Tarchia
''Tarchia'' (meaning "brainy one") is a genus of herbivorous ankylosauridae, ankylosaurid dinosaur from the late Cretaceous of Mongolia. Discovery and naming In 1970, a Polish-Mongolian expedition discovered an ankylosaurian skull near Khulsan. In 1977, Teresa Maryańska named and described the type species ''Tarchia kielanae''. The generic name is derived from Mongolian language, Mongolian тархи (''tarkhi'', "brain") and Latin ''~ia'', in reference to a brain size presumed larger than that of the related form ''Saichania''. The specific name (zoology), specific name honours Professor Zofia Kielan-Jaworowska, the leader of the expedition. The holotype, ZPal MgD-I/111, was discovered in the Upper Cretaceous (possibly Campanian-Maastrichtian) Barun Goyot Formation (previously known as the 'Lower Nemegt Beds') of the Nemegt Basin of Mongolia. It consists of a skull roof, braincase and rear skull elements. Maryańska referred three additional specimens: ZPAL MgDI/43, a large po ...

Minotaurasaurus
''Minotaurasaurus'' (meaning “Minos'-bull reptile”) is a monospecific genus of ankylosaurid dinosaur that lived in Mongolia during the Late Cretaceous (late Campanian stage, ~75-71 Ma) in what is now the Djadochta Formation. The type and only species, ''Minotaurasaurus ramachandrani'', is known from two skulls, a cervical vertebra and a cervical half ring. It was named and described in 2009 in paleontology, 2009 by Clifford Miles and Clark Miles. The first fossils of ''Minotaurasaurus'' were illegally exported out of Mongolia.It has been suggested to be a synonym of ''Tarchia'' but more recent publications consider it as a distinct genus. ''Minotaurasaurus'' was a medium-sized ankylosaurid, with an estimated length of 4.2 metres (13.8 feet), although it may have reached larger sizes as the type specimen represents an immature individual. Although not a lot of postcranial material is known, it would have had a tail club that may have been used for protection against predators o ...

Saichania
''Saichania'' (Mongolian meaning "beautiful one") is a genus of herbivorous ankylosaurid dinosaur from the Late Cretaceous period of Mongolia. The first fossils of ''Saichania'' were found in the early 1970s in Mongolia. In 1977 the type species ''Saichania chulsanensis'' was named. The description of this species has been based on limited fossil material; especially the rear of the animal is not well known. ''Saichania'' was more robustly built than other members of the Ankylosauridae, measuring in length and in body mass. Neck vertebrae, shoulder girdle, ribs and breast bones were fused or firmly connected. Its body was flat and low-slung, standing on four short legs. The forelimbs were very powerful. The head was protected by bulbous armour tiles. It could defend itself against predators like '' Tarbosaurus'' with a tail-club. On the torso keeled osteoderms were present. ''Saichania'' bit off plants in its desert habitat with a horny beak and processed them in its wide hin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyoplosaurus
''Dyoplosaurus'' (meaning “double-armoured lizard”) is a monospecific genus of ankylosaurid dinosaur from Alberta that lived during the Late Cretaceous (middle Campanian, ~76.5–75 Ma) in what is now the Dinosaur Park Formation. ''Dyoplosaurus'' represents a close relative of '' Scolosaurus'' and '' Anodontosaurus'', two ankylosaurids known from the Horseshoe Canyon and Dinosaur Park Formation. Discovery and naming The holotype specimen was obtained in 1919 from the bottom ten metres of the Dinosaur Park Formation by Levi Sternberg, near what is now the Red Deer River in Alberta, Canada. The holotype specimen, ROM 784, consists of a partial skull roof, mandible fragments with teeth, osteoderms, skin impressions, articulated post-thoracic vertebrae, partial thoracic ribs, a partial ilium, both ischia, tail club, associated radius, metacarpal, femur, tibia, fibula, and pes. The holotype is currently housed at the Royal Ontario Museum. Two specimens were referred to ''Dyoplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankylosauridae
Ankylosauridae () is a family of armored dinosaurs within Ankylosauria, and is the sister group to Nodosauridae. The oldest known ankylosaurids date to around 122 million years ago and went extinct 66 million years ago during the Cretaceous–Paleogene extinction event. These animals were mainly herbivorous and were obligate quadrupeds, with leaf-shaped teeth and robust, scute-covered bodies. Ankylosaurids possess a distinctly domed and short snout, wedge-shaped osteoderms on their skull, scutes along their torso, and a tail club. Ankylosauridae is exclusively known from the Northern Hemisphere, with specimens found in North America, Europe, and Asia. The first discoveries within this family were of the genus ''Ankylosaurus'', by Peter Kaiser and Barnum Brown in Montana in 1906. Brown went on to name Ankylosauridae and the subfamily Ankylosaurinae in 1908. Anatomy Ankylosaurids are stout, solidly built, armoured dinosaurs. They possess accessory ossifications on cranial bones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barun Goyot Formation
The Baruungoyot Formation (also known as Barun Goyot) is a geological formation dating to the Late Cretaceous Period. It is located within and is widely represented in the Gobi Desert Basin, in the Ömnögovi Province of Mongolia. Description It was previously known as the Lower Nemegt Beds occurring beneath the Nemegt Formation and above the Djadokhta Formation. It has been suggested that the Djadokhta and Baruungoyot Formations are lower and upper parts, respectively, of the same lithological unit and the boundary between the two does not exist. The stratotype of the Baruungoyot Formation is the Khulsan locality, east of Nemegt. At Nemegt, only the uppermost barungoyotian beds are visible. The ''Red Beds of Khermeen Tsav'' are also considered part of the Baruungoyot Formation. It is approximately in thickness,Gradzinski, R.; & Jerzykiewicz, T. (1974).

Teresa Maryańska
Teresa Maryańska (1937 – 3 October 2019) was a Polish paleontologist who specialized in Mongolian dinosaurs, particularly pachycephalosaurians and ankylosaurians. She is considered not only as one of Poland's but also one of the world's leading experts on dinosaurs. Career Initially, Mary's studies were regarding invertebrate paleontology. However, she became a member of the 1964, 1965, 1970, and 1971 Polish–Mongolian expeditions to the Gobi Desert, and changed her focus. She described many finds from these fossils, often with Halszka Osmólska. In 1974, Maryanska and Halszka Osmólska were among the first "women to describe new kinds of dinosaurs". Since 1961, Maryańska was affiliated with the Muzeum Ziemi of the Polska Akademia Nauk and was vice-director there from 1976 to 2006, when she retired. Some of the dinosaurs she described: * '' Homalocephale'' (1974), with Halszka Osmólska * ''Prenocephale'' (1974), with Halszka Osmólska * '' Tylocephale'' (1974), with ...

Species Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maastrichtian
The Maastrichtian ( ) is, in the International Commission on Stratigraphy (ICS) geologic timescale, the latest age (geology), age (uppermost stage (stratigraphy), stage) of the Late Cretaceous epoch (geology), Epoch or Upper Cretaceous series (stratigraphy), Series, the Cretaceous geologic period, Period or system (stratigraphy), System, and of the Mesozoic geologic era, Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). It is named after the city of Maastricht, the capital and largest city of the Limburg (Netherlands), Limburg province in the Netherlands. The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary period, Tertiary extinction event) occurred at the end of this age. In this extinction event, mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-kn ...

Tatyana Tumanova
Tatiana (or Tatianna, also romanized as Tatyana, Tatjana, Tatijana, etc.) is a female name of Sabine-Roman origin that became widespread in Eastern Europe. Origin Tatiana is a feminine, diminutive derivative of the Sabine—and later Latin—name Tatius. King Titus Tatius was the name of a legendary ruler of the Sabines, an Italic tribe living near Rome around the 8th century BC. After the Romans absorbed the Sabines, the name Tatius remained in use in the Roman world, into the first centuries of Christianity, as well as the masculine diminutive Tatianus and its feminine counterpart, Tatiana. While the name later disappeared from Western Europe including Italy, it remained prevalent in the Hellenic world of the Eastern Roman Empire, and later spread to the Byzantine-influenced Orthodox world, including Russia. In that context, it originally honoured the church Saint Tatiana, who was tortured and martyred in the persecutions of the Roman Emperor Alexander Severus, c. 230 ...
