Ostracod Genera
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 33,000 species (only 13,000 of which are extant) have been identified,Brandão, S.N.; Antonietto, L.S; Nery, D.G.; Santos, S.G.; Karanovic, I. (2023). World Ostracoda Database. Accessed at https://www.marinespecies.org/ostracoda on 2023-09-12. grouped into 7 valid orders. They are small crustaceans, typically around in size, but varying from , the latter in the case of the marine ''Gigantocypris.'' The largest known freshwater species is '' Megalocypris princeps'', which reach 8 mm in length. In most cases, their bodies are flattened from side to side and protected by a bivalve-like valve or "shell" made of chitin, and often calcium carbonate. The family Entocytheridae and many planktonic forms do not have calcium carbonate. The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on shell and soft part morpholog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoology, zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis.'' He published his first important work, , in 1796, and was eventually employed by the . His foresighted work on arthropod systematics and Taxonomy (biology), taxonomy gained him respect and accolades, including being asked to write the volume on insects for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomology, entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive-la-Gaillarde, Brive, then in the Limousin (province), province of Limousi ...

Baltic Amber
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for 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 and 400 tonnes in 2015. Baltic amber is also found in Poland, as well as the Baltic states. Bitterfeld amber from the brown coal mines near Bitterfeld in Germany was previously thought to be redeposited Baltic amber, but is now known to be chemically distinct, though like with Ukrainian Rovno amber, it is thought to have been deposited around the same time as Baltic amber. Because Baltic amber contains from 3 to 8% succinic acid, it is also termed succinite. Geologic context ''In situ'' Balt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Foraminifera
Foraminifera ( ; Latin for "hole bearers"; informally called "forams") are unicellular organism, single-celled organisms, members of a phylum or class (biology), class of Rhizarian protists characterized by streaming granular Ectoplasm (cell biology), ectoplasm for catching food and other uses; and commonly an external shell (called a "Test (biology), test") of diverse forms and materials. Tests of chitin (found in some simple genera, and ''Textularia'' in particular) are believed to be the most primitive type. Most foraminifera are marine, the majority of which live on or within the seafloor sediment (i.e., are benthos, benthic, with different sized species playing a role within the macrobenthos, meiobenthos, and Benthos, microbenthos), while a smaller number float in the water column at various depths (i.e., are planktonic), which belong to the suborder Globigerinina. Fewer are known from freshwater or brackish conditions, and some very few (nonaquatic) soil species have been id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A large amount of microfauna are soil microfauna which includes microbes, rotifers, and nematodes. These types of animal-like eukaryotic microbes and true animals are |
Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon. The Ordovician spans 41.6 million years from the end of the Cambrian Period Megaannum, Ma (million years ago) to the start of the Silurian Period Ma. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official per ...

Proceedings Of The Royal Society B
''Proceedings of the Royal Society'' is the main research journal of the Royal Society. The journal began in 1831 and was split into two series in 1905: * Series A: for papers in physical sciences and mathematics. * Series B: for papers in life sciences. Many landmark scientific discoveries are published in the Proceedings, making it one of the most important science journals in history. The journal contains several articles written by prominent scientists such as Paul Dirac, Werner Heisenberg, Ernest Rutherford, Erwin Schrödinger, William Lawrence Bragg, Lord Kelvin, J.J. Thomson, James Clerk Maxwell, Dorothy Hodgkin and Stephen Hawking. In 2004, the Royal Society began '' The Journal of the Royal Society Interface'' for papers at the interface of physical sciences and life sciences. History The journal began in 1831 as a compilation of abstracts of papers in the ''Philosophical Transactions of the Royal Society'', the older Royal Society publication, that began in 1665. ...

Derek E
Derek is a masculine given name. It is the English language short form of Diederik, the Low Franconian form of the name Theodoric. Theodoric is an old Germanic name with an original meaning of "people-ruler" or "lead the people". Common variants of the name are Derrek, Derik, Deryck (included here), as well as Derrick and Derick. History The English form of the name arises in the 15th century, via import from the Low Countries. The native English (Anglo-Saxon) form of the name was ''Deoric'' or ''Deodric'', from Old English ''Þēodrīc'', but this name had fallen out of use in the medieval period. During the Late Middle Ages, there was intense contact between the territories adjacent to the North Sea, in particular due to the activities of the Hanseatic League. As a result, there was a lot of cross-pollination between Low German, Dutch, English, Danish and Norwegian. The given name ''Derk'' is found in records of the Low Countries from the early 14th century, and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
