Cymatium (gastropod)
''Cymatium'' is a genus of small to large predatory sea snails, marine gastropod mollusk Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is e ...s in the family (biology), family Cymatiidae. This genus has numerous species, perhaps as many as 100, some of which have a cosmopolitan distribution, worldwide distribution. The genus has been divided into at least 10 subgenera. Some authors have elevated those subgenera, giving them the full status of genera, but this is by no means universally accepted. Fossil records This genus is known in the fossil records from the Eocene to the Quaternary (age range: from 55.8 to 0.012 million years ago). Description These sea snails have separate sexes. They lay egg capsules. After hatching, the larvae have a planktonic stage that can (in some species) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Cymatium Gutturnium
Cymatium, the uppermost molding at the top of the cornice in the classical order, is made of the s-shaped cyma molding (either ''cyma recta'' or ''cyma reversa''), combining a concave cavetto with a convex ovolo. It is characteristic of Ionic columns and can appear as part of the entablature, the epistyle or architrave, which is the lintel or beam that rests on the capitals of columns, and the capital itself. Often the cymatium is decorated with a palmette or egg-and-dart ornament on the surface of the molding. The heights of the parts of the capital are to be so regulated that three of the nine parts and a half, into which it was divided, lie below the level of the astragal on the top of the shaft. The remaining parts are for the cymatium, abacus, and channel. The projection of the cymatium beyond the abacus is not to be greater than the size of the diameter of the eye f the voluteIn the case of a concave-convex profile, a distinction is made between cyma recta and cyma reversa, ...
