Eocarcinosoma
''Eocarcinosoma'' is a genus of eurypterid, an extinct group of aquatic arthropods. The type and only species of ''Eocarcinosoma'', ''E. batrachophthalmus'', is known from deposits of Late Ordovician age in the United States. The generic name is derived from the related genus ''Carcinosoma'', and the Greek () meaning 'dawn', referring to the earlier age of the genus compared to other carcinosomatid eurypterids. ''Eocarcinosoma'' is known only from a single specimen, a well-preserved small prosoma (head). In life it would have been a very small eurypterid, given that the head measures just 2.05 centimetres (0.8 in) in length. The main distinguishing features from other carcinosomatids were the eyes being placed on the margins of the carapace (head plate) and the head being more triangular in shape than in its later relatives. Although initially believed to be an adult given the relatively small size of the eyes, some researchers believe ''Eocarcinosoma'' to represent a juve ...

Carcinosomatidae
Carcinosomatidae (the name deriving from the type genus ''Carcinosoma'', meaning "crab body")Meaning osomaat ''www.dictionary.com''. Retrieved 7 September 2018. is a family of eurypterids, an extinct group of aquatic arthropods. They were members of the superfamily Carcinosomatoidea, also named after ''Carcinosoma''. Fossils of carcinosomatids have been found in North America, Europe and Asia, the family possibly having achieved a worldwide distribution, and range in age from the Late Ordovician to the Early Devonian. They were among the most marine eurypterids, known almost entirely from marine environments. Carcinosomatids varied considerably in size, from species only a few centimetres in length to some of the largest known arthropods. The largest carcinosomatid species, ''Carcinosoma punctatum'', reached lengths of at least and rivalled the largest eurypterid of all, ''Jaekelopterus'', in size. Morphologically, carcinosomatids were highly distinct from other eurypterids, k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paracarcinosoma
''Eusarcana'' (meaning "true flesh") is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Eusarcana'' have been discovered in deposits ranging in age from the Early Silurian to the Early Devonian. Classified as part of the family Carcinosomatidae, the genus contains three species, ''E. acrocephalus'', ''E. obesus'' and ''E. scorpionis'', from the Silurian-Devonian of Scotland, the Czech Republic and the United States respectively. ''Eusarcana'' is known for its odd proportions and features; the broad abdomen, thin and long tail, spined and forward-facing walking appendages and sharp and curved tail spike differentiate it from most other eurypterids, but are shared with other carcinosomatid eurypterids. The triangular carapace, oddly positioned forward-facing eyes differentiate the genus further from its closest relatives. At 80 centimetres (31.5 in) in length, ''E. scorpionis'' represents a moderately large species of eurypterid, and far exceeded ...

Rhinocarcinosoma
''Rhinocarcinosoma'' is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Rhinocarcinosoma'' have been discovered in deposits ranging of Late Silurian age in the United States, Canada and Vietnam. The genus contains three species, the American ''R. cicerops'' and ''R. vaningeni'' and the Vietnamese ''R. dosonensis''. The generic name is derived from the related genus ''Carcinosoma'', and the Greek ῥινός (rhinós, "nose"), referring to the unusual shovel-shaped protrusion on the front of the carapace (head plate) of ''Rhinocarcinosoma'', its most distinctive feature. Other than the protrusion, ''Rhinocarcinosoma'' was anatomically very similar to its close relative, ''Eusarcana'', though it lacked the scorpion-like telson (the posteriormost division of the body) of that genus. Further distinguishing features include more slender appendages and slightly different ornamentation of scales. In terms of size, ''Rhinocarcinosoma'' was a medium-sized carc ...

Carcinosoma
''Carcinosoma'' (meaning "crab body") is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of ''Carcinosoma'' are restricted to deposits of late Silurian (Late Llandovery to Early Pridoli) age. Classified as part of the family Carcinosomatidae, which the genus lends its name to, ''Carcinosoma'' contains seven species from North America and Great Britain. Carcinosomatid eurypterids had unusual proportions and features compared to other eurypterids, with a broad abdomen, thin and long tail and spined and forward-facing walking appendages. They were not as streamlined as other groups but had considerably more robust and well developed walking appendages. In ''Carcinosoma'', these spined walking appendages are thought to have been used to create a trap to capture prey in. The telson (the posteriormost division of the body) of ''Carcinosoma'' appears to have possessed distinct segmentation, ''Carcinosoma'' is the only known eurypterid to possess this feature. ...

Carcinosomatoidea
Carcinosomatoidea is an extinct superfamily of eurypterids, an extinct group of chelicerate arthropods commonly known as "sea scorpions". It is one of the superfamilies classified as part of the suborder Eurypterina. Some carcinosomatoid genera have been suggested to have been fully marine as opposed to living in near-shore brackish or hypersaline environments. The majority of carcinosomatoid taxa are known from the paleocontinents of Laurentia, Baltica and Avalonia. Isolated and fragmentary fossils from the Late Silurian of Vietnam and the Czech Republic show that the terranes of Annamia and Perunica were within the geographical range of the carcinosomatoids. Only a few basal carcinosomatoids (e.g. ''Carcinosoma'' and '' Paracarcinosoma'') have been found in deeper waters whilst the more derived forms, such as '' Mixopterus'' and ''Lanarkopterus'' have not. Basal carcinosomatoids (Carcinosomatidae) are likely responsible for the fossil remains in Vietnam and the Czech Republic ...

Holmipterus
''Holmipterus'' is a problematic genus of eurypterid, an extinct group of aquatic arthropods. The type and only species of ''Holmipterus'', ''H. suecicus'', is known from deposits of Middle Silurian age in the Sweden. The generic name honours , a renowned Swedish palaeontologist specialising in arthropods and crustaceans, and the species name ''suecicus'' is Latin for 'Swedish'. Although ''Holmipterus'' was a large eurypterid and is known from multiple, albeit partial and fragmentary, specimens, it has proven difficult to determine where it fits in the eurypterid family tree. This is due to the fossil material referred to ''Holmipterus'' combining traits seen in different eurypterid groups, such as the Carcinosomatidae and Megalograptidae, and has some distinctive features, such as a telson (the posteriormost division of the body) with two articulating 'cercal blades', forming an organ capable of grasping. Though often classified either as a carcinosomatid or megalograptid, ''Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Ordovician ( ) is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Geological Congress. Life continued to flourish during the Ordovician as it did in the earlier Cambrian Peri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
