Arstanosaurus Akkurganensis
''Arstanosaurus'' (meaning "Arstan lizard" after the Arstan well) is a genus of hadrosauroid dinosaur from the Santonian-Campanian-age Upper Cretaceous Bostobe Formation, Kazakhstan. It has had a confusing history, being considered both a hadrosaurid and a ceratopsid, or both at the same time ( chimeric). History The genus was based on a partial left maxilla (holotype AAIZ 1/1 or IZ AN KSSR 1/1), with the lower end of a left femur (AAIZ 1/2) possibly referable. Both were found at Akkurgan-Boltyk near Qyzylorda.Shilin, F.V., and Suslov, Y.V. (1982). A hadrosaur from the northeastern Aral Region. ''Paleontological Journal'' 1982(1):132-136 ranslated version This is not much material for naming a new genus, and it was largely ignored until the mid-1990s, when the hypothesis that it was really a ceratopsid appeared.Nesov, L.A.

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qyzylorda
Kyzylorda ( kk, Қызылорда, translit=Qyzylorda, ), formerly known as Kzyl-Orda (russian: Кзыл-Орда), Ak-Mechet (Ак-Мечеть), Perovsk (Перовск), and Fort-Perovsky (Форт-Перовский), is a city in south-central Kazakhstan, capital of Kyzylorda Region and former capital of the Kazakh ASSR from 1925 to 1927. The city has a population of 242,462 (2020 Census). It historically developed around the Syr Darya river and the site of a Kokand fortress. The population of the city with nearby villages is 312,861 (2020 Census). History A settlement existed under Seljuk, the founder of the Seljuk dynasty. The modern city had its beginnings in 1817 as the site of a Kokand fortress known as Ak-Mechet, or ''white mosque''.Pospelov, p. 24 The later-famous Yaqub Beg was once the fort's commander, but he was apparently not in command during the final battle. In 1853, during the Russian conquest of Turkestan, the fort was taken by Russian troops und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hadrosaurs
Hadrosaurids (), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as '' Edmontosaurus'' and ''Parasaurolophus'', was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, South America and Antarctica. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effe ...

Timeline Of Hadrosaur Research
A timeline is a display of a list of events in chronological order. It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time. This timescale is dependent on the events in the timeline. A timeline of evolution can be over millions of years, whereas a timeline for the day of the September 11 attacks can take place over minutes, and that of an explosion over milliseconds. While many timelines use a linear timescale—especially where very large or small timespans are relevant -- logarithmic timelines entail a logarithmic scale of time; some "hurry up and wait" chronologies are depicted with zoom lens metaphors. History Time and space, particularly the line, are intertwined concepts in human thought. The line is ubiquitous in clocks in t ...

Herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 '' Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ...

Quadrupedal
Quadrupedalism is a form of locomotion where four limbs are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four limbs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all entities that could be described as ‘quadrupedal’ are tetrapods. This last meaning includes certain artificial objects; almost all quadruped ''organisms'' are tetrapods (with the exception of some raptorial arthropods adapte ...

Biped
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning 'two feet' (from Latin ''bis'' 'double' and ''pes'' 'foot'). Types of bipedal movement include walking, running, and hopping. Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs (a group that includes crocodiles and dinosaurs) developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes ( australopithecines, including humans) as well as various other extinct groups evolving ...

Gadolosaurus
This list of informally named dinosaurs is a listing of dinosaurs (excluding Aves; birds and their extinct relatives) that have never been given formally published scientific names. This list only includes names that were not properly published ("unavailable names") and have not since been published under a valid name (see list of dinosaur genera for valid names). The following types of names are present on this list: * ''Nomen nudum'', Latin for "naked name": A name that has appeared in print but has not yet been formally published by the standards of the International Commission on Zoological Nomenclature. ''Nomina nuda'' (the plural form) are invalid, and are therefore not italicized as a proper generic name would be. * ''Nomen manuscriptum'', Latin for "manuscript name": A name that appears in manuscript but was not formally published. A ''nomen manuscriptum'' is equivalent to a ''nomen nudum'' for everything except the method of publication, and description. * ''Nomen ex d ...

Bayan Shireh Formation
The Bayan Shireh Formation (also known as Baynshiree/Baynshire, Baynshirenskaya Svita or Baysheen Shireh) is a geological formation in Mongolia, that dates to the Cretaceous period. It was first described and established by Vasiliev et al. 1959. Description The Bayan Shireh Formation is primarily composed by varicoloured claystones and sandstones with calcareous concretions and characterized by grey mudstones and yellowish-brown medium grained sandstones. Up to thick, the most complete sections are found in the eastern Gobi Desert, consisting of fine-grained, often cross-stratified gray sandstone interbedded with claystone and concretionary, intraformational conglomerates with relatively thick units of red to brown mudstone in the upper part. The Baynshire and Burkhant localities are mainly composed by mudstone, siltstone, sandstone, and conglomerates, with most of their sedimentation being fluvial. The environments that were present on the Bayan Shireh Formation consisted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Batyrosaurus
''Batyrosaurus'' is an extinct genus of herbivorous basal hadrosauroid dinosaur known from the Late Cretaceous Bostobe Formation (Santonian to Campanian stage) of central Kazakhstan. It contains a single species, ''Batyrosaurus rozhdestvenskyi''. It is possible that ''Batyrosaurus'' represents the same taxon as the doubtful '' Arstanosaurus akkurganensis'' as both were found from the same formation. The type species ''Batyrosaurus rozhdestvenskyi'' was in 2012 named and described by Pascal Godefroit, François Escuillié, Yuri Bolotsky and Pascaline Lauters. The generic name is derived from the ''Batyr'', the Kazakh hero warriors. The specific name honours Anatoly Konstantinovich Rozhdestvensky. The holotype, AEHM 4/1, was found near Akkurgan in a layer of the Bostobinskaya Formation dating from the Santonian-Campanian, about eighty-four millions year old. It consists of a partial skeleton, including a partial skull, the lower jaws, sixty individual teeth, the sterna, the ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
