Menticirrhus Ophicephalus
''Menticirrhus'' is a genus of marine ray-finned fish belonng to the family Sciaenidae, the drums or croakers. They are commonly known as kingcroakers or kingfish. These fish are found in the Western Atlantic and Eastern Pacific Oceans. Taxonomy ''Menticirrhus'' was first proposed as a genus in 1861 by the American biologist Theodore Gill with ''Perca alburnus'', a species described by Linnaeus in 1763 from Charleston, as its only species and designated as its type species. This genus has been placed in the subfamily Sciaeninae by some workers, but the 5th edition of ''Fishes of the World'' does not recognise subfamilies within the Sciaenidae which it places in the order Acanthuriformes. Etymology ''Menticirrhus'' is a combination of ''mentum'', meaning "chin", and ''cirrhus'', which means barbel, an allusion to the single thick barbel on the chin. Species ''Menticirrhus'' contains the following species: *''Menticirrhus americanus'' (Linnaeus, 1758) (Southern kingcroaker) *'' ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
