This is a list of common affixes used when scientifically naming species, particularly extinct species for whom only their scientific names are used, along with their derivations. *a-, an-: ''Pronunciation'': /ə/, /a/, /ən/, /an/. ''Origin'': (''a, an-''). ''Meaning'': a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious. *:Examples: ''Anurognathus'' ("tailless jaw"); ''Apus'' ("footless"); '' Apteryx'' ("wingless"); ''Pteranodon'' ("wings without teeth"); Anura ("tailless"); '' Anophthalmus'' ("eyeless") *-acanth, acantho-: ''Pronunciation'': /eɪkænθ/, /eɪkænθoʊ/. ''Origin'': (''ákantha''). ''Meaning'': spine. *:Examples: '' Acanthodes'' ("spiny base"); ''Acanthostega'' ("spine roof"); coelacanth ("hollow spine"); ''Acrocanthosaurus'' ("high- ...

Affix
In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. The main two categories are Morphological derivation, derivational and inflectional affixes. Derivational affixes, such as ''un-'', ''-ation'', ''anti-'', ''pre-'' etc., introduce a semantic change to the word they are attached to. Inflectional affixes introduce a syntactic change, such as singular into plural (e.g. ''-(e)s''), or present simple grammatical tense, tense into present continuous or past tense by adding ''-ing'', ''-ed'' to an English word. All of them are bound morphemes by definition; prefixes and suffixes may be separable affixes. Affixes, infixes and their variations Changing a word by adding a morpheme at its beginning is called ''prefixation'', in the middle is called ''infixation'', and at the end is called ''suffixation''. ''Prefix'' and ''suffix'' may be subsumed under the term ''adfix'', in contrast to ''infix.'' When marking text for interlinear gl ...

Aetobatus
''Aetobatus'' is a genus of eagle rays native to the Atlantic, Pacific and Indian Oceans. It was formerly placed in Myliobatidae, but is now placed in its own family Aetobatidae based on salient differences from myliobatids, especially the pectoral fins joining the head at the level of the eyes.White, W. T. & Naylor, G. J. P. (2016). Resurrection of the family Aetobatidae (Myliobatiformes) for the pelagic eagle rays, genus Aetobatus. Zootaxa 4139, 435–438. 10.11646/zootaxa.4139.3.10 Species There are currently either 3 or 5 recognized extant species in this genus depending on the status of ''A. narinari'': There are also 6 extinct species (only known from fossil remains) placed in this genus: *†'' Aetobatus arcuatus'' *†'' Aetobatus cappettai'' *†'' Aetobatus irregularis'' *†'' Aetobatus punctatus'' *†''Aetobatus poeyi ''Aetobatus'' is a genus of eagle rays native to the Atlantic, Pacific and Indian Oceans.

Archelon
''Archelon'' is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring from head to tail and in body mass. It is known only from the Pierre Shale and has one species, ''A. ischyros''. In the past, the genus also contained ''A. marshii'' and ''A. copei'', though these have been reassigned to ''Protostega'' and ''Kansastega'', respectively. The genus was named in 1896 by American paleontologist George Reber Wieland based on a skeleton from South Dakota, who placed it into the extinct family (biology), family Protostegidae. The leatherback sea turtle (''Dermochelys coriacea'') was once thought to be its closest living relative, but now, Protostegidae is thought to be a completely separate lineage from any living sea turtle. ''Archelon'' had a leathery carapace instead of the hard shell seen in most sea turtles. The carapace may have featured a row of small ridges, each peaking at in heigh ...

Dianthus
''Dianthus'' ( ) is a genus of about 340 species of flowering plants in the family Caryophyllaceae, native mainly to Europe and Asia, with a few species in north Africa and in southern Africa, and one species (''D. repens'') in arctic North America. Common names include carnation (''D. caryophyllus''), pink (''D. plumarius'' and related species) and sweet william (''D. barbatus''). Description The species are mostly herbaceous perennials, a few are annual or biennial, and some are low subshrubs with woody basal stems. The leaves are opposite, simple, mostly linear and often strongly glaucous grey green to blue green. The flowers have five petals, typically with a frilled or pinked margin, and are (in almost all species) pale to dark pink. One species, ''D.'' ''knappii'', has yellow flowers with a purple centre. Some species, particularly the perennial pinks, are noted for their strong spicy fragrance. Taxonomy Species Selected species include: Hybrids ...

Helianthus
''Helianthus'' () is a genus comprising around 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of ''Helianthus'' are native to North America and Central America. The best-known species is the common sunflower (''Helianthus annuus''). This and other species, notably Jerusalem artichoke (''H. tuberosus''), are cultivated in temperateness, temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species ''H. annuus'' typically grows during the summer and into early fall, with the peak growth season being mid-summer. Several perennial ''Helianthus'' species are grown in gardens, but have a tendency to spread rapidly and can become aggressive. On the other hand, the whorled sunflower, ''Helianthus verticillatus'', was listed as an endangered species in 2014 when the U.S. Fish and Wildlife Service issued ...

Amphicyon
''Amphicyon'' is an extinct genus of large carnivorans belonging to the family Amphicyonidae (known colloquially as "bear-dogs"), subfamily Amphicyoninae, from the Miocene epoch. Members of this family received their vernacular name for possessing bear-like and dog-like features. They ranged over North America, Eurasia, and Africa. Taxonomy In a note dated back to May 16, 1836, French geologist Alexandre Leymerie wrote a letter in April that he requested from French palaeontologist Édouard Lartet, which provided details of his exploits in palaeontological sites in the French department of Gers, in particular the commune Sansan. Lartet described his finds of fossil taxons that he found within the sites, including "'' Mastodonte''" (species assigned to it were later reclassified to another mammutid '' Zygolophodon'' and the gomphothere ''Gomphotherium''), "''Dinotherium''" (its species eventually reclassified as either ''Deinotherium'' or ''Prodeinotherium''), "''Rhinoceros' ...

Amphicoelias
''Amphicoelias'' (, meaning "biconcave", from the Greek ἀμφί, ''amphi'': "on both sides", and κοῖλος, ''koilos'': "hollow, concave") is a genus of herbivorous sauropod dinosaur that lived approximately 150 million years ago during the Tithonian (Late Jurassic Period) of what is now Colorado, United States. ''Amphicoelias'' was moderately sized at about in length and in body mass, shorter than its close relative '' Diplodocus''. Its hindlimbs were very long and thin, and its forelimbs were proportionally longer than in relatives. The namesake fossil of the type species ''Amphicoelias altus'', American Museum of Natural History 5764, is uncertain in included material. When described by Edward Drinker Cope shortly after its discovery in 1877, ''Amphicoelias'' was noted to include many back vertebrae, a single pubis, and a femur. However, after purchase and cataloging of the material by the AMNH, Henry Fairfield Osborn and Charles Mook described that the specimen had ...

Amphibian
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Nitrosomonadales
The ''Nitrosomonadales'' are an order of the class ''Betaproteobacteria'' in the phylum ''Pseudomonadota''.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . Like all members of their class, they are Gram-negative. The order is divided into six families: * '' Nitrosomonadaceae'' (type family) comprises the genera '' Nitrosomonas'' (type genus), '' Nitrosolobus'' and '' Nitrosospira''. * '' Methylophilaceae'' comprises the genera '' Methylophilus'' (type genus), '' Methylobacillus'' and '' Methylovorus''. * '' Spirillaceae'' comprises the genus '' Spirillum'' (type genus) * '' Thiobacillaceae'' comprises the genera ''Thiobacillus'' (type genus), '' Annwoodia'', '' Sulfuritortus''. * '' Gallionellaceae'' comprises the genera '' Gallionella'' (type genus), '' Ferriphaselus'', ' ...

Enterobacterales
Enterobacterales is an order of Gram-negative bacteria, Gram-negative, non-spore forming, Facultative anaerobic organism, facultatively anaerobic, rod-shaped bacteria with the class Gammaproteobacteria. The type genus of this order is ''Enterobacter.'' The name Enterobacterales is derived from the Latin term ''Enterobacter'', referring the type genus of the order and the suffix "-ales", an ending used to denote an order. Together, Enterobacterales refers to an order whose nomenclatural type is the genus ''Enterobacter''. Historical Identification and Systematics Enterobacterales was proposed in 2005 under the name "Enterobacteriales". However, the name "Enterobacteriales" was not validated according to the rules of the ''International Code of Nomenclature of Prokaryotes,'' thus it lacked standing in nomenclature, so the name was written in parentheses. "Enterobacteriales" was a monotypic order, containing only the family ''Enterobacteriaceae'', and shared its type genus ''Esch ...

Afrotheria
Afrotheria ( from Latin ''Afro-'' "of Africa" + ''theria'' "wild beast") is a superorder of placental mammals, the living members of which belong to groups that are either currently living in Africa or of African origin: golden moles, elephant shrews (also known as sengis), otter shrews, tenrecs, aardvarks, hyraxes, elephants, sea cows, and several extinct clades. Most groups of afrotheres share little or no superficial resemblance, and their similarities have only become known in recent times due to genetics and molecular studies. Many afrothere groups are found mostly or exclusively in Africa, reflecting the fact that Africa was an island continent from the Cretaceous until the early Miocene around 20 million years ago, when Afro-Arabia collided with Eurasia. Because Africa was isolated by water, Laurasian groups of mammals such as insectivores, rodents, lagomorphs, carnivorans and ungulates could not reach Africa for much of the early to mid-Cenozoic. Instead, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
