Halszka Osmólska
Halszka Osmólska (September 15, 1930 – March 31, 2008) was a Polish paleontologist who had specialized in Mongolian dinosaurs. Early life, family and education Osmólska 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. Thereafter, she studied at the University of Warsaw, graduating in 1955. Career Osmólska worked at the Institute of Paleobiology of the Polish Academy of Sciences (PAN). Between 1983 and 1988, she served as the institute's director. She was a member of the Polish–Mongolian expeditions to the Gobi Desert (1963–1965, 1967–1971), and she described many finds from these rocks, often with Teresa Maryańska. Among the dinosaurs she described: * '' Deinocheirus'' (1967), with Ewa Roniewicz * '' Gallimimus'' (1972), with Roniewicz and Rinchen Barsbold * '' Pachycephalosauria'' (1974), with Maryańska * ''Bagaceratops'' (1975), with Maryańska * '' Barsboldia'' (1981) ...

Pachycephalosauria
Pachycephalosauria (; from Greek παχυκεφαλόσαυρος for 'thick headed lizards') is a clade of ornithischian dinosaurs. Along with Ceratopsia, it makes up the clade Marginocephalia. With the exception of two species, most pachycephalosaurs lived during the Late Cretaceous Period, dating between about 85.8 and 66 million years ago. They are exclusive to the Northern Hemisphere, all of them being found in North America and Asia. They were all bipedal, herbivorous/omnivorous animals with thick skulls. Skulls can be domed, flat, or wedge-shaped depending on the species, and are all heavily ossified. The domes were often surrounded by nodes and/or spikes. Partial skeletons have been found of several pachycephalosaur species, but to date no complete skeletons have been discovered. Often isolated skull fragments are the only bones that are found. Candidates for the earliest-known pachycephalosaur include ''Ferganocephale adenticulatum'' from Middle Jurassic Period strata ...

Tochisaurus
''Tochisaurus'' (meaning "Ostrich lizard") is a genus of small troodontid theropod dinosaur from the Late Cretaceous Period of Mongolia. The type (and only named) species is ''Tochisaurus nemegtensis''. In 1948, a Soviet-Mongolian expedition found the remains of a small theropod in the Gobi Desert near Nemegt. In 1987 the find was reported by Sergei Kurzanov and later that year discussed by Halszka Osmólska who suggested it could represent a specimen of the troodontid ''Borogovia''. Later Osmólska understood it was a species new to science. It was formalized by Kurzanov and Osmólska in 1991 as ''Tochisaurus nemegtensis''. The generic name is derived from Mongolian ''toch, "ostrich", in reference to the fact that the foot, like with that bird, is functionally didactyl, i.e. has only two weight-bearing toes. The specific name refers to the Nemegt.Kurzanov S.M., and Osmólska, H., 1991, "''Tochisaurus nemegtensis'' gen. et sp. n., a new troodontid (Dinosauria, Theropoda) from M ...

Goyocephale
''Goyocephale'' is an extinct genus of pachycephalosaurian ornithischian that lived in Mongolia during the Late Cretaceous about 76 million years ago. It was first described in 1982 by Altangerel Perle, Teresa Maryańska and Halszka Osmólska for a disarticulated skeleton with most of a skull, part of the forelimb and hindlimb, some of the pelvic girdle, and some vertebrae. Perle ''et al.'' named the remains ''Goyocephale lattimorei'', from the Mongolian language, Mongolian гоё (''goyo''), meaning "decorated", and the Ancient Greek κεφαλή (''kephale''), for head. The species name honours Owen Lattimore. Description ''Goyocephale'' is known from a partial skull, including both mandibles, the skull roof, part of the occiput, part of the braincase region, the anatomical terms of location#Anterior and posterior, posterior skull, the premaxilla, and the maxilla. The posterior edge of the skull roof, at the edge of the squamosal bones, has many small bony bumps, which would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tylocephale
''Tylocephale'' (meaning "swollen head") is a genus of pachycephalosaurid dinosaur, a group of dome-headed, herbivorous ornithischians, that lived during the Late Campanian stage (75-73 million years ago) of the Late Cretaceous in what is now Mongolia. It is known from a partial skull and associated mandible that were unearthed in 1971 by a Polish-Mongolian Expedition to the Barun Goyot Formation of the Gobi Desert. The specimen was described in 1974 by Polish paleontologists Teresa Maryańska and Halszka Osmólska as a new genus and species. It was average-sized for a pachycephalosaur, reaching in length and in body mass. The skull is triangular in back view, the widest point being at the jugals with an apex at the top of the dome. ''Tylocephale'''s dome is the tallest known from a pachycephalosaur. This dome is also unusually thick and rugose on its exterior. Behind the dome, an array of spikes, nodes, and tubercules protrude posteriorly over the neck. The eyebrow ridge wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prenocephale
''Prenocephale'' (meaning "sloping head") is a genus of small pachycephalosaurid dinosaur from the Late Cretaceous Nemegt Formation of Mongolia. It was similar in many ways to its close relative, ''Homalocephale''. Discovery The holotype specimen, Z. Pal. No. MgD-I/104, consists of an isolated yet well-preserved skull, dorsal vertebrae and ribs, sacrum, femora, and caudal vertebrae. It was discovered by the Polish-Mongolian Paleontological Expedition and was found at the Nemegt locality, in a sandstone layer of the Nemegt Formation. Additional specimens have been recovered from the Bügiin Tsav, Guriliin Tsav, and Tsaagan Khushuu localities of the formation. Description Adult ''Prenocephale'' measured in length and in body mass. Unlike the flattened wedge-shaped skull of ''Homalocephale'' (a possible juvenile trait also potentially seen in early growth stages of ''Pachycephalosaurus''), the head of ''Prenocephale'' was rounded and sloping. The dome had a row of small bony spik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homalocephale
''Homalocephale'' (from Greek ὁμαλός, ''homalos'', "even", and κεφαλή, ''kephalē'', "head") is a genus of pachycephalosaurid dinosaur that lived during the Late Cretaceous period of what is now the Nemegt Formation, Mongolia, about 70 million years ago. The genus was described in 1974 by Halszka Osmólska and Teresa Maryańska, and consists of a single species, ''H. calathocercos''. Though ''Homalocephale'' has been regarded as a synonym (and juvenile form) of ''Prenocephale'', juvenile specimens of the latter indicate that they were distinct. ''Homalocephale'' was long and possibly an omnivore. Discovery The type species, ''H. calathocercos'', was described from an incomplete skull and postcranial material (holotype MPC-D 100/1201) from the Nemegt locality of the Nemegt Formation. The specimen has large openings on the top of the skull, a distinct frontoparietal suture, low and long infratemporal fenestrae, and a large, round eye socket. The forehead is notably ...

Bagaraatan
''Bagaraatan'' (/'ba-ɣa-raa-tan/ meaning 'small' ''baɣa'' + 'carnivorous animal, beast of prey' ''araatan'' in Mongolian) is a genus of theropod dinosaur from the Late Cretaceous period. Its fossils were found in the Nemegt Formation of Mongolia. ''Bagaraatan'' may have been around 3 to 4 metres (9.8 to 13 ft) in length. History The type species, ''B. ostromi'', was described by Halszka Osmólska in 1996. Initially, the post-cranial ( ZPAL MgD-I/108) skeleton had been described as "bird-like", while the skull was noted to exhibit features of several different theropod groups. The material that warranted this conclusion was later found to be a chimaera of two non-avian dinosaurs, with some of the post-crania (hand bones, left femur, tibiotarsus, and rib) being referred to an indeterminate caenagnathid, possibly '' Elmisaurus''. The material that is considered the holotype, which includes the mandible, axial skeleton, pelvis, and one pedal phalanx, likely indicates that ''B ...

Borogovia
''Borogovia'' is a troodontid theropod dinosaur genus which lived during the Late Cretaceous Period, in what is now Mongolia. It contains one species, ''Borogovia gracilicrus.'' Discovery and naming In 1971, a Polish-Mongolian expedition discovered the remains of a small theropod at the Altan Uul IV site, in the Nemegt Basin of Ömnögovĭ province. In 1982, upon describing '' Hulsanpes perlei'', the find was reported by Halszka Osmólska and considered by her to be a possible specimen of '' Saurornithoides''.Osmólska, H., (1982), "''Hulsanpes perlei'' n.g.n.sp. (Deinonychosauria, Saurisichia, Dinosauria) from the Upper Cretaceous Barun Goyot Formation of Mongolia", ''Neues Jahrbuch für Geologie und Paläontologie, Monatshefte'' 1982(7): 440-448 Later she concluded that it represented a species new to science. In 1987, Osmólska named and described the type species ''Borogovia gracilicrus''. The generic name is derived from the fantasy creatures known as 'borogoves' i ...

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 brainca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elmisauridae
Caenagnathidae is a family of derived caenagnathoid dinosaurs from the Cretaceous of North America and Asia. They are a member of the Oviraptorosauria, and relatives of the Oviraptoridae. Like other oviraptorosaurs, caenagnathids had specialized beaks, long necks, and short tails, and would have been covered in feathers. The relationships of caenagnathids were long a puzzle. The family was originally named by Raymond Martin Sternberg in 1940 as a family of flightless birds. The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods, and the discovery of more complete caenagnathid remains revealed that ''Chirostenotes pergracilis'', originally named on the basis of a pair of hands, and ''Citipes elegans'', originally thought to be an ornithomimid, named from a foot, were caenagnathids as well. Discovery The name ''Caenagnathus'' (and hence Caenagnathidae) means "recent jaws"—when first discovered, it was thought that caenagnathid ...
