Timeline Of Eurypterid Research
This timeline of eurypterid research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, and taxonomic revisions of eurypterids, a group of extinct aquatic arthropods closely related to modern arachnids and horseshoe crabs that lived during the Paleozoic Era. The scientific study of eurypterids began in the early 19th century when James E. DeKay recognized a fossil that had previously been described as that of a fish as arthropod in nature. Though DeKay erroneously believed the fossil to represent a crustacean and a missing link between trilobites and branchiopods, the fossil became the type species of first ever eurypterid to be scientifically described, ''Eurypterus remipes'', in 1825.Clarke, J. K., Ruedemann R. (1912) " The Eurypterida of New York" Over 250 species of eurypterids in 74 recognized valid genera have been described since the discovery of ''Eurypterus remipes''. The most recent genus to be described is '' Terropte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Eurypterida Of New York Figure 1
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Eurypterus Paleoart
''Eurypterus'' ( ) is an extinct genus of eurypterid, a group of organisms commonly called "sea scorpions". The genus lived during the Silurian period, from around 432 to 418 million years ago. ''Eurypterus'' is by far the most well-studied and well-known eurypterid. ''Eurypterus'' fossil specimens probably represent more than 95% of all known eurypterid specimens. There are fifteen species belonging to the genus ''Eurypterus'', the most common of which is ''E. remipes'', the first eurypterid fossil discovered and the state fossil of New York. Members of ''Eurypterus'' averaged at about in length, but the largest individual discovered was estimated to be long. They all possessed spine-bearing appendages and a large paddle they used for swimming. They were generalist species, equally likely to engage in predation or scavenging. Discovery The first fossil of ''Eurypterus'' was found in 1818 by S. L. Mitchill, a fossil collector. It was recovered from the Bertie Formation ...

Samuel Hibbert-Ware
Samuel Hibbert-Ware (21 April 1782 – 30 December 1848), born Samuel Hibbert in St Ann's Square Manchester, was an English geologist and antiquarian. Life He was the eldest son of Samuel Hibbert (d.1815), a linen yarn merchant, and his wife Sarah Ware, from Dublin. Hibbert was granted an MD and became a Fellow of the Royal Society of Edinburgh. He served as the secretary of the Society of Scottish Antiquarians, a member of the Royal Medical and Wernerian Societies of Edinburgh, as well as a member of the Philosophical Society of Manchester. His book ''Sketches of the Philosophy of Apparitions'' (1825) is an early skeptical work that gave possible physical and physiological explanations for sightings of ghosts. He died at Hale Barns, Altrincham in Cheshire on 30 December 1848. He is buried in Ardwick cemetery in Manchester.

John Scouler
John Scouler (31 December 1804 – 13 November 1871) was a Scottish naturalist. Life Scouler, the son of a calico-printer, was born in Glasgow on 31 December 1804. He received the rudiments of his education at Kilbarchan, but was sent very early to the University of Glasgow. When his medical course there was completed, he went to Paris and studied at the Jardin des Plantes. On moving to England, Dr. (afterwards Sir) William Jackson Hooker secured for him an appointment as surgeon and naturalist on board the Hudson's Bay Company's ship ''William and Ann''. The vessel sailed from London on 25 July 1824 for the Columbia River, touching at Madeira, Rio de Janeiro and the Galapagos. His companion on the voyage out and in many excursions at the several ports was the botanist, David Douglas. Scouler's journal of the voyage reports the instruction he received from early workers on Vancouver's expedition, such as Archibald Menzies, familiarising himself with the botany of the regio ...

Hibbertopterus Scouleri
''Hibbertopterus'' is a genus of eurypterid, a group of extinct aquatic arthropods. Fossils of ''Hibbertopterus'' have been discovered in deposits ranging from the Devonian period in Belgium, Scotland and the United States to the Carboniferous period in Scotland, Ireland, the Czech Republic and South Africa. The type species, ''H. scouleri'', was first named as a species of the significantly different ''Eurypterus'' by Samuel Hibbert in 1836. The generic name ''Hibbertopterus'', coined more than a century later, combines his name and the Greek word πτερόν (''pteron'') meaning "wing". ''Hibbertopterus'' was the largest eurypterid within the stylonurine suborder, with the largest fossil specimens suggesting that ''H. scouleri'' could reach lengths around 180–200 centimetres (5.9–6.6 ft). Though this is significantly smaller than the largest eurypterid overall, ''Jaekelopterus'', which could reach lengths of around , ''Hibbertopterus'' is likely to have been the h ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
