Haidomyrmex Cerberus FANTWEB00017 Head
''Haidomyrmex'' is an extinct genus of ants in the formicid subfamily Haidomyrmecinae, and is one of nine genera placed in the subfamily Haidomyrmecinae. The genus contains three described species ''Haidomyrmex cerberus'', ''Haidomyrmex scimitarus'', and ''Haidomyrmex zigrasi''. All three are known from single Late Cretaceous fossils which have been found in Asia. ''H. cerberus'' is the type species and ''Haidomyrmex'' the type genus for the subfamily Haidomyrmecinae. History and classification ''Haidomyrmex,'' is known from three solitary adult fossil specimens which are composed of mostly complete adult females which have been preserved as an inclusions in transparent chunk of Burmese amber. The amber specimens entombing ''H. scimitarus'', and ''H. zigrasi'' were recovered from deposits in Kachin State, west of Myitkyna town in Myanmar. In contrast, type specimen of ''H. cerberus'' was collected in the early 1900s from an unspecified location in Myanmar. Burmese amber ha ...

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Cerberus
In Greek mythology, Cerberus (; grc-gre, Κέρβερος ''Kérberos'' ), often referred to as the hound of Hades, is a multi-headed dog that guards the gates of the Underworld to prevent the dead from leaving. He was the offspring of the monsters Echidna and Typhon, and was usually described as having three heads, a serpent for a tail, and snakes protruding from multiple parts of his body. Cerberus is primarily known for his capture by Heracles, the last of Heracles' twelve labours. Descriptions Descriptions of Cerberus vary, including the number of his heads. Cerberus was usually three-headed, though not always. Cerberus had several multi-headed relatives. His father was the multi snake-headed Typhon, and Cerberus was the brother of three other multi-headed monsters, the multi-snake-headed Lernaean Hydra; Orthrus, the two-headed dog who guarded the Cattle of Geryon; and the Chimera, who had three heads: that of a lion, a goat, and a snake. And, like these close relatives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Myrmica
''Myrmica'' is a genus of ants within the subfamily Myrmicinae. It is widespread throughout the temperate regions of the Holarctic and high mountains in Southeast Asia. The genus consists of around 200 known species and additional subspecies, although this figure is likely to rise as soon as the Chinese and Nearctic fauna lists are revised. Inquilines The genus contains a number of inquiline species (commensal symbionts), other ''Myrmica'' species that manage to invade the nest of their host. Subsequently, they use hormones to manipulate the host colony in such a way that eggs of the host queen develop into workers, and parasite brood into sexuals. Hence, the parasite is not able to sustain a colony of its own, but uses host resources instead. Similarly, larvae of the butterfly genus '' Maculinea'' (a junior synonym of ''Phengaris'', family Lycaenidae) and of the southern armyworm, live inside ''Myrmica'' nests where they are either directly fed by ants or prey upon ant broo ...

Greek Underworld
In mythology, the Greek underworld, or Hades, is a distinct realm (one of the three realms that makes up the cosmos) where an individual goes after death. The earliest idea of afterlife in Greek myth is that, at the moment of death, an individual's essence (''psyche'') is separated from the corpse and is transported to the underworld. In early mythology (e.g., Homer's ''Iliad'' and ''Odyssey'') the dead were indiscriminately grouped together and lead a shadowy post-existence; however, in later mythology (e.g., Platonic philosophy) elements of post-mortem judgment began to emerge with good and bad people being separated (both spatially and with regards to treatment). The underworld itself— commonly referred to as Hades, after its patron god, but also known by various metonyms—is described as being located at the periphery of the earth, either associated with the outer limits of the ocean (i.e., ''Oceanus'', again also a god) or beneath the earth. Darkness and a lack of sunlig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

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 ...
