Triamyxa
''Triamyxa'' is an extinct genus of myxophagan beetle in the monotypic family Triamyxidae from the Carnian stage of Late Triassic, approximately 230 million years ago. It was found in the Keuper Claystone of Poland. The type species is ''T. coprolithica'' and it was identified from specimens found in the coprolite ZPAL AbIII/3520, likely belonging to the dinosauriform ''Silesaurus opolensis''. Because ''Triamyxa'' specimens were found inside coprolites, this may offer a new method of finding insect fossils aside from amber. It is currently the oldest known member of Myxophaga. It was interpreted as either the most basal member of Myxophaga, or a sister group to Hydroscaphidae The Hydroscaphidae are a small family of water beetles known commonly as skiff beetles. As of 2010, there are 23 species in the family. Several are recently described. These beetles are small, most under in length. They are tan to brown in col ....

Myxophaga Genera
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae. Description Myxophaga have several diagnostic features: the antennae are more or less distinctly clubbed with usually fewer than nine segments, mesocoxal cavities are open laterally and bordered by a mesepimeron and metanepisternum, the hind wings are rolled apically in the resting positions. Internally, they are characterised by the presence of six malpighian tubules and the testes are tube-like and coiled. Beetles of this suborder are adapted to feed on algae. Their mouthparts are characteristic in lacking galeae and having a mobile tooth on their left mandible. Taxonomy There are four extant families in the suborder Myxophaga divided between two superfamilies, containing about 65 described species, and at least one extinct family. Superfamily ...

Silesaurus Opolensis
''Silesaurus'' is a genus of silesaurid dinosauriform from the Late Triassic, of what is now Poland. Discovery Fossilized remains of ''Silesaurus'' have been found in the Keuper Claystone in Krasiejów near Opole, Silesia, Poland, which is also the origin of its name. The type species, ''Silesaurus opolensis'', was described by Jerzy Dzik in 2003. It is known from some 20 skeletons, making it one of the best-represented species of early dinosauriformes. Description ''Silesaurus'' measured approximately in length. Lightly built, it was probably a fast and agile animal with an active lifestyle. The snout was narrow with forward-pointing nostrils, and the large orbits likely provided ''Silesaurus'' with acute vision. Initially, ''Silesaurus'' was thought to be strictly herbivorous, but later research on coprolite contents indicates that it may have been insectivorous, feeding on insects such as the beetle '' Triamyxa''. The teeth of the animal were small, conical, and serrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keuper Claystone
The Keuper is a lithostratigraphic unit (a sequence of rock strata) in the subsurface of large parts of west and central Europe. The Keuper consists of dolomite, shales or claystones and evaporites that were deposited during the Middle and Late Triassic epochs (about ). The Keuper lies on top of the Muschelkalk and under the predominantly Lower Jurassic Lias or other Early Jurassic strata. The Keuper together with the Muschelkalk and the Buntsandstein form the Germanic Trias Group, a characteristic sequence of rock strata that gave the Triassic its name. "Muschelkalk (geology)", Britannica Online Encyclopedia, October 2010, webpage: EB-39 Exposure The Upper Triassic is well exposed in Swabia, Franconia, Alsace and Lorraine and Luxembourg; it extends from Basel on the east side of the Rhine into Hanover, and through England into Scotland and north-east Ireland; it appears flanking the central plateau of France and in the Pyrenees and Sardinia. The Keuper sequence is li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

Extinct Insects
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 last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever 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 animal species include non-avian dinosaurs, saber-toothed cats, dodos, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opole County
__NOTOC__ Opole County ( pl, powiat opolski) is a unit of territorial administration and local government (powiat) in Opole Voivodeship, south-western Poland. It came into being on January 1, 1999, as a result of the Polish local government reforms passed in 1998. Its administrative seat is the city of Opole, although the city is not part of the county (it constitutes a separate city county). The county contains four towns: Ozimek, east of Opole, Niemodlin, west of Opole, Prószków, south-west of Opole, and Tułowice, south-west of Opole. The county covers an area of . As of 2019 its total population is 123,487, out of which the population of Ozimek is 8,657, that of Niemodlin is 6,315, that of Tułowice is 4,011, that of Prószków is 2,570, and the rural population is 101,934. Neighbouring counties Apart from the city of Opole, Opole County is also bordered by Namysłów County and Kluczbork County to the north, Olesno County to the north-east, Strzelce County to the sout ...

Fossil Taxa Described In 2021
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 ...

Algal Mat
Algal mats are one of many types of microbial mat that forms on the surface of water or rocks. They are typically composed of blue-green cyanobacteria and sediments. Formation occurs when alternating layers of blue-green bacteria and sediments are deposited or grow in place, creating dark-laminated layers. Stromatolites are prime examples of algal mats. Algal mats played an important role in the Great Oxidation Event on Earth some 2.3 billion years ago. Algal mats can become a significant ecological problem, if the mats grow so expansive or thick as to disrupt the other underwater marine life by blocking the sunlight or producing toxic chemicals. Cyanobacteria forming algal mats Cyanobacteria found in sedimentary rocks indicate that bacterial life began on Earth during the Precambrian age. Fossilized cyanobacteria are commonly found in rocks that date back to Mesoproterozoic.BETTINA E. SCHIRRMEISTER, MURIEL GUGGER and PHILIP C. J. DONOGHUE (2015), CYANOBACTERIA AND THE GREAT OXIDA ...

Hydroscaphidae
The Hydroscaphidae are a small family of water beetles known commonly as skiff beetles. As of 2010, there are 23 species in the family. Several are recently described. These beetles are small, most under in length. They are tan to brown in color and the elytra are abbreviated, leaving several tapering tergites of the abdomen exposed. The wings are fringed with long setae. The larvae are fusiform, with a wide thorax and a narrowing abdomen. Hydroscaphidae live on mats of algae with a thin layer of running water. This may be the accumulated algae lining the very edge of a stream of water. They tolerate a wide range of temperatures; they have been observed in hot springs and in icy snowmelt. The algae are their food source. The reproductive cycle is not well known. In at least one species, the female lays a single large egg on the algal mat. Hydroscaphid species have been reported from every continent except Antarctica. Genera: * ''Hydroscapha'' LeConte, 1874 * '' Scaphydra'' R ...
