Heptasteornis
''Heptasteornis'' is the name given to a dubious genus of alvarezsaurid dinosaur from the Late Cretaceous. The type (and only known) species is ''Heptasteornis andrewsi'', described as a presumed gigantic prehistoric owl in 1975. It was previously included in '' Elopteryx nopcsai'' and indeed the holotypes of both were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however (see below).Harrison & Walker (1975) The material was discovered in Romania by Franz Nopcsa, in the late Maastrichtian Sânpetru Formation ( Rognacian faunal stage, deposited c. 68 - 66 million years ago) of the Haţeg Basin in Transylvania. The scientific name means "C.W. Andrews' Transylvanian bird", after the namer of ''Elopteryx'', and Ancient Greek ''hepta'' (ἑπτά) "seven" + ''asty'' (άστυ) "city" + ''ornis'' (όρνις) "bird"; the Latin ''septum urbium'' or the German ''Siebenbürgen'' - mean ...

Bradycneme
''Bradycneme'' (meaning "ponderous leg") is a genus of theropod dinosaur from the Maastrichtian-age Upper Cretaceous Sânpetru Formation of the Hațeg Basin, Transylvania, Romania. The genus contains a single species, ''Bradycneme draculae'', known only from a partial right lower leg (specimen BMNH A1588), which its original describers believed came from a giant owl. History In 1975, Harrison and Walker described two "bradycnemids" from Romania: ''B. draculae'' and '' Heptasteornis andrewsi''. These specimens had initially been assigned to the supposed pelecaniform bird '' Elopteryx nopcsai''. The generic name, ''Bradycneme'', comes from the Ancient Greek (), meaning "slow, ponderous" and (), meaning "leg", as the holotype, BMNH A1588, a wide distal tibiotarsus found by Maud Eleanora Seeley, would be very stout if the animal had been an owl, with a body height of about .Harrison & Walker (1975) The specific name, ''draculae'', is derived from Romanian ', meaning "the dr ...

Elopteryx Nopcsai
''Elopteryx'' is a genus of Paraves, paravian theropod dinosaur based on fragmentary fossils found in Late Cretaceous rocks of Romania. The single species, ''Elopteryx nopcsai'', was known only from very incomplete material until new specimens were reported in the 21st century. ''Balaur bondoc'' might represent a junior synonym of this taxon. History of discovery and naming Initial finds In the late nineteenth or early twentieth century, the famous Hungary, Hungarian paleontologist Franz Nopcsa von Felső-Szilvás found near Sânpetru, Sînpetru, in what is now the Romanian region of Transylvania, some bone fragments of a small theropod. These were acquired by the British Museum of Natural History. In 1913, curator Charles William Andrews named these as the type species ''Elopteryx nopcsai''. The genus name ''Elopteryx'' is from Ancient Greek ''helos'' (ἕλος), "marsh" + ''pteryx'' (πτέρυξ), "wing". The specific name (zoology), specific name honors Nopcsa. Initially, '' ...

Alvarezsaurid
Alvarezsauridae is a family of small, long-legged dinosaurs. Although originally thought to represent the earliest known flightless birds, they are now thought to be an early diverging branch of maniraptoran theropods. Alvarezsaurids were highly specialized. They had tiny but stout forelimbs, with compact, bird-like hands. Their skeletons suggest that they had massive breast and arm muscles, possibly adapted for digging or tearing. They had long, tube-shaped snouts filled with tiny teeth. They have been interpreted as myrmecophagous, adapted to prey on colonial insects such as termites, with the short arms acting as effective digging instruments to break into nests. '' Alvarezsaurus'', the type genus of the family, was named for the historian Gregorio Álvarez. History of study Bonaparte (1991) described the first alvarezsaurid, '' Alvarezsaurus calvoi'', from an incomplete skeleton found in Patagonia, Argentina. Bonaparte also named a family, Alvarezsauridae, to contain it. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sânpetru Formation
The Sânpetru Formation is an Maastrichtian, early Maastrichtian geologic Formation (geology), formation. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. It is located in Romania, near Sânpetru village, part of Sântămăria-Orlea commune. It forms a component of the Hațeg Island fauna. Description The Sânpetru Formation outcrop, crops out in the central to southern Țara Hațegului, Hațeg Basin along the Bărbat (river), Bărbat River and comprises sandstones and mudstones deposited in a wet floodplain depositional environment, environment characterized by braided river, braided fluvial channels. The formation is correlated with the Densuș-Ciula Formation of the northern section of the same basin, both dating to the Maastrichtian of the Late Cretaceous.Solomon & Codrea, 2015, p.26 Fossil content Amphibians Turtles Squamates Crocodyliformes Ornithischian ...

Scientific Name
In Taxonomy (biology), 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 grammar, 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 (biology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anatomical Terms Of Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Tibiotarsi
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae. These small ornithischian dinosaurs were unrelated to birds and the similarity of their foot bones is best explained by convergent evolution. See also *Bird anatomy References * Proctor, Nobel S.
