Nostolepis is an extinct genus of acanthodian fish which lived in the Late Silurian (Pridoli) to Middle Devonian (Lochkovian). Members of the genus include Nostolepis gracilis and Nostolepis striata. [1]
Bovines comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur.
Ovenbirds or furnariids are a large family of small suboscine passerine birds found from Mexico and Central to southern South America. They form the family Furnariidae. This is a large family containing around 315 species and 70 genera. The ovenbird, which breeds in North America, is not a furnariid – rather it is a distantly related bird of the wood warbler family, Parulidae.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa.
Tragelaphus is a genus of medium-to-large-sized spiral-horned antelopes. It contains several species of bovines, all of which are relatively antelope-like. Species in this genus tend to be large in size and lightly built, and have long necks and considerable sexual dimorphism. Elands, including the common eland, are embedded within this genus, meaning that Taurotragus must be subsumed into Tragelaphus to avoid paraphyly. Alternatively, Taurotragus could be maintained as a separate genus, if the nyala and the lesser kudu are relocated to their own monospecific genera, respectively Nyala and Ammelaphus. Other generic synonyms include Strepsiceros and Boocercus. The name "Tragelaphus" comes from the mythical tragelaph.
Lontra is a genus of otters from the Americas.
Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America.
Aethomys is a genus of rodent from Africa. They are commonly referred to as rock rats, bush rats or rock mice.
Climatius is an extinct genus of spiny shark. This genus is known from the Early Devonian (Lochkovian) of Europe, previously considered Silurian remains actually belong to Nostolepis instead.
Pytilia is a genus of small brightly coloured seed-eating birds in the family Estrildidae. They are distributed across Africa.
Andreolepis is an extinct genus of prehistoric fish, which lived around 420 million years ago. It was described by Walter Gross in 1968 based on scales found in the Hemse Formation in Gotland, Sweden. It is placed in the monogeneric family Andreolepididae and is generally regarded as a primitive member of the class Actinopterygii based on its ganoid scale structure; however some new research regards it as a stem group of osteichthyans.
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus.
Cerrejonemys wayuunaiki is an extinct podocnemid turtle which existed in Colombia during the Paleogene period; the Middle to Late Paleocene epoch.
Carabinae is a subfamily of ground beetles in the family Carabidae. There are about 10 genera and more than 1,400 described species in Carabinae. The Carabinea include 2 tribes, the Cychrini Laporte, 1834 and Carabini Latreille, 1802. The Carabini Latreille is divided into 2 sub-tribes, the Carabina Latreille, 1802 and Ceroglossina Vacher de Lapouge, 1927.
Bashuchelys is an extinct genus of bashuchelyid Middle Jurassic turtle from the Sichuan Basin in the People's Republic of China. As of 2011, it is the only known genus of the family Bashuchelyidae.
Machadoella is a genus of parasitic alveolates in the phylum Apicomplexa.
Myriospora is a genus of parasitic alveolates belonging to the phylum Apicomplexa.
Maaqwi is an extinct genus of large marine diving bird from the Late Cretaceous of Hornby Island, British Columbia, Canada. The genus name Maaqwi comes from the Coast Salish "ma'aqwi" meaning "water bird," and the specific epithet cascadensis reflects the fossil's origin from the Cascadia region of Western North America. The genus is known from a single specimen, RBCM.EH2008.011.01120. It consists of a coracoid, humerus, ulna, and radius in a nodule of mudstone. The specimen is housed in the Royal British Columbia Museum. Maaqwi had an estimated body mass of 1.5 kg.
Campocraspedon is a genus of ichneumonid wasp in the insect order Hymenoptera. It comprises six species.
Lupulella is a genus of canine found in Africa. This genus consists of only two extant species, the black-backed jackal and the side-striped jackal.
