''Champsodon'' is the sole genus in the family Champsodontidae. These fishes, the crocodile toothfishes, are native to the Indo-Pacific region. Although ''Champsodon'' is the only extant genus of this family, a close relative is known in the extinct ''Eochampsodon'' Bannikov, 2004 from the Eocene, Middle Eocene (Bartonian) of the North Caucasus, Russia. Species The currently recognized species in this genus are: * ''Champsodon atridorsalis'' Akira Ochiai, Ochiai & Izumi Nakamura, I. Nakamura, 1964 * ''Champsodon capensis'' Charles Tate Regan, Regan, 1908 (gaper) * ''Champsodon fimbriatus'' Charles Henry Gilbert, C. H.

Middle Eocene
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). 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.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 ...
