Anochetus Brevidentatus
''Anochetus brevidentatus'' is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola. ''A. ambiguus'' is one of eight species in the ant genus ''Anochetus'' to have been described from fossils found in Dominican amber and is one of a number of ''Anochetus'' species found in the Greater Antillies. History and classification ''Anochetus brevidentatus'' is known from two solitary fossil insects which are inclusions in transparent chunks of Dominican amber. The amber was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America, and up to southern Mexico. The type specimen was collected from the La Toca Mine near las Aguitas, while the second specimen is from an undetermined amber mine. Both are from fossil bearing rocks of the Cordillera Septentrional mountains in the northern Dominican Republic. The amber dates from at least the Burdigalian stage of the Miocene, based o ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Gaster (insect Anatomy)
The gaster is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita ( bees, wasps and ants). This begins with abdominal segment III on most ants, but some make a constricted postpetiole out of segment III, in which case the gaster begins with abdominal segment IV. Certain ants in the genus '' Cataglyphis'', specifically ''Cataglyphis bicolor'' and ''Cataglyphis fortis'', have a cubiform petiole that allows them to decrease their inertia Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law ... (and therefore increase their speed) by raising their gaster into an upright position. References Insect anatomy {{insect-anatomy-stub de:Gaster ...

Mesosoma
The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings. In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk. In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on the low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anochetus Lucidus
''Anochetus lucidus'' is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola.

The specimens were collected from an undetermined amber mine in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic.

State Museum Of Natural History Stuttgart
The State Museum of Natural History Stuttgart (german: Staatliches Museum für Naturkunde Stuttgart), abbreviated SMNS, is one of the two state of Baden-Württemberg's natural history museums. Together with the State Museum of Natural History Karlsruhe (Staatliches Museum für Naturkunde Karlsruhe) it is one of the most important repositories for state-owned natural history collections. Exhibitions are shown in two buildings, both situated in the Rosenstein park in Stuttgart: the Löwentor Museum (German: Museum am Löwentor) houses the paleontology and geology exhibitions, while the Museum Rosenstein in Rosenstein Palace focuses on biology and natural history. Every year, the SMNS is visited by about 110,000 people. History Prior to World War II, the natural history collection of Baden-Württemberg was located at the Neckarstraße in downtown Stuttgart. A part of the exhibits were destroyed during the war, when the original building was destroyed by fire after Allied bombin ...
