Hadongsuchus
The binomial name “''Hadongsuchus acerdentis''” refers to the skull remain of an extinct "protosuchian" crocodyliform from the Hasandong Formation of Hadong, South Korea. Discovery The Hasandong Formation has been dated to the late Aptian and earliest Albian, between 118.0 ± 2.6 Ma and 112.4 ± 1.3 Ma. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. A complete fossil skull was discovered in 2002, and the genus was named in 2005 based on this fossil. Certain features of the third premaxillary tooth help distinguish it from other related crocodylomorphs. The estimated size of ''Hadongsuchus'' was around 50 cm in length. Like other protosuchians, it is believed to have been a fully terrestrial cursorial animal with a semi-erect posture. The binomial name of the type species ''H. acerdentis'' means "sharp-toothed crocodile from Hadon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hadong
Hadong County (, ''Hadong-gun'') is a county in South Gyeongsang Province, South Korea. It is on the far-west side of the province, bordering South Jeolla Province. The county office is located at Hadeong-eup. History The county of Hadong was called ''Dasachon'' (, "county of much sand") when it was a part of the Jin state, later becoming a part of ''Nangnoguk'' (), one of twelve statelets of the Byeonhan confederacy. According to the ''History of the Three Kingdoms'', the region was called ''Handasa-gun'' (), then changed into ''Hadong-gun'' in 757 CE, during the reign of King Gyeongdeok of Silla. During the Goryeo dynasty, the area was known as ''Hadong-hyeon'' (). In 1414, during the reign of the Joseon-era King Taejong, it became known as ''Hanamhyeon'' () with ''Namhaehyeon'' (). It was raised to the status of ''Hadongdohobu'' () in 1740, in the thirtieth year of King Sukjong's reign. During the Korean War the region was the site of a North Korean attack on US Army forces, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crocodyliforms
Crocodyliformes is a clade of crurotarsan archosaurs, the group often traditionally referred to as "crocodilians". They are the first members of Crocodylomorpha to possess many of the features that define later relatives. They are the only pseudosuchians to survive the K-Pg extinction event. In 1988, Michael J. Benton and James M. Clark argued that all traditional names for well-known groups of animals should be restricted to their crown clades, that is, used only for natural groups comprising all living members of any given lineage. This posed a problem for the crocodilians, because the name Crocodylia, while used in various ways by various scientists, had always included not only living crocodilians but many of their extinct ancestors known only from the fossil record.Benton, M.J. and Clark, J.M.

Protosuchidae
Protosuchidae was a family of crocodylomorph reptiles from the Late Triassic, Jurassic, and Cretaceous time periods. They were closely related to the Gobiosuchidae. Distribution Triassic protosuchids are known from Lesotho, Argentina, and Arizona. Jurassic protosuchids are known from Nova Scotia, Poland, South Africa, and Arizona. Cretaceous protosuchids are known from China. Ecology Protosuchids were carnivores. An unnamed species of protosuchids known only from teeth was an herbivore. See also *Protosuchia Protosuchia is a group of extinct Mesozoic crocodyliforms. They were small in size (~1 meter in length) and terrestrial.

Zosuchus
''Zosuchus'' ("Zos anyoncrocodile") is a genus of basal, Late Cretaceous crocodyliform from the Mongolia. The type species is ''Z. davidsoni'', after preparator Amy Davidson. The name was emended to ''davidsonae'' in 2004. Discovery It was found in the Redbeds of Zos Canyon ( Djadokhta Formation) in the Gobi Desert of Mongolia by expeditions organized by the American Museum of Natural History, and described by palaeontologists Diego Pol and Mark Norell in 2004. Material of ''Z. davidsonae'' consists of five specimens: * IGM 100/1305 (holotype): isolated skull and lower jaws * IGM 100/1304 * IGM 100/1306 * IGM 100/1307 * IGM 100/1308 Morphology This genus had a very short snout. Systematics Pol & Norell (2004) found ''Zosuchus davidsoni'' to be sister to ''Sichuanosuchus'' and '' Shantungosuchus'', the three forming a basal clade of crocodyliforms based on the presence of a ventrally deflected posterior region of the mandibular rami. A 2018 cladistic analysis found ''Zos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sichuanosuchus
''Sichuanosuchus'' is an extinct genus of crocodylomorph from the Late Jurassic and possibly Early Cretaceous of China. Systematics Poll and Norell (2004) recovered ''Sichuanosuchus'' as sister to ''Shantungosuchus'' and ''Zosuchus'' based on the presence of a ventrally deflected posterior region of the mandibular rami. Buscalioni (2017) recovered ''Sichuanosuchus'' as sister to ''Shantungosuchus'', ''Zosuchus'', and Shartegosuchidae, and Dollman et al. (2018) went further by erecting Shartegosuchoidea for the clade formed by Shartegosuchidae Shartegosuchidae is an extinct family of Late Jurassic and Early Cretaceous crocodylomorphs.

Shantungosuchus
''Shantungosuchus'' is an extinct genus of Early Cretaceous crocodyliform found in China. It includes three species: ''Shantungosuchus chuhsienensis'' and ''S. brachycephalus'', which were both described by Yang Zhongjian – usually referred to as "Young" – in 1961 and 1982, and ''S. hangjinensis'', which was described by Xiao-Chun Wu et al in 1994. ''S. chuhsienensis'' is the type for this genus. Etymology The primary part of ''Shantungosuchus name comes from ''Shan-tung'', the Wade-Giles romanization of ''Shandong'' (), a province located on the eastern coast of the People's Republic of China, where it was first discovered. The second part, ''suchus'' is an Ancient Greek word referring to the Egyptian crocodile deity Sobek that is commonly used as a suffix for crocodylomorph genera and crocodile-like animals in general. Description ''Shantungosuchus chuhsienenis'' was first described from an articulated skeleton that was preserved as an impression of its ventral s ...

Symposium
In ancient Greece, the symposium ( grc-gre, συμπόσιον ''symposion'' or ''symposio'', from συμπίνειν ''sympinein'', "to drink together") was a part of a banquet that took place after the meal, when drinking for pleasure was accompanied by music, dancing, recitals, or conversation.Peter Garnsey, ''Food and Society in Classical Antiquity'' (Cambridge University Press, 1999), p. 13online Sara Elise Phang, ''Roman Military Service: Ideologies of Discipline in the Late Republic and Early Principate'' (Cambridge University Press, 2008), pp. 263–264. Literary works that describe or take place at a symposium include two Socratic dialogues, Plato's '' Symposium'' and Xenophon's '' Symposium'', as well as a number of Greek poems such as the elegies of Theognis of Megara. Symposia are depicted in Greek and Etruscan art that shows similar scenes. In modern usage, it has come to mean an academic conference or meeting such as a scientific conference.

Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Premaxilla
The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla. The "premaxilla" of therian mammal has been usually termed as the incisive bone. Other terms used for this structure include premaxillary bone or ''os premaxillare'', intermaxillary bone or ''os intermaxillare'', and Goethe's bone. Human anatomy In human anatomy, the premaxilla is referred to as the incisive bone (') and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla. It is formed from the ...
