Apogon Rubrifuscus, A. Rubrifuscus
''Apogon'' is a large genus of fish in the family ''Apogonidae'', the cardinalfishes. They are among the most common fish on coral reefs. Over 200 species have been classified in genus ''Apogon'' as members of several subgenera. Some of these subgenera, such as ''Ostorhinchus'', have been elevated to genus status, leaving just over 50 species in the genus. Species The 50 recognized species in this genus are: * ''Apogon americanus, A. americanus'' Francis de Laporte de Castelnau, Castelnau, 1855 (Brazilian flamefish) * ''Apogon atradorsatus, A. atradorsatus'' Edmund Heller, Heller & Robert Evans Snodgrass, Snodgrass, 1903 (blacktip cardinalfish) * ''Apogon atricaudus, A. atricaudus'' David Starr Jordan, D. S. Jordan & Ernest Alexander McGregor, E. A. McGregor, 1898 (plain cardinalfish) * ''Apogon aurolineatus, A. aurolineatus'' (Louis Leon Arthur Mowbray, Mowbray, 1927) (bridle cardinalfish) * ''Apogon axillaris, A. axillaris'' Achille Valenciennes, Valenciennes, 1832 (axillary ...

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] |
