Generic name (biology) in the context of "Aedes"

The first part of the name – the 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 genus Homo and within this genus to the species Homo sapiens. Tyrannosaurus rex is likely the most widely known binomial. The formal introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work Species Plantarum in 1753. But as early as 1622, Gaspard Bauhin introduced in his book Pinax theatri botanici (English, Illustrated exposition of plants) containing many names of genera that were later adopted by Linnaeus. Binomial nomenclature was introduced in order to provide succinct, relatively stable and verifiable names that could be used and understood internationally, unlike common names which are usually different in every language.

Otavia antiqua is an ancient sponge-like multicellular organism found in the Otavi Group (the generic name being the namesake) in the Etosha National Park, Namibia. It is claimed to be the oldest animal fossil, being found in rock aged between 760 and 550 million years ago. The oldest Otavia fossils are from the Tonian period, before the Cryogenian glaciations, but the latest found were from the Nama Group rocks of the Ediacaran period.

The affinities of these fossils, along with other paleontological evidence for Precambrian sponges, are disputed.

Brachiosaurus (/ˌbrækiəˈsɔːrəs/) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 155.6 to 145.5 million years ago. It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States. Riggs named the dinosaur Brachiosaurus altithorax; the generic name is Greek for "arm lizard", in reference to its proportionately long arms, and the specific name means "deep chest". Brachiosaurus is estimated to have been between 18 and 22 meters (59 and 72 ft) long; body mass estimates of the subadult holotype specimen range from 28.3 to 46.9 metric tons (31.2 to 51.7 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods. Atypically, Brachiosaurus had longer forelimbs than hindlimbs, which resulted in a steeply inclined trunk, and a proportionally shorter tail.

Brachiosaurus is the namesake genus of the family Brachiosauridae, which includes a handful of other similar sauropods. Most popular depictions of Brachiosaurus are in fact based on Giraffatitan, a genus of brachiosaurid dinosaur from the Tendaguru Formation of Tanzania. Giraffatitan was originally described by German paleontologist Werner Janensch in 1914 as a species of Brachiosaurus, B. brancai, but moved to its own genus in 2009. Three other species of Brachiosaurus have been named based on fossils found in Africa and Europe; two are no longer considered valid, and a third has become a separate genus, Lusotitan.

Lepomis or true sunfish is a genus of North American freshwater fish from the family Centrarchidae in the order Centrarchiformes. The generic name Lepomis derives from the Greek λεπίς ("scale") and πῶμα ("cover", "plug", "operculum"). The genus' most recognizable species is perhaps the bluegill.

Some Lepomis species can grow to a maximum overall length of 41 cm (16 in), though most average around 10–20 cm (3.9–7.9 in). Many species are sought by anglers as popular panfishes, and large numbers are bred and stocked in lakes, rivers, ponds and wetlands. They are widely distributed throughout the freshwater lakes and river tributaries of the United States and Canada, and several species have been translocated and flourished around the world, even becoming pests. Aquarium trade in some Lepomis species is prohibited in Germany for this reason.
