Omosaurus Hastiger
''Omosaurus'' is a dubious genus of extinct crurotarsan reptile, possibly a phytosaur, from the Late Triassic (Carnian) of North Carolina. Only scant remains are known, which makes ''Omosaurus'' hard to classify. The type, and only species, ''Omosaurus perplexus'', was named and described in 1856 by Joseph Leidy. Discovery and naming In the middle of the nineteenth century, geologist Professor Ebenezer Emmons discovered several reptilian teeth in the colliery of the Chatham company in North Carolina. In 1856, the fossils in his collection were described by paleontologist Joseph Leidy. Leidy combined the teeth with some vertebrae and ribs; adding to them an osteoderm or scute found in the same strata by Professor Michael Tuomey, he named the whole ''Omosaurus perplexus'' based on the holotype specimen BMNH 46013.J. Leidy, (1856), "Notice of remains of extinct vertebrated animals discovered by Professor E. Emmons", ''Proceedings of the Academy of Natural Sciences of Philadelphia' ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Hoplitosaurus
''Hoplitosaurus'' (meaning "Hoplite lizard") was a genus of armored dinosaur related to ''Polacanthus''. It was named from a partial skeleton found in the ?Barremian-age Lower Cretaceous Lakota Formation of Custer County, South Dakota. It is an obscure genus which has been subject to some misinterpretation of its damaged remains. Although there was a push to synonymize it with ''Polacanthus'' in the late 1980s-early 1990s, ''Hoplitosaurus'' has been accepted as a valid albeit poorly known genus in more recent reviews. History and Taxonomy The holotype specimen, USNM 4752, was discovered in 1898 by Nelson Horatio Darton, near Buffalo Gap Station, and consisted of ribs, caudal vertebrae, part of a right scapulocoracoid, parts of both humeri, a right femur, and a variety of armor (including tall spines).Lucas, F.A. (1901). A new dinosaur, ''Stegosaurus marshi'', from the Lower Cretaceous of South Dakota. ''Proceedings of the United States National Museum'' 23(1224):591-592.Gilmor ...

Stegosaur
Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, Africa, South America and Asia. Their geographical origins are unclear; the earliest unequivocal stegosaurian, ''Huayangosaurus taibaii'', lived in China. Stegosaurians were armored dinosaurs (thyreophorans). Originally, they did not differ much from more primitive members of that group, being small, low-slung, running animals protected by armored scutes. An early evolutionary innovation was the development of spikes as defensive weapons. Later species, belonging to a subgroup called the Stegosauridae, became larger, and developed long hindlimbs that no longer allowed them to run. This increased the importance of active defence by the thagomizer, which could ward off even large predators because the tail was in a higher position, pointing ...

Crocodilia
Crocodilia (or Crocodylia, both ) is an order of mostly large, predatory, semiaquatic reptiles, known as crocodilians. They first appeared 95 million years ago in the Late Cretaceous period ( Cenomanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. Members of the order's total group, the clade Pseudosuchia, appeared about 250 million years ago in the Early Triassic period, and diversified during the Mesozoic era. The order Crocodilia includes the true crocodiles (family Crocodylidae), the alligators and caimans (family Alligatoridae), and the gharial and false gharial (family Gavialidae). Although the term 'crocodiles' is sometimes used to refer to all of these, crocodilians is a less ambiguous vernacular term for members of this group. Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top ...

Frederick Augustus Lucas
Frederic Augustus Lucas, Sc.D. (March 25, 1852 – February 9, 1929) was a zoologist who served as a curator of the Brooklyn Museum and director of the American Museum of Natural History. He was an expert on the osteology and anatomy of birds. Biography Career Frederic A. Lucas was prominent in the Great American Museum movement, which sought to bring Natural Science to the American public. He eventually became Curator in Chief of the Brooklyn Museum, in Brooklyn, New York, (1904) and subsequently enjoyed an appointment as director at the American Museum of Natural History in Manhattan (1911). Formative years The son of Augustus Henry, a merchant seaman who was captain of a sailing vessel, he accompanied his father on two long voyages, the first (1861-1862) at the age of 9 and the second (1869-1870) when he was 17. His mother was Eliza Oliver, and his paternal great-grandmother Ruby Fuller was a descendant of Dr Samuel Fuller on the Mayflower. He became fascinated with sea life, ...

Plesiosaur
The Plesiosauria (; Greek: πλησίος, ''plesios'', meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous ''Plesiosaurus'', was named in 1821. Since then, more than a hundred valid ...

Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code ). Historically, syntypes were often explicitly designated as such, and under the present ICZN this is a requirement (Art. 72.3), but modern attempts to publish species or subspecies descriptions based on syntypes are generally frowned upon by practicing taxonomists, and most are gradually being replaced by lectotypes. Those that still ex ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Etymology
Etymology ()The New Oxford Dictionary of English (1998) – p. 633 "Etymology /ˌɛtɪˈmɒlədʒi/ the study of the class in words and the way their meanings have changed throughout time". is the study of the history of the Phonological change, form of words and, by extension, the origin and evolution of their semantic meaning across time. It is a subfield of historical linguistics, and draws upon comparative semantics, Morphology_(linguistics), morphology, semiotics, and phonetics. For languages with a long recorded history, written history, etymologists make use of texts, and texts about the language, to gather knowledge about how words were used during earlier periods, how they developed in Semantics, meaning and Phonological change, form, or when and how they Loanword, entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct information about forms that are too old for any direct information to be available. By analyzing related ...
