Beg (dinosaur)
''Beg'' (after the Himalayan war deity Beg-tse) is a genus of neoceratopsian dinosaur from the early Cretaceous period of Mongolia. The genus contains a single species, ''Beg tse'', known from a partial skull and very fragmentary postcrania. ''Beg'' represents the most basal neoceratopsian currently known. Discovery and naming The holotype, IGM 100/3652, was discovered in 2015 near the town of Tsogt-Ovoo in the Ömnögovi Province of Mongolia. Described from the Ulaanoosh Formation, the specimen is dated to 113 to 94 million years ago, at the boundary of the Lower and Upper Cretaceous. ''Beg'' is named after Beg-tse, a Himalayan deity who is the god of war in Mongolian culture. The deity is often depicted with a rugose face and/or body, similar to the appearance of the preserved skull of the dinosaur. Description Based on the size of the skull, about long, ''Beg'' was most likely a medium-sized basal ceratopsian, similar in size to ''Yinlong'' and ''Liaoceratops.'' ...

Begtse
Begtse (; "Begtse the Great Coat of Mail") is a dharmapala and the lord of war in Tibetan Buddhism, originally a pre-Buddhist war god of the Mongols. Name The name Begtse () is a loanword from Mongolian , meaning "coat of mail". He is also given the name and epithet Jamsaran (), meaning "Great Coat of Mail", which is a translation of the Mongolian. Description Begtse has red skin and orange-red hair, two arms (as opposed to other Mahākālas, who have four or six), three blood-shot eyes and is wielding a sword in his right hand. He also holds a human heart in his right hand. In the stock of his right arm, he holds a bow and arrow and a halberd with bannet. He wears a chainmail shirt, which gave rise to his name, ''Jamsaran''. He wears a Mongolian helmet with a crown of five skulls and four banners in the back. He is also accompanied by his consort, Rikpay Lhamo, and his main general, Laihansorgodog. They are surrounded by Jamsaran's satellites, the twenty-nine butchers. Cult ...

Liaoceratops
''Liaoceratops'', meaning "Liaoning horned face", is a ceratopsian dinosaur believed to be an early relative of the horned ceratopsids. It lived in the Early Cretaceous, 126 million years ago. It was discovered in China by a team of American and Chinese scientists. ''Liaoceratops'' was much smaller than its later relatives, but offers a glimpse into the early evolution of this group of dinosaurs. Discoveries and naming ''Liaoceratops'' was discovered in the famous Liaoning Province of China, where several fossils of feathered dinosaurs have also been collected. The type species ''Liaoceratops yanzigouensis'' was in 2002 named and described by Xu Xing, Peter Makovicky, Wang Xiaolin, Mark Norell and You Hailu. The generic name is derived from Liaoning and the Greek ''keras'', "horn" and ''ops'', "face". The specific name refers to the town Yanzigou. The holotype IVPP V12738 has been found in the Yixian Formation dating from the Barremian. These beds have also yielded fossil ...

Cretaceous Dinosaurs Of Asia
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by the ...

Cenomanian Life
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine speci ...

Albian Life
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Neoceratopsians
Ceratopsia or Ceratopia ( or ; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Europe, and Asia, during the Cretaceous Period, although ancestral forms lived earlier, in the Jurassic. The earliest known ceratopsian, ''Yinlong downsi'', lived between 161.2 and 155.7 million years ago.Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> The last ceratopsian species, ''Triceratops prorsus'', became extinct during the Cretaceous–Paleogene extinction event, . ''Triceratops'' is by far the best-known ceratopsian to the general public. It is traditional for ceratopsian genus names to end in "''-ceratops''", although this is not always the case. One of the first named genera was ''Ceratops'' itself, which lent its name to the group, although it is considered a ''nomen dubium'' today as its fossil remains have no distinguishing characte ...

List Of Short Species Names
Living organisms are known by scientific names. These binomial names can vary greatly in length, and some can be very short; genus or species names composed of only one letter are not allowed by any of the nomenclature codes, but any combination of two letters and above can be valid if it has not been previously used. This list of shortest species names lists the scientific binomials with the fewest letters. The longest scientific species names can be found in the List of long species names. 4 letters *'' Ia io'' Thomas, 1902 – Family Vespertilionidae. The great evening bat is the largest vespertilionid bat, reaching a wingspan of just over half a metre. It occurs in tropical Asia where it lives in limestone caves. Apart from being the shortest scientific name of a living organism (and one of the shortest possible, since anything below 4 letters would not be allowed), it also has the peculiarity of being composed only of vowels. The specific name probably refers to Io, a wom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dinosaur Egg
Dinosaur eggs are the organic vessels in which a dinosaur embryo develops. When the first scientifically documented remains of non-avian dinosaurs were being described in England during the 1820s, it was presumed that dinosaurs had laid eggs because they were reptiles. In 1859, the first scientifically documented dinosaur egg fossils were discovered in France by Jean-Jacques Poech, although they were mistaken for giant bird eggs (birds were not yet recognized as dinosaurs at the time). The first scientifically recognized non-avian dinosaur egg fossils were discovered in 1923 by an American Museum of Natural History crew in Mongolia. Dinosaur eggshell can be studied in thin section and viewed under a microscope. The interior of a dinosaur egg can be studied using CAT scans or by gradually dissolving away the shell with acid. Sometimes the egg preserves the remains of the developing embryo inside. The oldest known dinosaur eggs and embryos are from ''Massospondylus'', which lived ...

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 ...

Sauropods
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...
