Ogygiocarella
''Ogygiocarella'' Harrington and Leanza, 1957, is a genus of asaphid trilobites that lived during the Middle Ordovician Period. Etymology The generic name, ''Ogygiocarella'', refers to "Ogygia", the seventh daughter of Amphion and Niobe, which name is combined with "-care-", from the Greek "akares", meaning short, and finally "-ella", the diminutive form. History ''Ogygiocarella'' is arguably the first trilobite that was scientifically described. Rev. Edward Lhwyd published in 1698 in The Philosophical Transactions of the Royal Society, the oldest scientific journal in the English language, part of his letter “Concerning Several Regularly Figured Stones Lately Found by Him", that was accompanied by a page of etchings of fossils. One of his etchings figured a trilobite he found near Llandeilo, probably on the grounds of Lord Dynefor's castle, he described as “… the skeleton of some flat Fish …".

Trilobite
Trilobites (; meaning "three-lobed entities") are extinction, extinct marine arthropods that form the class (biology), class Trilobita. One of the earliest groups of arthropods to appear in the fossil record, trilobites were among the most successful of all early animals, existing in oceans for almost 270million years, with over 22,000 species having been described. Because trilobites had wide diversity and an easily fossilized mineralised exoskeleton made of calcite, they left an extensive fossil record. The study of their fossils has facilitated important contributions to biostratigraphy, paleontology, evolution, evolutionary biology, and plate tectonics. Trilobites are placed within the clade Artiopoda, which includes many organisms that are morphologically similar to trilobites, but are largely unmineralised. The relationship of Artiopoda to other arthropods is uncertain. Trilobites evolved into many ecological niches; some moved over the seabed as predators, scavengers, or ...

Asaphidae
Asaphidae is a family of asaphid trilobites. Although the first genera originate in Upper Cambrian marine strata, the family becomes the most widely distributed and most species-rich trilobite family during the Ordovician. 754 species assigned to 146 genera are included in Asaphidae. Distribution Most Asaphinae are characteristic of Baltica. Isotelinae genera are concentrated in Laurentia. The genera of Nobiliasaphinae are distributed in tropical Gondwana and South China. The genera of Ogygiocaridinae occur in Avalonia, Gondwana and Baltica. Asaphidae asaphids were already fairly common during the Upper-Cambrian, when 14 genera are known from Australia, North- and South-China. The last members of the family died-out at the end of the Ordovician. Assigned genera Asaphidae contains the following genera: *'' Anataphrus'' *'' Araiocaris'' *'' Asaphellus'' *''Asaphus'' *'' Atopasaphus'' *'' Aulacoparia'' *'' Aulacoparina'' *'' Australopyge'' *'' Baltiites'' *'' Banqiaoites' ...

Meadowtown
Meadowtown is a hamlet in west Shropshire, England, in the civil parish of Worthen with Shelve. Neighbouring hamlets include Marton, Ox Wood, Crest Wood, and Rorrington. Meadowtown contains a Site of Special Scientific Interest according to the U.K. government. A long-disused quarry in the hamlet is "a well known fossil collecting locality and has yielded typical and distinctive trilobites including Oxygiocarella debuchi, Marrolithus craticulatus, Lloydolithus lloydii and Oxyginus cordensis novenarius. Species of the brachiopod genus Dalmanella and occasional sponge spicule Spicules are structural elements found in most sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. Sponge spicules are made of calcium carbo ...s also occur." Meadowtown is also home to "Mammoth", a cow made famous on the internet involving a UK milk-price dispute in 2017. References Ha ...

Philosophical Transactions Of The Royal Society
''Philosophical Transactions of the Royal Society'' is a scientific journal published by the Royal Society. In its earliest days, it was a private venture of the Royal Society's secretary. It was established in 1665, making it the second journal in the world exclusively devoted to science, after the '' Journal des sçavans'', and therefore also the world's longest-running scientific journal. It became an official society publication in 1752. The use of the word ''philosophical'' in the title refers to natural philosophy, which was the equivalent of what would now be generally called ''science''. Current publication In 1887 the journal expanded and divided into two separate publications, one serving the physical sciences ('' Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences'') and the other focusing on the life sciences ('' Philosophical Transactions of the Royal Society B: Biological Sciences''). Both journals now publish theme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asaphida Genera
Asaphida is a large, morphologically diverse order of trilobites found in marine strata dated from the Middle Cambrian until their extinction during the Silurian. Asaphida contains six superfamilies (Anomocaroidea, Asaphoidea, Cyclopygoidea, Dikelocephaloidea, Remopleuridoidea and Trinucleioidea), but no suborders. Asaphids comprise some 20% of described fossil trilobites. In 2020, the superfamily Trinucleioidea was proposed to be raised to an order ( Trinucleida) and removed from Asaphida. Morphology The Asaphids generally have cephalon (head) and pygidium (tail) parts similar in size, and most species have a prominent median ventral suture. Heads are often flat, and carapace furrows in the head area are often faint or not visible. Thoracic segments typically number 5 - 12, though some species have as few as two and some as many as 30. They also generally have a wide doublure, or rim, that surrounds the cephalon. This causes some specimens to be described as having a charact ...

Flatfish Lhwyd
A flatfish is a member of the ray-finned demersal fish suborder Pleuronectoidei, also called the Heterosomata. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. The most primitive members of the group, the threadfins, do not resemble the flatfish but are their closest relatives. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Due to their highly distinctive morphology, flatfishes were previously treated as belonging to their own order, Pleuronectiformes. However, more recent taxonomic studies have found them to group within a diverse group of nektonic marine fishes known as the Carangiformes, which also includes jacks and billfish. Specifically, flatfish are mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llandeilo
Llandeilo () is a town and Community (Wales), community in Carmarthenshire, Wales, situated where the River Towy is crossed by the A483 road, A483 on a 19th-century stone bridge. At the 2021 United Kingdom census, 2021 census the community had a population of 1,784. It is adjacent to the westernmost point of the Brecon Beacons National Park.

Niobe
Niobe (; : Nióbē) was in Greek mythology a daughter of Tantalus and of either Dione or of Eurythemista or Euryanassa. She was the wife of Amphion and the sister of Pelops and Broteas. Niobe is mentioned by Achilles in Homer's ''Iliad'', which relates her ''hubris'', for which she was punished by Leto, who sent Apollo and Artemis to slay all of her children, after which her children lay unburied for nine days while she abstained from food. Once the gods had interred the slain, Niobe retreated to her native Sipylus, "where Nymphs dance around the River Acheloos, and though turned to stone, she broods over the sorrows sent by the Gods". Later writers asserted that Niobe was wedded to Amphion, one of the twin founders of Thebes, where there was a single sanctuary where the twin founders were venerated, but no shrine to Niobe. Mythology Family Her father was the ruler of a city located near Manisa in today's Aegean Turkey that was called "Tantalis" or "the city ...

Diminutive
A diminutive is a word obtained by modifying a root word to convey a slighter degree of its root meaning, either to convey the smallness of the object or quality named, or to convey a sense of intimacy or endearment, and sometimes to belittle something or someone. A ( abbreviated ) is a word-formation device used to express such meanings. A is a diminutive form with two diminutive suffixes rather than one. Purpose Diminutives are often employed as nicknames and pet names when speaking to small children and when expressing extreme tenderness and intimacy to an adult. The opposite of the diminutive form is the augmentative. In some contexts, diminutives are also employed in a pejorative sense to denote that someone or something is weak or childish. For example, one of the last Western Roman emperors was Romulus Augustus, but his name was diminutivized to "Romulus Augustulus" to express his powerlessness. Formation In many languages, diminutives are word forms that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
