Lachnus Quesneli
''Lachnus'' is a genus of aphids and the name-bearing type genus of the subfamily Lachninae Lachninae is a subfamily of the family Aphididae, containing some of the largest aphids, and they are sometimes referred to as "giant aphids". Members of this subfamily typically have greatly reduced cornicle The cornicle (or siphuncule) is o .... It consists of about 20 species.

Holcorpa Maculosa Allotype AMNH-FI-18887 NPS Img1
''Holcorpa'' is a genus of extinct insects in the scorpionfly order Mecoptera. Two Eocene age species found in Western North America were placed into the genus, ''H. dillhoffi'' and ''H. maculosa''. ''Holcorpa'' was the only known member of the extinct family Holcorpidae until 2017, when the Middle Jurassic member of the family, '' Conicholcorpa stigmosa'', was described. History and classification When first described ''Holcorpa'' was identified from a single fossil which is preserved as a compression fossil in fine shales of the Florissant Formation, Colorado. At the time of description, the Florissant formation was considered to be Oligocene in age. Further refinement of the formation's age using radiometric dating of sanidine crystals has resulted in an age of 34 million years old, which places the formation in the Eocene Chadronian stage. Adjustment to the stages of the Eocene placed the formation in the Priabonian as of 2010. The second species is known from a single fo ...

Scorpionfly
Mecoptera (from the Greek language, Greek: ''mecos'' = "long", ''ptera'' = "wings") is an Order (biology), order of insects in the superorder Holometabola 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 t ...

Holcorpidae
Holcorpidae is an extinct family of scorpionflies. It contains two genera, '' Conicholcorpa'' which is known from the Middle Jurassic Daohugou beds of Inner Mongolia, China, and '' Holcorpa,'' known from the Eocene of North America, including the McAbee Fossil Beds of British Columbia, and the Florissant Formation of Colorado. Members of this family are distinguished by their unusually long male genitalia, as well as characteristics of their wing venation. Both '' Miriholcorpa'' and '' Fortiholcorpa'' from the Middle Jurassic of China also have affinities to this family, but the incompleteness of their remains and differences from known holcorpids make their placement uncertain.

Florissant Formation
The Florissant Formation is a sedimentary geologic formation outcropping around Florissant, Teller County, Colorado. The formation is noted for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales. Based on argon radiometric dating, the formation is Eocene (approximately 34 million years old ) in age and has been interpreted as a lake environment. The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing a diatom bloom. As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls. Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils. The Florissant Fossil Beds National Monument is a national monument established to preserve and study the geology and history of the area. History The name ''Fl ...

Priabonian
The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. '' Priabona'', an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known. History and naming The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. Stratigraphic definition The base of the Priabonian Stage is at the first appearance of calcareous nannoplankton species '' Chiasmolithus oamaruensis'' (which forms the base of nanoplankton biozone NP18). An official GSSP was ratified in 2020, and was placed in the Alano di Piave section in Alano di Piave, Bellu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
