Halszkaraptor
''Halszkaraptor'' (; meaning "Halszka Osmólska, Halszka's seizer") is a genus of waterfowl-like dromaeosaurid dinosaurs from Mongolia that lived during the Late Cretaceous period. It contains only one known species, ''Halszkaraptor escuilliei''. The type specimen (holotype) has been compared to the bones of neontology, extant crocodilians and water bird, aquatic birds, and found evidence of a semiaquatic lifestyle, while some researchers question about semiaquatic ecology. A phylogenetics, phylogenetic analysis revealed it was a member of the basal (phylogenetics), basal subfamily Halszkaraptorinae, along with ''Mahakala (dinosaur), Mahakala'' and ''Hulsanpes''. History of discovery The holotype specimen of ''Halszkaraptor'' likely came from the Djadochta Formation at Ukhaa Tolgod in southern Mongolia, and was illegally removed by Fossil collecting#Fossil trade, fossil poachers. The fossil found its way to Japan and Great Britain, being owned by several Fossil collecting, coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halszkaraptorinae
Halszkaraptorinae is a Basal (phylogenetics), basal ("primitive") subfamily of Dromaeosauridae (or possibly Unenlagiidae) that includes the enigmatic Genus, genera ''Halszkaraptor'', ''Natovenator'', ''Mahakala (dinosaur), Mahakala'', and ''Hulsanpes''. Halszkaraptorines are definitively known only from Late Cretaceous strata in Asia, specifically in Mongolia. Following the recent discovery of ''Natovenator'', a member of the subfamily, the group is confirmed to have a semiaquatic lifestyle. History of discovery The first known remains of halszkaraptorines were found in sandstone sediments in 1970 during a Polish-Mongolian expedition at the Barun Goyot Formation, Gobi Desert. Later in 1982 they were described by Poles, Polish paleontologist, palaeontologist Halszka Osmólska and used as the holotype for the new genus and species ''Hulsanpes perlei'', honoring the Mongolian paleontologist Altangerel Perle. Although the affinities of these fossils were not fully understood, they we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dromaeosaurid
Dromaeosauridae () is a family of feathered theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek ('), meaning 'runner', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film ''Jurassic Park''; a few types include the term "raptor" directly in their name and have come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia, South America and Antarctica, with some fossils giving credence to the possibility that they inhabited Australia as well. They first appeared in the mid-Jurassic Period (late Bathonian stage, about 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene ...

Hulsanpes
''Hulsanpes'' ( meaning " Khulsan foot") is a genus of halszkaraptorine theropod dinosaurs that lived during the Late Cretaceous in what is now the Barun Goyot Formation of Mongolia, about 75-72 million years ago. The remains were found in 1970 and formally described in 1982 by Halszka Osmólska, who noted that the genus is represented by an immature individual. ''Hulsanpes'' represents the first record of the basal dromaeosaurid subfamily Halszkaraptorinae. History of discovery The first fossil remains of ''Hulsanpes'' were discovered in 1970 during the third Polish-Mongolian expedition at Khulsan in the Gobi Desert. Twelve years later, the type species, ''Hulsanpes perlei'', was named and described by the Polish palaeontologist Halszka Osmólska in 1982. ''Hulsanpes'' is based on the holotype fossil specimen ZPAL MgD-I/173, uncovered in a sandstone layer of the Barun Goyot Formation, dating from the Late Campanian (roughly 72 million years ago). It consists of a partial bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahakala (dinosaur)
''Mahakala'' ( from संस्कृतम् (''Sanskrit''), named for Mahakala, one of eight protector deities ( dharmapalas) in Tibetan Buddhism) is a genus of halszkaraptorine theropod dinosaur from the Campanian-age (about 80 million years ago) Upper Cretaceous Djadokhta Formation of Ömnögovi, Mongolia. It is based on a partial skeleton found in the Gobi Desert. ''Mahakala'' was a small dromaeosaurid, and its skeleton shows features that are also found in early troodontids and avialans. Despite its late appearance, it is among the most basal dromaeosaurids. Its small size, and the small size of other basal deinonychosaurians, suggests that small size appeared before flight capability in birds. Description ''Mahakala'' was a small dromaeosaurid, measuring long and weighing . The holotype specimen, IGM 100/1033, consists of a partial skeleton including skull bones, vertebrae, limb bones, and portions of the pelvis and shoulder girdle. Although this in ...

Djadochta Formation
The Djadochta Formation (sometimes transcribed and also known as Djadokhta, Djadokata, or Dzhadokhtskaya) is a highly fossiliferous geological formation situated in Central Asia, Gobi Desert, dating from the Late Cretaceous period, about 75 million to 71 million years ago. The type locality is the Bayn Dzak locality, famously known as the Flaming Cliffs. Dinosaur, mammal, and other reptile remains are among the fossils that have been recovered from the formation. Excavation history The Djadochta Formation was first documented and explored—though only a single locality—during paleontological expeditions of the American Museum of Natural History in 1922–1925, which were part of the Central Asiatic Expeditions. The expeditions were led by Roy Chapman Andrews, in company of Walter Willis Granger as chief paleontologist and field team. The team did extensive exploration at the Bayn Dzak (formerly Shabarakh Usu) region, which they nicknamed Flaming Cliffs given that at sunset th ...

Halszka Osmólska
Halszka Osmólska (September 15, 1930 – March 31, 2008) was a Polish paleontologist who had specialized in Mongolian dinosaurs. Biography She was born in 1930 in Poznań. In 1949, she began to study biology at Faculty of Biology and Earth Sciences of the University of Poznań before moving to Warsaw and studying at the Warsaw University, which she graduated from in 1955. Since then she worked at the Institute of Paleobiology of the Polish Academy of Sciences (PAN). Between 1983–1988, she served as the institute's director. She was a member of the Polish–Mongolian expeditions to the Gobi Desert (1963–1965 and 1967–1971) and she described many finds from these rocks, often with Teresa Maryańska. Among the dinosaurs she described are: * '' Elmisaurus'' (and Elmisauridae) (1981), '' Hulsanpes'' (1982), '' Borogovia'' (1987), and '' Bagaraatan'' (1996) * with Maryańska, '' Homalocephale'', '' Prenocephale'', and '' Tylocephale'' (and Pachycephalosauria)(1974), '' Baga ...

Dinosaurs
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Collecting
Fossil collecting (sometimes, in a non-scientific sense, fossil hunting) is the collection of fossils for scientific study, hobby, or profit. Fossil collecting, as practiced by amateurs, is the predecessor of modern paleontology and many still collect fossils and study fossils as amateurs. Professionals and amateurs alike collect fossils for their scientific value. A commercial trade in fossils has also long existed, with some of this being practised illegally. Process Locating fossils Rock type Fossils are generally found in sedimentary rock with differentiated strata representing a succession of deposited material. The occurrence of fossil bearing material depends on environmental factors before and after the time of preservation. After death, the first preserving factor is a rapid burial in water bodies or terrestrial sediment which would help in preserving the specimen. These rocks types are usually termed clastic rock, and are further subdivided into fine, medium and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
