Chariaster
''Chariaster'' is an extinct genus of prehistoric starfish in the family Ophidiasteridae The Ophidiasteridae (Greek ''ophidia'', Οφιδια, "of snakes", diminutive form) are a family of sea stars with about 30 genera.

List Of Prehistoric Echinoderm Genera
This list of prehistoric echinoderms is an attempt to create a comprehensive listing of all genera that have ever been included in the Echinoderms that have been preserved as fossils. This list excludes purely vernacular terms. It includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered echinoderms. The list includes thousands of genera. * Extinct genera are marked with a dagger (†). *Extant genera are bolded. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be pu ...

Ophidiasteridae
The Ophidiasteridae (Greek ''ophidia'', Οφιδια, "of snakes", diminutive form) are a family of sea stars with about 30 genera. Occurring both in the Indo-Pacific and Atlantic Oceans, ophidiasterids are greatest in diversity in the Indo-Pacific. Many of the genera in this family exhibit brilliant colors and patterns, which sometimes can be attributed to aposematism and crypsis to protect themselves from predators. Some ophidiasterids possess remarkable powers of regeneration, enabling them to either reproduce asexually or to survive serious damage made by predators or forces of nature (an example for this is the genus ''Linckia''). Some species belonging to ''Linckia'', ''Ophidiaster'' See last paragraph in review above Analysis and ''Phataria'' shed single arms that regenerate the disc and the remaining rays to form a complete individual. Some of these also reproduce asexually by parthenogenesis. The name of the family is taken from the genus ''Ophidiaster'', whose limbs ar ...

List Of Prehistoric Starfish Genera
This list of prehistoric starfish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be in the class Asteroidea, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published ('' nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered starfish. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms. Senior synonyms are gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perceval De Loriol
Charles Louis Perceval de Loriol (24 July 1828, Geneva – 23 December 1908, Cologny) was a Swiss paleontologist and stratigraphist. He studied natural sciences and paleontology in Geneva as a pupil of François-Jules Pictet. For a period of time, he worked as an estate manager in Geneva and Lorraine, then for nearly forty years was associated with the Natural History Museum of Geneva. He was one of the founders of the ''Schweizerische Paläontologische Gesellschaft'' and was an editor of the ''Mémoires de la Société suisse paléontologique''. In 1902 he received an honorary doctorate from the University of GenevaLoriol, Perceval de Historischen Lexikon der Schweiz He is remembered for his investigations of fossil |
Prehistoric Starfish Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
