Ainigmapsychops
''Ainigmapsychops'' is an extinct genus of lacewing in the silky lacewing family Psychopsidae. The genus is solely known from an Eocene fossil found in North America. At the time of its description the new genus was composed of a single species, ''Ainigmapsychops inexspectatus''. History and classification ''Ainigmapsychops inexspectatus'' is known only from one fossil, the part side of the holotype, specimen number SRUI 99-96-76, which is housed in the collections of the Stonerose Interpretive Center in Republic, Washington. The specimen is preserved as a compression fossil in silty yellow to grayish shale, which was recovered from outcrops of the Tom Thumb Tuff member of the Klondike Mountain Formation. The formation is approximately Early Eocene, Ypresian in age, being radiometrically dated as . ''Ainigmapsychops'' was first studied by the paleoentomologists Vladimir N. Makarkin of the Far Eastern Branch of the Russian Academy of Sciences and S. Bruce Archibald from Sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klondike Mountain Formation
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs. The formation is the youngest in a group of formations which belong to the Challis Sequence rocks. The formation unconformably overlies rocks of the Eocene Sanpoil Volcanics and much older Triassic and Permian formations. The formation is bounded on its edges by a series of high-angle strike slip faults, which have contained the Klondike Mountain Formation in a series of graben structures, such as the Republic Graben. Public access to a fossiliferous outcrop at the north end of Republic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychopsidae
Psychopsidae is a family of winged insects of the order Neuroptera. They are commonly called silky lacewings. The silky lacewings are distinguishable in their adult stage by their spectacularly patterned and pubescent wings, broad wing shape, dense venation, and the presence of a ''vena triplica'' (the apical fusion of three veins in the hindwing).Grimaldi, D. and M. S. Engel. 2005. Evolution of Insects. Cambridge University Press, New York. Taxonomy They were formerly placed in the superfamily Hemerobioidea, but do not seem to be closely related to these net-winged insects at all. Rather, might be closer to the Myrmeleontoidea which contain for example the antlions (Myrmeleontidae). In particular, the spoon-winged laceflies (Nemopteridae) seem to be very closely related to the silky lacewings. These had at one time been placed in a superfamily Nemopteroidea. The fossil family Osmylopsychopidae was - as indicated by their scientific name - initially believed to be intermediate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ypresian
In the geologic timescale the Ypresian is the oldest age or lowest 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 Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones. The Ypresian shares its name with the Belgian Ieper Group (French: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular wiktionary:en:specimen, 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 (mathematics), 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 ...

Fossil Taxa Described In 2014
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 ...

Myrmeleontiformia
Myrmeleontiformia is an insect clade in the order Neuroptera, and which was historically treated as a suborder. The phylogeny of the Neuroptera has been explored using mitochondrial DNA sequences, and while issues remain for the order as a whole, such as "Hemerobiiformia" being paraphyletic, Myrmeleontiformia is generally agreed to be monophyletic, with one study giving the following cladogram: Superfamilies and families Clade Myrmeleontiformia * Superfamily Myrmeleontoidea (syn Nemopteroidea) ** Family Ascalaphidae: owlflies (possibly in Myrmeleontoidea) ** Family † Babinskaiidae ** Family Myrmeleontidae: antlions (includes Palaeoleontidae) ** Family Nemopteridae: spoonwings etc (formerly in Myrmeleontoidea) ** Family Nymphidae: split-footed lacewings (includes Myiodactylidae) ** Family † Rafaelianidae * Superfamily Psychopsoidea ** Family † Aetheogrammatidae ** Family †Kalligrammatidae Kalligrammatidae, sometimes known as kalligrammatids or kalligrammatid l ...

Osmylidae
Osmylidae are a small family of winged insects of the net-winged insect order Neuroptera. The osmylids, also called lance lacewings, stream lacewings or giant lacewings, are found all over the world. There are around 225 extant species. Description and ecology Adult osmylids are small to moderately-sized net-winged insects, with wingspans ranging from 1.4 to 3 cm. Smaller members resemble typical green lacewings, and larger species resemble antlions. Many species, namely those of the type genus '' Osmylus'', have spotted wings. The thin antennae are short. They have two compound eyes, as well as three ocelli in between. Adult osmylids, like green lacewings (some of which are colloquially known as "stinkflies"), have prothoracal glands which produce foul-smelling compounds used to deter would-be predators. Their larvae are superficially similar to those of spongillaflies (Sisyridae). They have peculiar mouthparts which look like a thin forceps with the ends bending outwards ...

Neuroptera
The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order consists of some 6,000 species. Neuroptera can be grouped together with the Megaloptera and Raphidioptera in the unranked taxon Neuropterida (once known as Planipennia) including: alderflies, fishflies, dobsonflies, and snakeflies. Adult Neuropterans have four membranous wings, all about the same size, with many veins. They have chewing mouthparts, and undergo complete metamorphosis. Neuropterans first appeared during the Permian period, and continued to diversify through the Mesozoic era. During this time, several unusually large forms evolved, especially in the extinct family Kalligrammatidae, often called "the butterflies of the Jurassic" for their large, patterned wings. Anatomy and biology Neuropterans are soft-bodied insects with relatively few specialized features. They have large lateral compound eyes, and may or may not also have ocel ...

Serendipity
Serendipity is an unplanned fortunate discovery. Serendipity is a common occurrence throughout the history of product invention and scientific discovery. Etymology The first noted use of "serendipity" was by Horace Walpole on 28 January 1754. In a letter he wrote to his friend Horace Mann, Walpole explained an unexpected discovery he had made about a lost painting of Bianca Cappello by Giorgio Vasari by reference to a Persian fairy tale, '' The Three Princes of Serendip''. The princes, he told his correspondent, were "always making discoveries, by accidents and sagacity, of things which they were not in quest of." The name comes from '' Serendip'', an old Persian name for Sri Lanka (Ceylon), hence ''Sarandib'' by Arab traders. It is derived from the Sanskrit ''Siṃhaladvīpaḥ'' (Siṃhalaḥ, Sri Lanka + dvīpaḥ, island). The word has been exported into many other languages, with the general meaning of "unexpected discovery" or "fortunate chance". Applications Inven ...

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 ...
