Nemastomoides Elaveris
''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. (2007): Paleontology. In: Pinto-da-Rocha ''et al.'' 2007: 255 While the Nemastomoididae are currently included in the harvestman suborder Dyspnoi, they look more like Eupnoi.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Harvestmen
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of 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 phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Altho ...

Carboniferous Arthropods
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("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. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lineages ...

Treatise On Invertebrate Palaeontology
The ''Treatise on Invertebrate Paleontology'' (or ''TIP'') published by the Geological Society of America and the University of Kansas Press, is a definitive multi-authored work of some 50 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, every so often, previously published volumes of the ''Treatise'' are revised. Evolution of the project Raymond C. Moor ...

Eupnoi
The Eupnoi are a suborder of harvestmen, with more than 200 genera, and about 1,700 described species. They consist of two superfamilies, the Phalangioidea with many long-legged species common to northern temperate regions, and the small group Caddoidea, which have prominent eyes and spiny pedipalps. (2007): Morphology and Functional Anatomy. In: Pinto-da-Rocha ''et al.'' 2007: 17f Examples of this suborder include ''Hadrobunus grandis'' (Sclerosomatidae), ''Phalangium opilio'' and ''Dicranopalpus ramosus'' (Phalangiidae). Distribution Caddoidea are mostly found in temperate zones of both hemispheres; however, they are known from the Palearctic only from Japan, and from Baltic amber (about 40 million years old). One species known from Japan is also found in North America, where several more species are found. Other species occur in Southern South America, Venezuela, New Zealand and Australia. Neopilionidae show a Gondwanan distribution, with species found in South America, Sout ...

Phalangiotarbida
Phalangiotarbi ( Haase, 1890) is an extinct arachnid order first recorded from the Early Devonian of Germany and most widespread in the Upper Carboniferous coal measures of Europe and North America. The last species are known from the early Permian Rotliegend of Germany. The affinities of phalangiotarbids are obscure, with most authors favouring affinities with Opiliones (harvestmen) and/or Acari (mites and ticks). Phalangiotarbida has been recently (2004) proposed to be sister group to (Palpigradi+Tetrapulmonata): the taxon Megoperculata sensu Shultz (1990). ''Nemastomoides depressus'', described as a harvestman in the family Nemastomoididae, is actually a poorly preserved phalangiotarbid.Dunlop ''in'' Pinto-da-Rocha ''et al.'' 2007: 255 Names The order is also called Phalangiotarbida, the ending -ida originated when Petrunkevitch (1955) tried to standardize the endings of the arachnid orders, which is unnecessary and unwarranted according to the ICZN. Nevertheless, Phalangio ...

Mazon Creek
The Mazon Creek fossil beds are a conservation ' found near Morris, in Grundy County, Illinois. The fossils are preserved in ironstone concretions, formed approximately in the mid- Pennsylvanian epoch of the Carboniferous period. These concretions frequently preserve both hard and soft tissues of animal and plant materials, as well as many soft-bodied organisms that do not normally fossilize. The quality, quantity and diversity of fossils in the area, known since the mid-nineteenth century, make the Mazon Creek ' important to paleontologists, in attempting to reconstruct the paleoecology of the sites. The locality was declared a National Historic Landmark in 1997..   Geology The Mazon Creek fossils are found in the Upper Carboniferous Francis Creek Shale; the type locality is the Mazon River (or Mazon Creek), a tributary of the Illinois River near Morris, Grundy County, Illinois. The 25 to 30 meters of shale were formed approximately , during the Pennsylvanian period. ...

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. 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 historically had important foundries and forges. Science Charles Brongniart discovered many fossils near Commentry, including ''Meganeura'' in the Ste ...
