Electrinocellia
''Electrinocellia'' is an extinct monotypic genus of snakefly in the family Inocelliidae containing the single species ''Electrinocellia peculiaris'' and known from Eocene aged Baltic amber. History and classification The genus is known from only the holotype, a single dark brown male specimen, deposited in the Harvard University Museum of Comparative Zoology as specimen number 51. The specimen was first studied and described by the prolific paleoentomologist Dr. Frank M. Carpenter, while he was curator of the Harvard paleoentomological collections. The genus was named from the Latin ''electrum'' meaning "amber" and ''Inocellia'', the type genus for Inocelliidae. The species name ''peculiaris'' is a reference to the enigmatic nature of the species when first studied. When first described the species was placed in ''Inocellia'' as ''Inocellia peculiaris''. In his type description of the species, Dr. Carpenter noted a number of odd features which do not conform well with extant ...

Snakefly
Snakeflies are a group of Predation, predatory insects comprising the order (biology), order Raphidioptera with two extant families: Raphidiidae and Inocelliidae, consisting of roughly 260 species. In the past, the group had a much wider distribution than it does now; snakeflies are found in temperate regions worldwide but are absent from the tropics and the Southern Hemisphere. Recognisable representatives of the group first appeared during the Early Jurassic. They are a Relict (biology), relict group, having reached their apex of diversity during the Cretaceous before undergoing substantial decline. An adult snakefly resembles a lacewing in appearance but has a notably elongated thorax which, together with the mobile head, gives the group their common name. The body is long and slender and the two pairs of long, membranous wings are prominently veined. Females have a large and sturdy ovipositor which is used to deposit eggs in some concealed location. They are Holometabolism, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

Pterostigma
The pterostigma (plural: pterostigmata) is a group of specialized cells in the outer insect wing, wings of insects, which are often thickened or coloured, and thus stand out from other cells. It is particularly noticeable in dragonfly, dragonflies, but present also in other insect groups, such as snakefly, snakeflies, hymenopterans, and megalopterans. Purpose The pterostigma, a heavier section of the wing than nearby sections, assists in gliding. Without the pterostigmata, self-exciting vibrations known as aeroelastic flutter, flutter would set in on the wing above a certain critical speed, making gliding impossible. Tests show that with the pterostigmata, the critical gliding speed is increased 10–25% on one species of dragonfly. Pseudopterostigma Some female damselfly, damselflies in the family Calopterygidae possess a ''pseudopterostigma''. This is similar in location on the wing to a true pterostigma but is crossed by veins and is only defined by its paler colour compared ...

Prehistoric Insects Of Europe
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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Taxa Described In 1995
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 ...

Eocene Insects
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. 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 isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Psyche (entomological Journal)
''Psyche'' is a scientific journal of entomology which was established in 1874 by the Cambridge Entomological Club as a "journal for the publication of biological contributions upon Arthropoda from any competent person". The name of the journal is derived from the Ancient Greek word for butterfly. The journal has been published since 1874 (with gaps from 1886 to 1887, 1995 to 1999, and 2000 to 2007). In 2007 the Club transferred the journal to the Hindawi Publishing Corporation, and it became an open-access journal in 2008, with articles distributed online under the Creative Commons Attribution License. Almost all back issues were scanned and are available online as PDF files. History Samuel Hubbard Scudder proposed to start an "Organ of the Cambridge Entomological Club" at its fourth meeting. When ''Psyche'' began publication, its first editor was B. P. Mann. Its articles concentrated on general anatomy, biological entomology, and to set up a Bibliographic Record of all writin ...
