Magyarosaurus Dacus
''Magyarosaurus'' ("Hungarian people, Hungarian lizard") is a genus of Insular dwarfism, dwarf sauropod dinosaur from late Cretaceous Period (geology), Period (early to late Maastrichtian) in Romania. It is one of the smallest-known adult sauropods, measuring less than long and weighing less than . The type species, type and monotypic taxon, only species is ''Magyarosaurus dacus''. It has been found to be a close relative of ''Rapetosaurus'' in the family Saltasauridae in the sauropod clade Titanosauria in a 2005 study. Discovery Remains belonging to at least ten individuals have been recovered since 1895 from the Hunedoara region (Sânpetru Formation) in the area which was, at the time of their discovery, Hungary, but is now western Romania. Initially they were named ''Titanosaurus dacus'', the specific name referring to the Dacians (who had lived in that place about 2000 years ago), by Franz Nopcsa von Felső-Szilvás, Baron Nopcsa in 1915.

Magyarosuchus
''Magyarosuchus'' is an extinct monotypic genus of metriorhynchoid described for the first time from fossils discovered in the Kisgerecse Marl Formation in Hungary Hungary is a landlocked country in Central Europe. Spanning much of the Pannonian Basin, Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and .... The type species ''Magyarosuchus fitosi'' lived during the Toarcian, about 180 million years ago.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Paleontology
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uriash
''Uriash'' is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous (Maastrichtian) of Romania. The holotype of this genus was originally referred to ''Magyarosaurus hungaricus'', which is now classified in a separate genus, '' Petrustitan''. Discovery and naming In 1914, the Hungarian geologist Ottokár Kadić in the Pârâul Budurone ravine near Vălioara, discovered a skeleton of a sauropod which was markedly larger than previously found sauropod remains in the area. In 1916, the discovery, consisting of limb bones and eight vertebrae, was reported in the scientific literature. By 12 January 1927 two vertebrae had been sent to Friedrich von Huene at the University of Tübingen. Von Huene described these in 1932, preliminary referring them to a ?''Magyarosaurus hungaricus'', presently ''Petrustitan''. In 2021 the site was rediscoveredBotfalvai, G., Csiki-Sava, Z., Kocsis, L., Albert, G., Magyar, J., Bodor, E.R., Ţabara, D., Ulyanov, A., & Makadi, L. 2021. "‘X ...

Petrustitan
''Petrustitan'' is a eutitanosaurian sauropod dinosaur from the Late Cretaceous (Maastrichtian) of Romania. The type and only species is ''P. hungaricus'', originally assigned to the genus '' Magyarosaurus''. History of discovery In 1932, Friedrich von Huene erected the genus '' Magyarosaurus'' and assigned three species based on sauropod specimens recovered from the Sânpetru Formation: ''M. dacus'' (the type species), ''M. hungaricus'' and ''M. transsylvanicus''.von Huene, F. (1932). "Die fossile Reptil-Ordnung Saurischia, ihre Entwicklung und Geschichte." ''Mong. Geol. Pal.'', 4(1) pts. 1 and 2, viii +361 pp. However, subsequent analyses considered only ''M. dacus'' as a valid species of ''Magyarosaurus'', with "''M.''" ''transsylvanicus'' representing a chimera and partially a junior synonym of ''M. dacus'', and with "''M.''" ''hungaricus'' representing a distinct genus. In 2025, Díez Díaz and colleagues reassigned "''M.''" ''hungaricus'' to a new genus ''Petrustitan'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimera (paleontology)
In paleontology, a chimera is a fossil that was reconstructed with elements coming from more than a single species or genus of animal. In other words, they are mistakes or sometimes hoaxes made by paleontologists, putting together parts that do not come from the same organism. List of paleontological chimeras * "Archaeoraptor" * '' Avalonianus'' * '' Bagaraatan'' * '' Beipiaognathus''? * ''Dakotaraptor''? * '' Dalianraptor''? * '' Dravidosaurus'' * '' Eocarcharia'' * ''Kryptops''? * '' Kootenichela''? * '' Lametasaurus''? * '' Luchibang'' * '' Ornithopsis hulkei'' * Piltdown Man * '' Polacanthoides''? * '' Precursor''? * ''Protoavis'' * ''Saurophaganax?'' * "Teihivenator" * ''"Tylosaurus" capensis'' * '' Ultrasauros'' * ''Xenodens ''Xenodens'' (from Greek language, Greek and Latin for "strange tooth") is a potentially Nomen dubium, dubious extinct genus of marine lizard belonging to the mosasaur family.

Dacians
The Dacians (; ; ) were the ancient Indo-European inhabitants of the cultural region of Dacia, located in the area near the Carpathian Mountains and west of the Black Sea. They are often considered a subgroup of the Thracians. This area includes mainly the present-day countries of Romania and Moldova, as well as parts of Ukraine, Moravian Banovina, Eastern Serbia, Northern Bulgaria, Slovakia, Hungary and Southern Poland. The Dacians and the related Getae spoke the Dacian language, which has a debated relationship with the neighbouring Thracian language and may be a subgroup of it. Dacians were somewhat culturally influenced by the neighbouring Scythians and by the Celtic invasion of the Balkans, Celtic invaders of the 4th century BC. Name and etymology Name The Dacians were known as ''Geta'' (plural ''Getae'') in Ancient Greek writings, and as ''Dacus'' (plural ''Daci'') or ''Getae'' in Roman Empire, Roman documents, but also as ''Dagae'' and ''Gaete'' as depicted on ...

Hunedoara
Hunedoara (; ; ) is a municipiu, city in Hunedoara County, Transylvania, Romania. It is located in southwestern Transylvania near the Poiana Ruscă Mountains, and administers five villages: Boș (''Bós''), Groș (''Grós''), Hășdat (''Hosdát''; ''Hochstätten''), Peștișu Mare (''Alpestes''), and Răcăștia (''Rákosd''). The city includes the most important Gothic architecture, Gothic-style secular building in Transylvania: the Hunyad Castle, which is closely connected with the Hunyadi family. The castle was destroyed by fire five times, but underwent many reconstructions from Austro-Hungarian and later Romanian authorities. Besides the castle, the town developed as a production center for iron and a market for the mountain regions nearby. During the 20th century, Hunedoara's population increased to 86,000 inhabitants. The city contained Hunedoara steel works, the largest steel works in Romania (until Galați took the lead), but activity gradually diminished after the Roma ...
