Aphaenogaster Praerelicta
''Aphaenogaster praerelicta'' is an extinct species of ant in the subfamily Myrmicinae known from a solitary Late Oligocene to Early Miocene fossil found in Mexico. At the time of description ''A. praerelicta'' was one of three ''Aphaenogaster'' species known from Mexico. History and classification ''Aphaenogaster praerelicta'' is known from a solitary fossil insect which is an inclusion in a transparent chunk of Mexican amber along with three flies, two springtails, a wasp, and some pollen grains. Mexican amber is recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. The amber dates from between 22.5 million years old, representing the youngest sediments of the Balumtun Sandstone, and the 26 million year old La Quinta Formation. This age range straddles the boundary between the Late Oligocene and Early Miocene and is complicated by both formations being secondary deposits for the amber: the age range represents only the youngest that it might be. ...

Late Oligocene
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appearance of ...

Hymenaea Mexicana
''Hymenaea mexicana'' is an extinct legume species in the family Fabaceae described from a series of isolated fossil petals, leaflets, and amber. The species is known from a group of Late Oligocene to Early Miocene locations in southern Mexico. It is one of two extinct ''Hymenaea'' species placed close to the living species ''Hymenaea verrucosa'' and along with ''Hymenaea allendis'', is one of the two extinct species which have been found in Mexican amber. History and classification ''Hymenaea mexicana'' is known from a series of fossil flowers and leaves which are inclusions in transparent chunks of Mexican amber. The species where the amber was also found in was in Brazil which could indicate where the specie Hymenaea mexicana could have been located as well. The specimens were collected over the course of twenty five years with a total of thirty amber specimens being examined for the description of the species. Mexican amber is recovered from fossil-bearing rocks in the Sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphaenogaster Mexicana
''Aphaenogaster'' is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica. They are often confused with '' Pheidole'' or '' Pheidologeton''. These two have major and minor workers, while ''Aphaenogaster'' has only a single worker caste. ''Pheidole'' has three-segmented clubs on its antennae, while ''Aphaenogaster'' has four segments and a larger body size. ''Pheidologeton'' has 11-segmented antennae, while the antennae in ''Aphaenogaster'' are 12-segmented.Genus ''Aphaenogaster'' In Australia, they often build dense, conspicuous nests.Richards, P.J.

Dominican Amber
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree ''Hymenaea protera''. Dominican amber differentiates itself from Baltic amber by being nearly always transparent, and it has a higher number of fossil inclusions. This has enabled the detailed reconstruction of the ecosystem of a long-vanished tropical forest.George Poinar, Jr. and Roberta Poinar, 1999. ''The Amber Forest: A Reconstruction of a Vanished World'', (Princeton University Press) Age A study in the early 1990s returned a date up to 40 million years old. However, according to Poinar, Dominican amber dates from Oligocene to Miocene, thus about 25 million years old. The oldest, and hardest of this amber comes from the mountain region north of Santiago. The ''La Cumbre'', ''La Toca'', ''Palo Quemado'', ''La Bucara'', and ''Los Cacaos'' mining sites in the ''Cordillera Septentrional'' not far from Santiago. Amber has also been found in the south-eastern Bayaguana/Sabana de la Mar a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphaenogaster Amphioceanica
''Aphaenogaster amphioceanica'' is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found in amber on Hispaniola. At the time of description ''A. amphioceanica'' was one of two ''Aphaenogaster'' species known from the Caribbean islands. History and classification ''Aphaenogaster amphioceanica'' is known from a solitary fossil insect which is an inclusion in a transparent chunk of Dominican amber along with a spider, a mite, and six woodlice. The amber was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The amber specimen, number Do-4629-B; which entombs the holotype, is currently preserved in the Division of Invertebrate Zoology collections at the in Stuttgart, Germany. The holotype was collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic. The amber dates f ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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 ...

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 ...
