I clar up some misconceptions about the coelecanth. The species we have found today in our waters are not the ones that went extinct. The coelecanth is a family of fishes we thought to be extinct, until we ffound these 2 species completely new to science.
Well...yeah sorta...
The Coelacanth specimen caught in 1938 is still considered to be the zoological find of the century. This 'living fossil' comes from a lineage of fishes that was thought to have been extinct since the time of the dinosaurs.
Coelacanths are known from the fossil record dating back over 360 million years, with a peak in abundance about 240 million years ago. Before 1938 they were believed to have become extinct approximately 80 million years ago, when they disappeared from the fossil record.
It is the only living member of a very old group of fishes, the actinistians (Coelanacanthimorpha). About 120 species of coelacanths are known from fossils. They were predominantly small marine fish (though some lived in freshwater) which were thought to have died out at the end of the Mesozoic era more than 60 million years ago. They flourished in the Triassic; a fossil of a coelacanth (Whiteia) was discovered in the Orange Free State which dates to that time .The Coelacanthimorpha and lungfishes are separate side-branches of the primitive fish group that gave rise to the amphibians, reptiles, birds and mammals. Although Latimeria is not a “missing link” in the story of evolution, it is the sole survivor of a line of development that otherwise became extinct.
