Choristotanyderus
''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 . The third thorax segment was also reduced, which has been considered another intermediate feature between the Mecoptera and the Diptera . References † A dagge ...

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 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 .... 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, an ...

Mecoptera
Mecoptera (from the Greek language, Greek: ''mecos'' = "long", ''ptera'' = "wings") is an Order (biology), order of insects in the superorder Endopterygota with about six hundred species in nine Family (biology), 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 Rostrum (anatomy), 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 ...

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 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 to any of the sub-groups of the dipterans or their direct predecessors.

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] |
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 ...

Permian Insects
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 amphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Insect Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Insect Genera
In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Proceedings Of The Linnean Society Of New South Wales
The Linnean Society of New South Wales promotes ''the Cultivation and Study of the Science of Natural History in all its Branches'' and was founded in Sydney, New South Wales (Australia) in 1874 and incorporated in 1884. History The Society succeeded the ''Entomological Society of New South Wales'', founded in 1862 which folded in 1872, with James Charles Cox as its first president. The first issue of ''Proceedings'' was in 1875. The establishment of the Society was largely due to the dedication and financial support of its first President, Sir William Macleay. Joseph James Fletcher was director and librarian (this title was afterwards changed to secretary) from 1885 and edited 33 volumes of the ''Proceedings'' of the society. In September 1882, a fire destroyed the library and a part of the scientific material of the society. The efforts of William Macleay made it possible nevertheless for the society to continue its activities. Macleay bursary In 1903, the Society created ...

National Center For Science Education
The National Center for Science Education (NCSE) is a not-for-profit membership organization in the United States whose stated mission is to educate the press and the public on the scientific and educational aspects of controversies surrounding the teaching of evolution and climate change, and to provide information and resources to schools, parents, and other citizens working to keep those topics in public school science education. Based in Oakland, California, it claims 4,500 members that include scientists, teachers, clergy, and citizens of varied religious and political affiliations. The Center opposes the teaching of religious views in science classes in America's public schools; it does this through initiatives such as Project Steve. The Center has been called the United States' "leading anti-creationist organization". The Center is affiliated with the American Association for the Advancement of Science.

Edgar Frederick Riek
Edgar Frederick Riek (1920–2016) was an Australian entomologist and invertebrate zoologist known for his research on fossil insects and the taxonomy of freshwater crayfish. He later became known as prominent viticulturist and winemaker. Affiliated with the CSIRO for over 30 years, he wrote the first pocket field guide to Australian insects, described over 230 species, and is commemorated in the names of over 80 species. After retiring from the CSIRO he became a noted figure in the Australian wine industry, co-founding the Canberra and District Vignerons Association and receiving the Order of Australia Medal (1996) for his work. Edgar Riek was born 1 May 1920 in Napier, New Zealand, to Australian parents. He was raised in Caboolture, Queensland, attended Brisbane Grammar School, and entered the University of Queensland in 1939 where he worked as an assistant in the Geology Department.
