Atrypa
''Atrypa'' is a genus of brachiopod with shells round to short egg-shaped, covered with many fine radial ridges (or costae), that split further out and growth lines perpendicular to the costae and 2-3 times wider spaced. The pedunculate valve is a little convex, but tends to level out or even become slightly concave toward the anterior margin (that is: opposite hinge and pedicle). The brachial valve is highly convex. There is no interarea (that is a flat area bordering the hinge line approximately perpendicular with the rest of the valve) in either valve. ''Atrypa'' was a cosmopolitan and occurred from the late Lower Silurian (Telychian) to the early Upper Devonian (Frasnian). Other sources expand the range from the Late Ordovician to Carboniferous, approximately from 449 to 336 Ma.''Atrypa'' at [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cavusgnathus
''Cavusgnathus'' is an extinct genus of conodonts. Glen K. Merrill A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower ... stated in 1963 that "conodont workers have considered '' Idiognathoides'' to be a junior synonym of '' Polygnathodella'' but it now proves to be a junior synonym of ''Cavusgnathus''. ''Polygnathodella'' and ''Cavusgnathus'' are shown to form a transitional series."Polygnathodella Harlton, 1933, or Idiognathoides Harris and Hollingsworth, 1933? Glen K.

Carinamala
''Carinamala'' is an extinct genus from the trilobite class of fossil marine arthropods which lived from 501 to 490 million years ago during the Dresbachian faunal stage of the late Cambrian Period The Cambrian Period ( ; sometimes symbolized C with bar, Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon.

Caninia (genus)
''Caninia'' is an extinct genus of rugose coral. Its fossils occur worldwide from the Devonian to the Permian periods. Paleoecology It was marine in nature and known to live in lagoon-type ecosystem An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the syste ...s. Because of the shallow water in which it lived, Caninia was often affected by processes above the water level, such as storms.

Campbelloceras
''Campbelloceras'' is a tarphyceratid nautiloid known from the Lower Ordovician, Upper Canadian Epoch of North America, where it is widespread. ''Campbelloceras'' was named by Ulrich and Foerste in 1936. The shell of ''Campbelloceras'' has a circular whorl section, only slightly impressed, and a siphuncle that is close to the venter in all growth stages. ''Campbelloceras'' differs from ''Tarphyceras'' in that the rate of expansion is greater, the siphuncle is proportionally largers, and an impression is shallower. ''Campbelloceras'' may have given rise to the barrandeocerid '' Plectoceras'' (Plectoceratidae) through simplification of the connecting rings, and to ''Tarphyceras'' through tighter coiling, development of a deeper impression, and reduction in the size of the siphuncle. ''Campbelloceras'' may be conceivably derived from '' Estonioceras'' (Estonioceratidae). The cross section of ''Campbelloceras'' and that of the outer whorl of ''Estonioceras'' are similar, except f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calamites Undulatus
''Calamites'' is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus '' Equisetum'') are closely related. Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of 30-50 meters (100-160 feet). They were components of the understories of coal swamps of the Carboniferous Period (around ). Taxonomy A number of organ taxa have been identified as part of a united organism, which has inherited the name ''Calamites'' in popular culture. ''Calamites'' correctly refers only to casts of the stem of Carboniferous/Permian sphenophytes, and as such is a form genus of little taxonomic value. There are two forms of casts, which can give mistaken impressions of the organisms. The most common is an internal cast of the hollow (or pith-filled) void in the centre of the trunk. This can cause some confusion: firstly, it must be remembered that a fossil was probably surrounded with 4-5 times its width in (unpres ...
