well as junior synonyms of more established names, and genera that are no longer considered plesiosaurs. The list currently includes genera. Scope and terminology There is no official, canonical list of plesiosaur genera but one of the most thorough attempts can be found on the Plesiosauria section of Mikko Haaramo's Phylogeny Archive; also pertinent is the Plesiosaur Genera section at Adam Stuart Smith's Plesiosaur Directory.See Smith, ''Plesiosaur Genera''. Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously ...

Sven Sachs
Sven is a Scandinavian masculine first name. In Old Norse the meaning was "young man" or "servant" and the original Old Norse spelling was ''sveinn''. Variants such as '' Svend'' are found in Danish and Norwegian. Another variant, ''Svein'' is used only in the Low Countries and German-speaking countries, and is cognate with the English surname '' Swain''. In medieval Swedish, ''sven'' or ''sven av vapen'' "sven of arms", is a term for squire. The female equivalent, Svenja, though seemingly Dutch and Scandinavian, is not common anywhere outside of German-speaking countries. Sven can also be spelled with a "w" - Swen - but is pronounced as Sven. The Icelandic version is ''Sveinn'' (); the Faroese version is Sveinur ().

Styxosaurus
''Styxosaurus'' is a genus of plesiosaur of the family Elasmosauridae. ''Styxosaurus'' lived during the Campanian age of the Cretaceous period. Three species are known: ''S. snowii'', ''S. browni'', and ''S. rezaci''. Discovery The holotype specimen of ''Styxosaurus snowii'' a complete skull and 20 vertebrae and was first described by S.W. Williston ''Styxosaurus'' is named for the mythological River Styx ('), which separated the Greek underworld from the world of the living. The ''-saurus'' part comes from the Greek ' (), meaning "lizard" or "reptile." The type specimen was found on Hell Creek in Logan County, Kansas, which is the source of the genus name coined by Samuel Paul Welles, who described the genus in 1943. Another more complete specimen, SDSMT 451, was discovered near Iona, South Dakota, also in the US, in 1945. The specimen was originally described and named ''Alzadasaurus pembertoni'' by Welles and Bump (1949) and remained so until it was synonymized with ''S. s ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium,'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
