Permotanyderus
''Permotanyderus'' is an extinct genus of protodipteran insect of the Permotanyderidae family, first described by Edgar F. Riek in Australia in 1953 and which contains a single species ''P. ableptus''. Evidence of the presence of Diptera or their direct predecessors in the Upper Permian of Australia is shown by the presence of Mecoptera Mecoptera (from the Greek: ''mecos'' = "long", ''ptera'' = "wings") is an order of insects in the superorder Endopterygota with about six hundred species in nine families worldwide. Mecopterans are sometimes called scorpionflies after their lar ... in those formations. The Paratrichoptera of the Upper Permian probably, and those of the Triassic certainly, have been considered survivors of the maternal group. Riek described in 1953 two species of protodipteran of the Upper Permian of Australia: ''Permotanyderus ableptus'' and '' Choristotanyderus nanus'' joining '' Permotipula patricia'' named by Tillyard in 1929, but these cannot be attributed ...

Permotanyderidae
The Permotanyderidaea are an extinct family of insects within the order Protodiptera. Along with Permotipulidae (''Permotipula'' and ''Permila'', Willmann, 1989) and the Robinjohniidae (Robinjohnia, Scherbakov ET to., 1995), the somewhat more distantly related Permotanyderidae forms a group of mecopteroids of the Late Permian of Australia and Eurasia (250-260 Ma) that represents the older close relatives of the true flies. The first two genera had separate wings (presumably the front), while the last two have been created from complete specimens: The Robinjohniidae had four wings of about the same size, while the hind wings of the ''Choristotanyderus nanus'' (Permotanyderidae) specimens had a size of about half of the front, and the mesothorax was great. In all these genera the wing venation was low compared with other mecopteroids and close to the hypothetical original venation of the Diptera Flies are insects of the order Diptera, the name being derived from the Gre ...

Mecoptera
Mecoptera (from the Greek: ''mecos'' = "long", ''ptera'' = "wings") is an order of insects in the superorder Endopterygota with about six hundred species in nine families worldwide. Mecopterans are sometimes called scorpionflies after their largest family, Panorpidae, in which the males have enlarged genitals raised over the body that look similar to the stingers of scorpions, and long beaklike rostra. The Bittacidae, or hangingflies, are another prominent family and are known for their elaborate mating rituals, in which females choose mates based on the quality of gift prey offered to them by the males. A smaller group is the snow scorpionflies, family Boreidae, adults of which are sometimes seen walking on snowfields. In contrast, the majority of species in the order inhabit moist environments in tropical locations. The Mecoptera are closely related to the Siphonaptera (fleas), and a little more distantly to the Diptera (true flies). They are somewhat fly-like in appearance, ...

Choristotanyderus Nanus
''Choristotanyderus'' is an extinct, monotypic genus of protodipteran insect containing a single species, ''Choristotanyderus nanus'' which lived during the Permian period. The genus and species were first described by Edgar Frederick Riek in 1953 from a specimen found in New South Wales, Australia. It is considered a transitional form between Mecoptera and Diptera. The genus is placed in the protodipteran family Permotanyderidae with the related genus ''Permotanyderus''. Morphology ''Choristotanyderus'', despite being closely related to Diptera, retained four wings, with the hind wings being about one third as long as the forewings. These wings show the characteristic kink at the base of the R vein which is diagnostic of Diptera, but other venation patterns were more characteristic of Mecoptera Mecoptera (from the Greek: ''mecos'' = "long", ''ptera'' = "wings") is an order of insects in the superorder Endopterygota with about six hundred species in nine families worldwide. ...

Edgar F
Edgar is a commonly used English given name, from an Anglo-Saxon name ''Eadgar'' (composed of '' ead'' "rich, prosperous" and '' gar'' "spear"). Like most Anglo-Saxon names, it fell out of use by the later medieval period; it was, however, revived in the 18th century, and was popularised by its use for a character in Sir Walter Scott's '' The Bride of Lammermoor'' (1819). People with the given name * Edgar the Peaceful (942–975), king of England * Edgar the Ætheling (c. 1051 – c. 1126), last member of the Anglo-Saxon royal house of England * Edgar of Scotland (1074–1107), king of Scotland * Edgar Angara, Filipino lawyer * Edgar Barrier, American actor * Edgar Baumann, Paraguayan javelin thrower * Edgar Bergen, American actor, radio performer, ventriloquist * Edgar Berlanga, American boxer * Edgar H.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permotipula Patricia
''Permotipula'' is an extinct monotypic genus of protodipteran insect which contains a single species ''Permotipula patricia''. The only specimen of ''Permotipula'' was found in Late Permian strata of the Newcastle Coal MeasuresJell, Peter A. (2004"The fossil insects of Australia"''Memoirs of the Queensland Museum'' 50(1): pp. 1–124, page 2 between the towns of Belmont and Warners Bay on the eastern side of Lake Macquarie, New South Wales, Australia and named by Robert J. Tillyard in 1929. The specimen consisting of a single well preserved wing, was considered lost after the death of Tillyard in 1937. The loss of the specimen and the mention by Tillyard of a second insect fossil from the same site, later described as '' Robinjohnia tillyardi'' resulted in much confusion regarding the taxonomic affiliations of ''P. patricia''. ''Robinjohnia'', a four winged insect which is now placed in the order Mecoptera. The ''P. patricia'' type specimen was found in the Tillyard c ...

Fossil Taxa Described In 1953
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...
