Issini
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea. Distribution Species of this family are present throughout the Northern Hemisphere. Description Issidae are small insects generally with a stocky body, as the wings mainly develop in width. Basic body coloration is not striking, usually shows brownish colors. The head has two ocelli. The forewings have strong pronounced ribs. They wrap the abdomen when the insect is at rest. The family originally included approximately 1000 species with 215 genera, but the systematics of Issidae remains uncertain, with many of the subfamilies having been recently removed to separate families, including Caliscelidae. Nogodinidae, and Tropiduchidae. In 2013, scientists described a biologically unique set of mechanical gears in an '' Issus'' nymph, though identical structures are known in most planthoppers, and were known for decades before the ...

Issus Coleoptratus
''Issus coleoptratus'' is a species of planthopper belonging to the family Issidae. Distribution and habitat This common species can be found in the western Palearctic realm, in the Near East, and in North Africa. These insects live on shrubbery and on foliage of various woody plants and common deciduous trees and in mixed forests (forest edges and parks).P.F. Whitehead & R.S. Ke/ref> Description ''Issus coleoptratus'' can reach a length of . The coloration of these planthoppers can vary from light brown and olive to nearly black. The head, including the eyes, is narrower than the pronotum. The forehead is usually dark brown to black in the upper third, with lighter spots. In the lower area it is greenish, yellowish or brownish. The leathery wings usually show a huge number of dark brown cross-veins with a dark brown discal spot and some evidence of banding. The forewing veins of males and females differs (sexual dimorphism), as they are effaced distally in the female, while in ...

Hemisphaerius
''Hemisphaerius'' is a genus of bugs in the family Issidae and tribe Hemisphaeriini. Species resemble the closely related ''Gergithus'': but are differentiated in this genus by the size of the frons Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insec ... and shorter legs.

Menat Formation
The Menat Formation is a geologic formation in France. It preserves fossils dating back to the Paleocene. It is a maar deposit located on top of an ancient volcano, the extent is very localised with the outcropping area being around 600 by 1000 metres. Numerous species of fossil insects, plants and fish are known, as well as some isolated mammals, including the primate '' Plesiadapis insignis'', the choristodere reptile ''Lazarussuchus'', and birds, including members of Halcyornithidae and Messelasturidae Messelasturidae is an extinct family of birds known from the Eocene of North America and Europe.

Gergithus
''Gergithus'' is a genus of planthoppers in the family Issidae. Like all planthoppers, adults feed on plant sap and are capable of escaping by leaping. The genus like other members in the tribe appears somewhat rounded and beetle-like, in some cases, with a mimetic resemblance to ladybird beetles. About 60 species are known in the genus and they are distributed in the Indomalayan and Palearctic Realms. Description The genus is closely related to '' Hemisphaerius'' but differs in having longer frons (forehead) and legs. The frons also lacks a median keel (carina) or tubercles on the frons, pronotum or mesonotum. The rounded tegmen which resembles the elytra An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alterna ... of beetles are often patterned.

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 ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). 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'', "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 Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 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 Popigai impact structure, Siberia and in what is now ...
