Abakania
''Abakania'' is an extinct genus of corynexochida, corynexochid trilobite in the family Corynexochidae. It lived during the Botomian, Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period. Distribution * ''A. superba'' occurs in the Lower Cambrian of the Russian Federation (Botomian, Sanashtykgol Spring, Sanashtykgol Formation, Altay-Sayan Region, 49.4° N, 136.4° E). * ''A. crassa'' is present in the Lower Cambrian of the Russian Federation (Botomian, Kiya River section, ''Poliellaspis''-zone, Usa Formation, Kemorovo, Kuznetsk Alatau, 56.0° N, 88.0° E).

Acontheus
''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. ''Acontheus'' appears confined to the Drumian and Guzhangian Stages, uppermost two of three Stages subdividing the middle Cambrian Miaolingian Series and, if species assignments are correct, the genus ranges in terms of the Scandinavian sequence from at least the ''Hypagnostus parvifrons'' Biozone in Wales to the ''Lejopyge laevigata'' Biozone at various locations elsewhere. Taxonomy ''Acontheus'' has been placed in the subfamily Acontheinae (See Cotton, 2001, p. 194). Cotton (''op. cit.'') also erected Tribe HARTSHILLINI within the Acontheinae to accommodate the highly derived genera ''Hartshillia'' Illing, 1916 and ''Hartshillina'' Lake, 1940. Öpik (1982, p. 77) placed Acontheinae in the Doli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shivelicus
''Shivelicus'' 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 The Cambrian Period ( ; sometimes symbolized Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (m ....

Corynexochida
Corynexochida is an order of trilobite that lived from the Lower Cambrian to the Late Devonian The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, w .... Like many of the other trilobite orders, Corynexochida contains many species with widespread characteristics. The middle region of the cephalon (the glabella) is typically elongate, with the sides often spreading forward (pestle-shaped). Some species have glabellae that are ''effaced'', meaning they are smooth and show little detail. The glabellar furrows (when not effaced) typically have a splayed arrangement. In most species, the hind pair on either side of the cephalon become spines that point sharply backwards, and the spinose tips of the anterior pairs of thoracic segments tend to become more and more forward directed toward the p ...
