Sebecus Icaeorhinus
''Sebecus'' (meaning "Sebek" in Latin) is an extinct genus of Sebecidae, sebecid crocodylomorph from Eocene of South America. Like other sebecosuchians, it was entirely terrestrial and carnivorous. The genus is currently represented by two species, the type species, type ''S. icaeorhinus'' and ''S. ayrampu''. Several other species have been referred to ''Sebecus'', but were later reclassified as their own genera. History and species Named by United States, American paleontologist George Gaylord Simpson in 1937, ''Sebecus'' was one of the first known sebecosuchians. Simpson described the type species, ''S. icaeorhinus'', from a fragmented skull and lower jaw found in the Sarmiento Formation. The specimen was discovered by the American Museum of Natural History's First Scarritt Expedition to Patagonia, during 1930 and 1931. Teeth had been known since 1906 when Argentine paleontologist Florentino Ameghino associated them with carnivorous dinosaurs. The more complete material found ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarmiento Formation
The Sarmiento Formation (Spanish: ''Formación Sarmiento''), in older literature described as the Casamayor Formation, is a geological formation in Chubut Province, Argentina, in central Patagonia, which spans around 30 million years from the mid-Eocene to the early Miocene. It predominantly consists of pyroclastic deposits, which were deposited in a semi-arid environment. It is divided up into a number of members. The diverse fauna of the Sarmiento Formation, including a variety of birds, crocodilians, turtles and snakes, also includes many mammals such as South American native ungulates ( notoungulates, litopterns, astrapotheres) as well as armadillo Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, al ...s, and caviomorph rodents.

Crocodile
Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa. Although they appear similar, crocodiles, alligators and the gharial belong to separate biological families. The gharial, with its narrow snout, is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upper and lower jaws of the crocodiles are the same width, and the teeth in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latinisation (literature)
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attri ...

Sobek Oxford
Sobek (also called Sebek or Sobki, cop, Ⲥⲟⲩⲕ, Souk) was an ancient Egyptian deity with a complex and elastic history and nature. He is associated with the Nile crocodile or the West African crocodile and is represented either in its form or as a human with a crocodile head. Sobek was also associated with pharaonic power, fertility, and military prowess, but served additionally as a protective deity with apotropaic qualities, invoked especially for protection against the dangers presented by the Nile. Sobek has been famed for having been revered by the first female Pharaoh by the Nebty name Sat-Sekhem-Nebet-Tawy Sobekneferu, present both in the female Pharaoh's nomen, Sobek'Neferu (sbk-nfrw - Beauty of Sobek), and her praenomen Ka'Sobek'Re (The Ka of Sobek-Ra). History Sobek enjoyed a longstanding presence in the ancient Egyptian pantheon, from the Old Kingdom of Egypt (c. 2686–2181 BCE) through the Roman period (). He is first known from several different Pyramid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baurusuchus
''Baurusuchus'' is an extinct member of the ancestral crocodilian lineage, which lived in Brazil from 90 to 83.5 million years ago, in the Late Cretaceous period. Technically, it is a genus of baurusuchid mesoeucrocodylian. It was a terrestrial predator and scavenger, about long and in weight. ''Baurusuchus'' lived during the Turonian to Santonian stages of the Late Cretaceous Period, in Adamantina Formation, Brazil. It gets its name from the Brazilian Bauru Group ("Bauru crocodile"). It was related to the earlier-named '' Cynodontosuchus rothi'', which was smaller, with weaker dentition. The three species are ''B. pachechoi'', named after Eng Joviano Pacheco, its discoverer, ''B. salgadoensis'' (named after General Salgado County in São Paulo, Brazil) and ''B. albertoi'' (named after Alberto Barbosa de Carvalho, Brazilian paleontologist). The latter species is disputed (see phylogeny section). Its relatives include the similarly sized '' Stratiotosuchus'' from the Adaman ...

Baurusuchidae
Baurusuchidae is a Gondwanan family of mesoeucrocodylians that lived during the Late Cretaceous. It is a group of terrestrial hypercarnivorous crocodilians from South America (Argentina and Brazil) and possibly Pakistan. Baurusuchidae has been, in accordance with the PhyloCode, officially defined as the least inclusive clade containing '' Cynodontosuchus rothi, Pissarrachampsa sera,'' and ''Baurusuchus pachecoi.'' Baurusuchids have been placed in the suborder Baurusuchia, and two subfamilies have been proposed: Baurusuchinae and Pissarrachampsinae. Genera Several genera have been assigned to Baurusuchidae. ''Baurusuchus'' was the first, being the namesake of the family. Remains of ''Baurusuchus'' have been found from the Late Cretaceous Bauru Group of Brazil in deposits that are Turonian - Santonian in age. In addition to ''Baurusuchus'', five other South American crocodyliforms have been assigned to Baurusuchidae: '' Campinasuchus'', '' Cynodontosuchus'', '' Pissarrachampsa' ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', " chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Crocodyliform
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.
