Electrentomidae
Electrentomidae is an extinct family of barklice, booklice, and parasitic lice in the order Psocodea. There are about six genera and seven described species in Electrentomidae. The family was synonymsed with the extant family Manicapsocidae in 2003 without discussion, with a prior proposal in 1972, but Azar et al., 2017, stated that "we consider herein lectrentomidae and Manicapsocidaeapart, because a cladistic phylogenetic analysis is needed prior to taking such important decision for these groups." Genera These six genera belong to the family Electrentomidae: * † '' Electrentomum'' Enderlein, 1911 Baltic amber, Eocene * † '' Eomanicapsocus'' Nel, Prokop, De Ploeg & Millet, 2005 Oise amber, France, Ypresian *† '' Eoprotroctopsocus'' Nel, Prokop, De Ploeg & Millet, 2005 Oise amber, France, Ypresian *† '' Manicapsocidus'' Baz & Ortuño, 2001 Álava amber, Escucha Formation, Spain, Albian * † '' Paramesopsocus'' Azar, Hajar, Indary & Nel, 2009 Karabastau Formation, Kazak ...

Troctomorpha
Troctomorpha is one of the three major suborders of Psocodea (formerly Psocoptera)(barklice, booklice, and parasitic lice), alongside Psocomorpha and Trogiomorpha. There are more than 30 families and 5,800 described species in Troctomorpha. The order includes parasitic lice, which are most closely related to the booklice family Liposcelididae. Cladogram Cladogram showing the position of Troctomorpha within Psocodea: Fossil record The oldest record of the suborder is suggested to be '' Paramesopsocus adibi,'' known from the Late Jurassic Karabastau Formation of Kazakhstan. Classification Troctomorpha contains the following subgroups: * Infraorder: Amphientometae ** Family: Amphientomidae Enderlein, 1903 (tropical barklice) ** Family: Compsocidae Mockford, 1967 ** Family: Electrentomidae Enderlein, 1911 ** Family: Manicapsocidae Mockford, 1967 ** Family: Musapsocidae Mockford, 1967 ** Family: Protroctopsocidae Smithers, 1972 ** Family: Troctopsocidae Mockford, 1967 * ...

Manicapsocidae
Manicapsocidae is a family of Psocodea (formerly Psocoptera). It contains 8 extant species in 4 genera, with most of the species being found in the Neotropics, with one species in the Afrotropics. The extinct family Electrentomidae has been suggested to be a synonym of this family, though this has been considered premature by other scholars in the absence of cladistic analysis. Confirmed fossil species of the family are nearly as numerous as living ones, extending back to the Mid-Cretaceous.

Psocodea
Psocodea is a taxonomic group of insects comprising the bark lice, book lice and parasitic lice. It was formerly considered a superorder, but is now generally considered by entomologists as an order. Despite the greatly differing appearance of parasitic lice (Phthiraptera), they are believed to have evolved from within the former order Psocoptera, which contained the bark lice and book lice, now found to be paraphyletic. They are often regarded as the most primitive of the hemipteroids. Psocodea contains around 11,000 species, divided among four suborders and more than 70 families. They range in size from 1–10 millimetres (0.04–0.4 in) in length. The species known as booklice received their common name because they are commonly found amongst old books—they feed upon the paste used in binding. The barklice are found on trees, feeding on algae and lichen. Anatomy and biology Psocids are small, scavenging insects with a relatively generalized body plan. They feed pr ...

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 ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''. Regional equivalents The Barremian falls in the Gallic epoch, a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lebanese Amber
Lebanese amber is fossilized resin found in Lebanon and southwest Syria. It dates back approximately 130-125 million years to the Barremian of the Early Cretaceous. It formed on what was then the northern coast of Gondwana, believed to be a tropical or subtropical zone in a temperate or hot climate. It is the oldest source of amber with a significant number of inclusions. Up to 300 sources of Lebanese amber have been recovered and 17 of them are important sources of organic inclusions, which are the oldest of their kind. The inclusions help to document Cretaceous fauna and flora. Origins Lebanese amber can be found in Lebanon and neighboring areas of Syria and north Palestine. Up to 300 different sources of amber had been discovered by 2010. The amber was deposited in the Cretaceous era and is rich in fossil synclusions. 19 of the discovered sources are rich in inclusions from the Early Cretaceous. All of them are located in Lebanon, which makes it the largest source of inclusion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callovian
In the geologic timescale, the Callovian is an age and stage in the Middle Jurassic, lasting between 166.1 ± 4.0 Ma (million years ago) and 163.5 ± 4.0 Ma. It is the last stage of the Middle Jurassic, following the Bathonian and preceding the Oxfordian. Stratigraphic definitions The Callovian Stage was first described by French palaeontologist Alcide d'Orbigny in 1852. Its name derives from the latinized name for Kellaways Bridge, a small hamlet 3 km north-east of Chippenham, Wiltshire, England. The base of the Callovian is defined as the place in the stratigraphic column where the ammonite genus ''Kepplerites'' first appears, which is the base of the biozone of '' Macrocephalites herveyi''. A global reference profile (a GSSP) for the base had in 2009 not yet been assigned. The top of the Callovian (the base of the Oxfordian) is at the first appearance of ammonite species '' Brightia thuouxensis''. Subdivision The Callovian is often subdivided into three substages ( ...

Escucha Formation
The Escucha Formation is a geological formation in La Rioja and Teruel provinces of northeastern Spain whose strata date back to the late Aptian to middle Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, et al., 2004 The approximately thick formation underlies the Utrillas Formation and overlies Castrillo de la Reina, Benassal & Oliete Formations. The Escucha Formation comprises siltstones, mudstones, sandstones, coal, siltstones and amber, in which several fossil insects were found. The formation was deposited in a variety of continental to paralic (deltaic) environments.Peyrot et al., 2007 Fossil content The Escucha Formation has provided the following fossils, among others: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
