Salteropterus
''Salteropterus'' is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Salteropterus'' have been discovered in deposits of Late Silurian age in Great Britain, Britain. Classified as part of the family Slimonidae, the genus contains one known valid species, ''S. abbreviatus'', which is known from fossils discovered in Herefordshire, England, and a dubious species, ''S. longilabium'', with fossils discovered in Leintwardine Beds, Leintwardine, also in Herefordshire. The generic name honours John William Salter, who originally described ''S. abbreviatus'' as a species of ''Eurypterus'' in 1859. ''Salteropterus'' is assumed to have been quite similar to its close relative ''Slimonia'', but the fragmentary nature of the fossil remains of ''Salteropterus'' make direct comparisons difficult. ''Salteropterus'' does however preserve a highly distinctive telson (the posteriormost division of the body) unlike any other in the Eurypterida. Beginning with an expanded ...

Slimonidae
Slimonidae (the name deriving from the type genus '' Slimonia'', which is named in honor of Welsh fossil collector and surgeon Robert Slimon) is a family of eurypterids, an extinct group of aquatic arthropods. Slimonids were members of the superfamily Pterygotioidea and the family most closely related to the derived pterygotid eurypterids, which are famous for their cheliceral claws and great size. Many characteristics of the Slimonidae, such as their flattened and expanded telsons (the posteriormost division of their bodies), support a close relationship between the two groups. Slimonids are defined as pterygotioid eurypterids with swimming legs similar to those of the type genus, ''Slimonia'', and the second to fifth pair of appendages being non-spiniferous. The family contains only two genera, the almost completely known ''Slimonia'' and '' Salteropterus'', which is known only from the telson and the metastoma (a large plate part of the abdomen). Both slimonid genera preserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herefordopterus
''Herefordopterus'' is a genus of eurypterid, an extinct group of aquatic arthropods. ''Herefordopterus'' is classified as part of the family Hughmilleriidae, a basal family in the highly derived Pterygotioidea superfamily of eurypterids. Fossils of the single and type species, ''H. banksii'', have been discovered in deposits of Silurian age in Herefordshire and Shropshire, England. The genus is named after Herefordshire, where most of the ''Herefordopterus'' fossils have been found. The specific epithet honors Richard Banks, who found several well-preserved specimens, including the first ''Herefordopterus'' fossils. ''Herefordopterus'' is classified in Hughmilleriidae, a pterygotioid family that is differentiated by their streamlined bodies, the enlargement of its medium-sized chelicerae and the presence of paired spines on the walking appendages. It was distinguished for combining characteristics of '' Hughmilleria'' with those of the derived pterygotioids, showing a more adva ...

Slimonia
''Slimonia'' is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Slimonia'' have been discovered in deposits of Silurian age in South America and Europe. Classified as part of the family Slimonidae alongside the related ''Salteropterus'', the genus contains three valid species, ''S. acuminata'' from Lesmahagow, Scotland, ''S. boliviana'' from Cochabamba, Bolivia and ''S. dubia'' from the Pentland Hills of Scotland and one dubious species, ''S. stylops'', from Herefordshire, England. The generic name is derived from and honors Robert Slimon, a fossil collector and surgeon from Lesmahagow. Out of the four described species of ''Slimonia'', three measured below or up to in length. Only ''S. acuminata'' was larger, with the largest specimens measuring in length. Though this is large for a predatory arthropod, ''Slimonia'' would be exceeded in length by later and more derived (more "advanced") members of the closely related pterygotid family of eurypterid ...

Pterygotus
''Pterygotus'' is a genus of giant predatory eurypterid, a group of extinct aquatic arthropods. Fossils of ''Pterygotus'' have been discovered in deposits ranging in age from Middle Silurian to Late Devonian, and have been referred to several different species. Fossils have been recovered from four continents; Australia, Europe, North America and South America, which indicates that ''Pterygotus'' might have had a nearly cosmopolitan (worldwide) distribution. The type species, ''P. anglicus'', was described by Swiss naturalist Louis Agassiz in 1839, who gave it the name ''Pterygotus'', meaning "winged one". Agassiz mistakenly believed the remains were of a giant fish; he would only realize the mistake five years later in 1844. ''Pterygotus'' was among the largest eurypterids. Isolated fossil remains of a large chelicera (frontal appendage) suggests that the largest known species, ''P. grandidentatus'', reached a body length of . Several other species, notably ''P. impacatus'' at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John William Salter
John William Salter (15 December 1820 – 2 December 1869) was an England, English natural history, naturalist, geologist, and palaeontologist. Salter was apprenticed in 1835 to James De Carle Sowerby, and was engaged in drawing and engraving the plates for Sowerby's ''Mineral Conchology'', the ''Supplement to Sowerby's English Botany'', and other natural history works. In 1842, he was employed for a short time by Adam Sedgwick in arranging the fossils in the Woodwardian Museum at Cambridge, and he accompanied the professor on several geological expeditions (1842–1845) into Wales. Salter was born in Pratt Place, Camden Town, the son of John Salter (1779–1837), a banking clerk, and his wife, Mary Ann. His birth was registered at Dr. William's Library near Cripplegate, London. In 1846, Salter married Sally, daughter of James De Carle Sowerby, and eventually fathered seven children with her. Also in 1846, Salter was appointed on the staff of the British Geological Survey, Geol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hughmilleria
''Hughmilleria'' is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Hughmilleria'' have been discovered in deposits of the Silurian age in China and the United States. Classified as part of the basal family Hughmilleriidae, the genus contains three species, ''H. shawangunk'' from the eastern United States, ''H. socialis'' from Pittsford, New York, and ''H. wangi'' from Hunan, China. The genus is named in honor of the Scottish geologist Hugh Miller. ''H. socialis'' is the type species of Hughmilleriidae, a eurypterid family classified in the superfamily Pterygotioidea that is differentiated by their streamlined bodies, the enlargement of their medium-sized chelicerae and the presence of paired spines on the walking appendages. With the biggest specimen measuring 20 centimetres (8 inches) in length, ''Hughmilleria'' is considered a eurypterid of small size. Description ''Hughmilleria'' is the most basal (primitive) known member of the Pterygotioidea. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
