John William Salter was an English naturalist, geologist, and palaeontologist.
Paradoxides is a genus of large to very large trilobite found throughout the world during the Middle Cambrian period. One record-breaking specimen of Paradoxides davidis, described by John William Salter in 1863, is 37 cm (15 in). The cephalon was semicircular with free cheeks ending in long, narrow, recurved spines. Eyes were crescent shaped providing an almost 360° view, but only in the horizontal plane. Its elongate thorax was composed of 19-21 segments and adorned with longish, recurved pleural spines. Its pygidium was comparatively small. Paradoxides is a characteristic Middle-Cambrian trilobite of the 'Atlantic' (Avalonian) fauna. Avalonian rocks were deposited near a small continent called Avalonia in the Paleozoic Iapetus Ocean. Avalonian beds are now in a narrow strip along the East Coast of North America, and in Europe.
Runcinodiscus Rushton is a genus of Lower Cambrian Eodiscinid trilobite belonging to the family Weymouthiidae, Order Agnostida.
Strotactinus is an extinct genus of trilobite in the family Pliomeridae. There is one described species in Strotactinus, S. insularis.
Anacheirurus is a genus of trilobites. It was described by Reed in 1896, as a new genus for the species Cheirurus frederici, and was originally described by Salter in 1864.
Burmeisteria is a genus of trilobites in the order Phacopida that existed during the lower Devonian in what is now South Africa. It was described by Salter in 1865, and the type species is Burmeisteria herschelii, which was originally described under the genus Homalonotus by Murchison in 1839. It also contains the species B. accraensis, B. acuminata, and B. noticus. The type locality was the Bokkeveld Group.
Cybele is a genus of trilobites in the order Phacopida, that existed during the middle Ordovician in what is now Sweden. It was described by Loven in 1846, and the type species is Cybele bellatula, which was originally described dubiously under the genus Calymene by Dalman in 1827. The type locality was in Östergötland.
Daytonia is a trilobite in the order Phacopida, that existed during the lower Silurian in what is now the United States. It was described by D. J. Holloway in 1981, and the type species is Daytonia werthneri, which was originally described under the genus Dalmanites by August Foerste in 1885. It also contains the species, Daytonia mekon. The type locality for the genus was the Brassfield Formation, in Ohio.
Delops is a trilobite in the order Phacopida, that existed during the upper Silurian in what is now England. It was described by Rickards in 1964, and the type species is Delops obtusicaudatus, which was originally described under the genus Phacops by Salter in 1849. The type locality was the Middle Coldwell Beds.
Dianops is a genus of phacopid trilobite in the order Phacopida, that existed during the upper Devonian in what is now Germany. It was described by Richter and Richter in 1923, and the type species is Dianops limbatus, which was originally described under the genus Phacops by Richter in 1848. The type locality was in Saalfeld, Thuringia.
Frammia is a genus of trilobites in the order Phacopida that existed during the middle and upper Silurian in what is now the Arctic regions of Canada and Russia. It was described by Holtedahl in 1914, and the type species is Frammia dissimilis. That species was subsequently considered to be a synonym of Frammia arctica. The genus also contains the species, F. bachae Adrain & Edgecombe, 1997, F. hyperborea, and F. rossica. The type locality is the Douro Formation of Cornwallis Island in Nunavut, Canadian Arctic.
Frencrinuroides is a genus of trilobites in the order Phacopida, that existed during the upper Ordovician in what is now the United States. It was described by Lesperance and Desbiens in 1995, and the type species is Frencrinuroides capitonis, which was originally described under the genus Encrinuroides by Frederickson in 1964. The type locality was the Bromide Formation in Oklahoma.
Hintzeia is a genus of trilobites in the order Phacopida, that existed during the lower Ordovician in what is now the United States. It was described by Harrington in 1957, and the type species is Hintzeia aemula, which was originally described under the genus Protopliomerops by Hintze in 1953. Harrington also moved two other Protopliomerops species, P. celsaora and P. firmimarginis, under Hintzeia. The generic name is derived from that of the type species' author. The type locality was the Fillmore Formation in Utah.
Kanoshia is a genus of trilobites in the order Phacopida, that existed during the middle Ordovician in what is now Utah, USA. It was described by Harrington in 1957, and the type species is Kanoshia kanoshensis, which was originally described under the genus Pseudomera by Hintze in 1953. It also contains the species K. depressus and K. reticulata. The generic name is derived from the type species' epithet, which in turn is derived from the name of the type locality, the Kanosh Formation.
Aayemenaytcheia paragranulata is a Middle Devonian proetid trilobite.
Pagetia Walcott, 1916. is a small genus of trilobite, assigned to the Eodiscinid family Pagetiidae and which had global distribution during the Middle Cambrian. The genus contains 55 currently recognized species, each with limited spatial and temporal ranges.
Micragnostus is a genus of trilobite in the order Agnostida, which existed in what is now north Wales. It was described by Howell in 1935, and the type species is Micragnostus calvus, which was originally described as a species of Agnostus by Lake in 1906.
Proetus is a genus of proetid trilobite found in Silurian-aged marine strata of Europe.
Hedstroemia is a genus of trilobites in the order Proetida known from the Silurian period of Europe, Asia, and North America.
Plutonides is a genus of Middle Cambrian trilobite in the family Paradoxididae with species Plutonides sedgwickii and possibly Plutonides? illingi. Several other species and subspecies were at times placed in Plutonides but have subsequently been moved to other genera.
