Glisachaemus
''Glisachaemus'' is an extinct monotypic genus of planthopper in the Cixiidae subfamily Cixiinae and at present, it contains the single species ''Glisachaemus jonasdamzeni''. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe. History and classification ''Glisachaemus jonasdamzeni'' is known only from one fossil, the holotype, number "No. 20067". It is a single male individual preserved in a clear yellow amber specimen with several unidentified Collembola associated and a parasitic mite on its dorsal surface. The specimen is complete, with only the right foreleg detached, but associated close by the body. The male was entombed while in flight posture, with both the hemelytra and hindwings spread. The amber is currently residing in the private collection of Jonas Damzen, Vilnius, Lithuania. The specimen is to be donated to the Museum of Amber Inclusions, University of Gdańsk in Gdańsk, Poland with the accession num ...

Cixiidae
The Cixiidae are a family of fulgoroid insects, one of many families commonly known as planthoppers, distributed worldwide and comprising more than 2,000 species from over 150 genera. The genera are placed into three subfamilies, Borystheninae, Bothriocerinae and Cixiinae with sixteen tribes currently accepted in Cixiinae. Description Cixiid species are typically comparatively small (body size less than a centimeter) and usually inconspicuous. The face is longer than wide and the head is narrower than the pronotum. The forewings are at least partly transparent and the veins bear minute setae. The hind tibiae end in a cluster of spines and may sometimes have spines along their length. Nymphs live underground, feeding on roots. Adults feed on herbs, shrubs and/or trees; some are polyphagous, while others are specialised on their host plants (monophagous). A couple of species are cavernicolous, feeding on roots in volcanic caves. Females occasionally bear impressive "wax tails ...

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 ...

Monotypic Hemiptera Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Fossil Taxa Described In 2007
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 ...

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] |
Extinct Hemiptera
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the Endling, last individual of the species, although the Functional extinction, capacity to breed and recover may have been lost before this point. Because a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. More than 99% of all species that ever Life, lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct a ...

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] |
Vertex (anatomy)
In arthropod and vertebrate anatomy, the vertex (or ''cranial vertex'') is the highest point of the head. In humans, the vertex is formed by four bones of the skull: the frontal bone, the two parietal bones, and the occipital bone. These bones are connected by the coronal suture between the frontal and parietal bones, the sagittal suture between the two parietal bones, and the lambdoid suture between the parietal and occipital bones. ''Vertex baldness'' refers to a form of male pattern baldness in which the baldness is limited to the vertex, resembling a tonsure. In childbirth, ''vertex birth'' refers to the common head-first presentation of the baby, as opposed to the buttocks-first position of a breech birth. In entomology, the color and shape of an insect's vertex and the structures arising from it are commonly used in identifying species. See also *Calvaria (skull) *Crown (anatomy) The crown is the top portion of the head behind the vertex. The anatomy of the crown varies ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
