Eotrogulus
''Eotrogulus'' is an extinct genus of harvestmen known from the Carboniferous fossil record. The genus is the only member of the family Eotrogulidae and contains one species ''Eotrogulus fayoli''. ''Eotrogulus'' was found in the Coal Measures of Commentry in northern France, together with '' Nemastomoides elaveris''. ''Eotrogulus'' was previously thought to be a trigonotarbid The Order (biology), order Trigonotarbida is a group of extinct arachnids whose fossil record extends from the late Silurian to the early Permian (Pridoli epoch, Pridoli to Sakmarian).Dunlop, J.

Nemastomoides
''Nemastomoides'' is an extinct genus of harvestmen known from the Carboniferous fossil record. The genus is the only member of the family Nemastomoididae and contains three described species. ''Nemastomoides elaveris'' was found in the Coal Measures of Commentry in northern France, together with '' Eotrogulus fayoli''. Alexander Petrunkevitch described two fossil harvestmen from Mazon Creek, Illinois, United States, in 1913 in the genus ''Protopilio'', but later synonymized the two with the genus ''Nemastomoides''. While ''N. longipes'' is a harvestman with long legs and a segmented oval body, ''N. depressus'' is in reality not a harvestman, but a poorly preserved phalangiotarbid.Dunlop, Jason A.

Opiliones
The Opiliones (formerly Phalangida) are an Order (biology), order of arachnids, Common name, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs (see below). , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant taxon, extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their Phylogenetics, phylogenetic position within the Arachnida is disputed; their closest relatives may be camel spiders (Solifugae ...

Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Carboniferous Arthropods
The Carboniferous ( ) is a geologic period and system of the Paleozoic era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian and the later Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the period during which both terrestrial animal and land plant life was well established. Stegocephalia (four-limbed vertebrates including true tetrapods), whose forerunners (tetrapodomor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treatise On Invertebrate Palaeontology
The ''Treatise on Invertebrate Paleontology,'' published from 1953–2007 by the Geological Society of America and the University of Kansas, then 2009–present by the University of Kansas Paleontological Institute, is a definitive multi-authored work of currently 55 volumes, written by more than 300 paleontologists, and covering every phylum, class, order, family, and genus of fossil and extant (still living) invertebrate animals. The prehistoric invertebrates are described as to their taxonomy, morphology, paleoecology, stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing. Publication of the decades-long ''Treatise on Invertebrate Paleontology'' is a work-in-progress; and therefore it is not yet complete: For example, there is no volume yet published regarding the post-Paleozoic era caenogastropods (a molluscan group including the whelk and periwinkle). Furthermore, when needed, previously published volumes o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigonotarbida
The order Trigonotarbida is a group of extinct arachnids whose fossil record extends from the late Silurian to the early Permian ( Pridoli to Sakmarian).Dunlop, J. A., Penney, D. & Jekel, D. 2020A summary list of fossil spiders and their relatives In World Spider Catalog. Natural History Museum Bern, online at http://wsc.nmbe.ch , version 20.5 These animals are known from several localities in Europe and North America, as well as a single record from Argentina. Trigonotarbids can be envisaged as spider-like arachnids, but without silk-producing spinnerets. They ranged in size from a few millimetres to a few centimetres in body length and had segmented abdomens (opisthosoma), with the dorsal exoskeleton ( tergites) across the backs of the animals' abdomens, which were characteristically divided into three or five separate plates. Probably living as predators on other arthropods, some later trigonotarbid species were quite heavily armoured and protected themselves with spines and tub ...

Commentry
Commentry (; Auvergnat: ''Comentriac'') is a commune in the department of Allier in central France. It lies southwest of Moulins in the valley of the Œil. It is within 8 km of one of the geographic centres of France. The film actress Yvonne Rozille (1900–1985) was born in Commentry. Population History Commentry was home to Compagnie de Commentry-Fourchambault-Decazeville, thanks to an important coal deposit. The coal mine fueled a huge growth in population, from under 1,000 to more than 12,000, while Stéphane Mony was its CEO (1840–1884). Commentry was the first commune ever to elect a socialist mayor: Christophe Thivrier was elected 6 June 1882. During the repression of January and February 1894, the police conducted raids targeting the anarchists living there, without much success. The Socialist Party of France was founded in Commentry in September 1902. Economy Commentry gave its name to a coal field over 21 square kilometres in extent, and histo ...
