Prostylotermes
''Prostylotermes'' is an extinct genus of termite in the isopteran family Stylotermitidae known from two Eocene fossils found in India. The genus contains a single described species, ''Prostylotermes kamboja''. History and classification ''Prostylotermes'' is known from only two fossils, the holotype female and a single paratype male, both of which are inclusions in a transparent chunk of amber. The amber, number "Tad-321C" is housed in the fossil collection of the Birbal Sahni Institute of Palaeobotany in Lucknow, India. Both the holotype and paratype are composed of mostly complete adult termites though some areas of the female were lost on the surface of the amber specimen. Cambay amber dates to between fifty and fifty-two million years old, placing it in the Early to Mid Ypresian age of the Eocene, and was preserved in a brackish shore environment. The amber formed from a dammar type resin which is produced mainly by trees in the family Dipterocarpaceae. The ''Prostylo ...

Stylotermitidae
Stylotermitidae is a family of termites in the order Blattodea Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically .... There are two extinct and one extant genera in Stylotermitidae, with more than 50 described species. Genera These three genera belong to the family Stylotermitidae: * '' Stylotermes'' Holmgren, 1917 * † '' Parastylotermes'' Snyder & Emerson, 1949 * † '' Prostylotermes'' Engel & Grimaldi, 2011 References Further reading * Termites Blattodea families {{termite-stub ...

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the lower Eocene. Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. Stratigraphic definition The Ypresian Stage was introduced in scientific literature by Belgium, Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flanders, Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones.

Dipterocarpaceae
Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus ''Dipterocarpus'', is derived from Greek (''di'' = two, ''pteron'' = wing and ''karpos'' = fruit) and refers to the two-winged fruit. The largest genera are ''Shorea'' (196 species), ''Hopea'' (104 species), ''Dipterocarpus'' (70 species), and ''Vatica'' (65 species).Ashton, P.S. Dipterocarpaceae. In ''Tree Flora of Sabah and Sarawak,'' Volume 5, 2004. Soepadmo, E., Saw, L. G. and Chung, R. C. K. eds. Government of Malaysia, Kuala Lumpur, Malaysia. Many are large forest-emergent species, typically reaching heights of 40–70 m, some even over 80 m (in the genera ''Dryobalanops'', ''Hopea'' and ''Shorea''), with the tallest known living specimen (''Shorea faguetiana'') 93.0 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Se ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Simple Eye In Invertebrates
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are ''camera eyes'' and ...

Pleuron (insect Anatomy)
The pleuron (pl. pleura, from Greek side, rib) is a lateral sclerite of thoracic segment of an insect between the tergum and the sternum. The terms pro-, meso- and metapleuron The metathorax is the posterior of the three segments in the thorax of an insect, and bears the third pair of legs. Its principal sclerites ( exoskeletal plates) are the metanotum (dorsal), the metasternum (ventral), and the metapleuron (lateral) ... are used respectively for the pleura of the first, second and third thoracic segments.

Animal Coloration
Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible. There are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view. Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry, taking advantage of the warning coloration of another species. Some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion dazzle, confusing a predator's attack by moving a bold pattern rapidly. Some animals are coloured for physical protection, with pigments in the skin to protect against sunburn, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khambat
Khambhat (, ), also known as Cambay, is a city and the surrounding urban agglomeration in Anand district in the Indian state of Gujarat. It was once an important trading center, but its harbour gradually silted up, and the maritime trade moved to Surat. Khambat lies on an alluvial plain at the north end of the Gulf of Khambhat, noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambat. Khambat is known for its halvasan sweet, sutarfeni, akik stone and kites (patang), and for sources of oil and gas. Khambat is perhaps the only place in India where the Harappan craft of agate bead making is found in the living tradition. Surprisingly Khambat has no stone deposits; the craft has survived mainly through acquiring stones from the Rajpipla hills, about 200 km away from the city. In the folklore of Khambat, the beginning of the craft is attributed to Baba Ghor, a 1500 AD saint from Ethiopia ( Habash) who had led a large c ...

Kambojas
Kamboja ( sa, कम्बोज) was a kingdom of Iron Age India that spanned parts of South and Central Asia, frequently mentioned in Sanskrit and Pali literature. Eponymous with the kingdom name, the Kambojas were an Indo-Iranian people of the Kshatriya caste inhabiting the Kamboja Mahajanapada region, forming one of the sixteen nations that made up ancient India from the sixth to fourth centuries BCE during the second urbanisation period. Earlier, during the late Vedic age, the Kambojas had emerged as an important part of the Indo Aryan Vedic people with a prominent place among the Kshatriya tribes of the Mahabharata. While historical boundaries of the Kambojas are varied, scholarly accounts altogether place the northern and western borders in present-day Tajikistan and eastern Uzbekistan, with eastern borders in present-day Jammu and Kashmir, and southern borders in present-day Iran and southern Afghanistan. Etymology The name ''Kamboja'' may derive from ''Kam' ... [...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 ...

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 ...
