Dinesidae is an extinct family of trilobite in the order Corynexochida. There are more than 20 genera and 70 described species in Dinesidae. [1]
These 25 genera belong to the family Dinesidae:
The Sokolnicheskaya line is a line of the Moscow Metro. It opened in 1935 and is the oldest in the system. There are currently 26 stations open on the line. As of 2019, the line is 44.5 kilometres (27.7 mi) long.
Horace Raymond Huntley was an English actor who appeared in dozens of British films from the 1930s to the 1970s. He also appeared in the ITV period drama Upstairs, Downstairs as the pragmatic family solicitor Sir Geoffrey Dillon.
Acontheus is a genus of trilobites belonging to the Family Corynexochidae, Order Corynexochida, and is geographically widespread having been recorded from middle Cambrian strata in Sweden, Newfoundland, Germany, Siberia, Antarctica, Queensland, China and Wales.
Habrocephalus is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period.
Ammagnostidae is a family of trilobites in the suborder Agnostina, small, eyeless, isopygous trilobites with a thorax consisting of 2 segments only. Four genera have been assigned to it:
Pelagiellidae is an extinct family of Paleozoic fossil marine molluscs.
Lingulella is a genus of phosphatic-shelled brachiopod. It is known from the Middle Cambrian Burgess Shale (Canada) to the Upper Ordovician Bromide Formation in North America. 346 specimens of Lingulella are known from the Greater Phyllopod bed, where they comprise 0.66% of the community.
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.
Salterella is an enigmatic Cambrian genus with a small, conical, calcareous shell that appears to be septate, but is rather filled with stratified laminar deposits. The shell contains grains of sediment, which are obtained selectively by a manner also observed in foramanifera. The genus was established by Elkanah Billings in 1861, and was named after the English palaeontologist John William Salter.
The ”Fallotaspidoidea” are a superfamily of trilobites, a group of extinct marine arthropods. It lived during the Lower Cambrian (Atdabanian) and species occurred on all paleocontinents except for the Gondwana heartland. A member of this group, Profallotaspis jakutensis, has long been the earliest known trilobite, but recently the redlichiid Lemdadella has been claimed as occurring even earlier.
Ptychagnostidae is a family of agnostid trilobites from the 5th Stage to the Paibian Age of the Cambrian. The family includes several important index fossils.
Mallagnostus Howell, 1935, is a trilobite genus belonging to the family Weymouthiidae Kobayashi T. (1943), Order Agnostida Salter (1864) according to Whittington et al. 1997. It lived during the late Lower Cambrian, with remains found in USA, Canada (Newfoundland), Spain, England, Russia, Mongolia, and the early Middle Cambrian as reported from China and Russia (Yakutia).
Tannudiscus Pokrovskaya (1959) is a genus of Eodiscinid trilobites belonging to the family Weymouthiidae Kobayashi T. (1943), Order Agnostida. It lived during the late Lower Cambrian, with remains found in Canada (Newfoundland), China (Gansu), The United Kingdom (England), and the Russian Federation.
Dorypygidae is a family of trilobite belonging to the order Corynexochida.
Elminae is a subfamily of riffle beetles in the family Elmidae. There are at least 120 genera and more than 1,300 described species in Elminae.
Edelsteinaspididae is an extinct family of trilobite in the order Corynexochida. There are about seven genera and at least two described species in Edelsteinaspididae.
Jakutidae is an extinct family of trilobite in the order Corynexochida. There are at least four genera and about seven described species in Jakutidae.
Corynexochidae Angelin, 1854, is an extinct family of trilobites within the order Corynexochida Kobayashi, 1935. According to Jell and Adrain (2002) there are at least 15 genera within the Family Corynexochidae:
Oryctocephalidae is an extinct family of trilobite in the order Corynexochida. There are more than 20 genera and 60 described species in Oryctocephalidae.
