Astropectinidae
The Astropectinidae are a family of sea stars in the order Paxillosida. Usually, these starfish live on the seabed and immerse themselves in soft sediment such as sand and mud. They are not to be confused with species in the genus ''Archaster'', which share similar shape and life habits, but belong to the family Archasteridae (order Valvatida). Genera There are 27 genera in the family: * '' Astromesites'' Fisher, 1913 * '' Astropecten'' Gray, 1840 * ''Astropectinides'' Verrill, 1914 * '' Bathybiaster'' Danielssen & Koren, 1883 * '' Blakiaster'' Perrier, 1881 * ''Bollonaster'' McKnight, 1977 * '' Bunodaster'' Verrill, 1909 * ''Craspidaster'' Sladen, 1889 * ''Ctenophoraster'' Fisher, 1906 * ''Ctenopleura'' Fisher, 1913 * ''Dipsacaster'' Alcock, 1893 * ''Dytaster'' Sladen, 1889 * '' Koremaster'' Fisher, 1913 * '' Leptychaster'' E.A. Smith, 1876 * '' Lonchotaster'' Sladen, 1889 * '' Macroptychaster'' H.E.S. Clark, 1963 * '' Mimastrella'' Fisher, 1916 * '' Patagiaster'' Fisher, 19 ...

Prehistoric Echinoderms Of Europe
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] |
Cretaceous Echinoderms
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by th ...

Jurassic Echinoderms
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, t ...
