picture info	Genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

	Megistaspis ''Megistaspis'' is a genus of trilobites in the order Asaphida and family '' Asaphidae''. They lived in the Ordovician period (478-449 million years ago), from the Upper Tremadocian age until the Lower Llanvim age. These arthropods were a low-level epifauna, fast-moving and detritivore. Distribution Ordovician of Australia, China, Colombia (Serranía de la Macarena, Meta), the Czech Republic, Iran, Norway, United States (Nevada); Arenig of Argentina, Bolivia, China, France, Norway, Sweden, United States (Montana); Dawan of China; Arenigian of Argentina.''Megistaspis'' at Fossilworks Fossilworks is a portal which provides query, download, and analysis tools to f ...

	Conocoryphe ''Conocoryphe'' is a genus of primarily eyeless trilobites belonging to the family Conocoryphidae. They lived during the Middle Cambrian period, about 505 million years ago. These arthropods lived on the sea bottom ( epifaunal) and lived off dead particulate organic matter (a lifestyle called detritivorous). Distribution Cambrian of the Czech Republic, France, Spain, Turkey, United States (Wisconsin). Taxonomy ''Conocephalites'' Barrande, 1852 was introduced as a replacement for ''Conocephalus'' Zenker, 1833, which was unavailable since Thunberg (1815 ) had previously used the name for a genus of conehead bushcricket. Barrande, however, was unaware that ''Conocoryphe'' had already been proposed by Hawle and Corda in 1847.

	Orphanaspis ''Orphanaspis'' is a poorly known genus of odontopleurid trilobite in the family Odontopleuridae. The genus is originally based on poorly preserved material from the Wenlock-aged Motol Formation in Bohemia, Czech Republic, described by Joachim Barrande, in 1852, as "''Trilobites orphana.''" In 1945, Prantl and Pribyl reclassify ''T. orphana'' as ''Orphanaspis orphana.'' Some experts suspect that ''O. orphana'' may actually be a species of ''Dicranurus ''Dicranurus'' (Greek, 'dikranon', a pitchfork, and 'oura', tail) is a genus of Lower to Middle Devonian odontopleurid trilobites that lived in a shallow sea that lay between Euramerica and Gondwana, corresponding to modern-day Oklahoma and N ...''.

	Hydrocephalus (trilobite) ''Hydrocephalus'' ("water head") is an extinct genus of redlichiid trilobite that was very common during the Middle Cambrian of Eurasia and North America, which lasted from 508 to 497 million years ago. This trilobite is up to 20 cm long and more widely built than others of the time. In comparison to other members of its family, its glabella appears swollen.

picture info	Trilobite Trilobites (; meaning "three lobes") are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period () and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, they left an extensive fossil record. The stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Acernaspis ''Acernaspis'' is an extinct genus of trilobite that is known from the Silurian. It contains two species, ''A. elliptifrons'', and ''A. salmoensis''. It is sometimes found preserved in burrows of various forms, sometimes in association with multiple moults, suggesting that it used tunnels as refuges whilst in its vulnerable moulting stage.
