Phalangiotarbi
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, Phalangi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachnida
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult inse ...

Nemastomoides Depressus
''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.

Reginald Innes Pocock
Reginald Innes Pocock F.R.S. (4 March 1863 – 9 August 1947) was a British zoologist. Pocock was born in Clifton, Bristol, the fourth son of Rev. Nicholas Pocock and Edith Prichard. He began showing interest in natural history at St. Edward's School, Oxford. He received tutoring in zoology from Sir Edward Poulton, and was allowed to explore comparative anatomy at the Oxford Museum. He studied biology and geology at University College, Bristol, under Conwy Lloyd Morgan and William Johnson Sollas. In 1885, he became an assistant at the Natural History Museum, and worked in the section of entomology for a year. He was put in charge of the collections of Arachnida and Myriapoda. He was also given the task to arrange the British birds collections, in the course of which he developed a lasting interest in ornithology. The 200 papers he published in his 18 years at the museum soon brought him recognition as an authority on Arachnida and Myriapoda; he described between 300 and 400 s ...

Samuel Hubbard Scudder
Samuel Hubbard Scudder (April 13, 1837 – May 17, 1911) was an American entomologist and paleontologist. He was a leading figure in entomology during his lifetime and the founder of insect paleontology in America. In addition to fossil insects, he was an authority on butterflies (Lepidoptera) and grasshoppers (Orthoptera). Biography Scudder was born on April 13, 1837, in Boston, Massachusetts, the son of Charles Scudder and Sarah Lathrop (Coit) Scudder. His father was a successful merchant, and both parents had Puritan roots dating back to the founding of the Massachusetts Bay Colony in the 1620s. He was raised in a strict Calvinist Congregational household.Leach (2013) One of his younger brothers, Horace Scudder, became a noted author and editor of the ''Atlantic Monthly'',Cockerell (1911) while his niece Vida Dutton Scudder was a writer and social activist. Scudder attended Boston Latin School, and then enrolled in Williams College in 1853 at the age of 16. He studied with na ...
