Hinnites
''Hinnites'' is a genus of rock scallops, marine bivalve mollusks in the family Pectinidae, the scallops. These mollusks have been recorded as fossils from the Triassic to the Quaternary (from 235.0 to 0.126 Ma). Fossils have been found in the sediments of Algeria, Angola, Tanzania, Ethiopia, South Africa, Oman, Saudi Arabia, United States, Australia and of various European countries. Description This genus include scallops with thick shells resembling that of an oyster. ''Hinnites'' is unusual in that, like the extant taxon ''Crassadoma gigantea'', it was free-swimming as a juvenile, but subsequently cemented itself to a hard substrate. Species Species within the genus ''Hinnites'' include: * ''Hinnites corallinus'' G. B. Sowerby I, 1827 * ''Hinnites crispus'' † (Brocchi, 1814) * ''Hinnites denticostatus'' † Klipstein 1843 * ''Hinnites distortus'' (da Costa, 1778) * ''Hinnites ercolanianus'' † Cocconi 1873 * ''Hinnites granulosus'' † Klipstein 1843 * ''Hinnites obliq ...

Scallop
Scallop () is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crassadoma Gigantea
''Crassadoma'' is a genus of rock scallops, marine bivalve molluscs in the family Pectinidae. It is monotypic, the only species being ''Crassadoma gigantea'', the rock scallop, giant rock scallop or purple-hinge rock scallop. Although the small juveniles are free-swimming, they soon become sessile, and are cemented to the substrate. These scallops occur in the eastern Pacific Ocean. Description Adults of ''Crassadoma gigantea'' have one valve (the right valve) fixed to a base, often a vertical rock face. This valve often becomes deformed to fit the contours of the rock. The left valve is roughly circular but irregular in outline, thick and heavy, with deep radial ribs. Every third or fourth rib is clad with blunt spines that overhang each other. These often get abraded and worn smooth as the scallop ages. There are flaps of shell known as auricles on either side of the straight hinge. The general colour is brown with the inside of the shell being glossy white with a purple patch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...
