Coelacanths are an order of lobe-finned fish related to lungfish and tetrapods.
They first appeared in the Devonian period, and for many years, were believed to have gone extinct at the
Cretaceous period.
However, a living specimen was found in a fishing net brought ashore in
South Africa in
1938
(and since then other specimens have brought ashore at a number of locations around the Indian Ocean).
Coelacanth were very successful and widespread from the Devonian until the
Cretaceous.
Scientists now think that what happened is that they suffered a near total extinction at the end of the
Cretaceous. that wiped out
all shallow-water species, and left only hard-to-find deep-water species (fossils are rarely lifted from, or recovered from, deep-water locations).
Because of their apparent disappearance from the fossil
record for millions of years, and their later discovery alive, Coelacanths are known as a "Lazarus taxon".
One interesting aside about Coelacanths is that they are offered described in the popular media as having been
unchanged for millions of years, but this is not the case. Neither of the two currently known living species, nor any other members of their genus, have been found in the
fossil
record.

The coelacanth (see-lo-canth) is no ordinary fish. Five feet long, with luminescent eyes and limb like fins, this bizarre creature, presumed to be extinct, was discovered in 1938 by an amateur icthyologist who recognized it from fossils dating back 400 million years. The discovery was immediately dubbed the "greatest scientific find of the century," but the excitement that ensued was even more incredible. This is the entrancing story of that most rare and precious fish -- our own great-uncle forty million times removed. |

Product Description:
"An engrossing tale of obsession, adventure and scientific reasoning." —Betty Ann Kevles, Los Angeles Times In the winter of 1938, a fishing boat by chance dragged from the Indian Ocean a fish thought extinct for 70 million years. It was a coelacanth, which thrived concurrently with dinosaurs and pterodactyls—an animal of major importance to those who study the history of vertebrate life.
Living Fossil describes the life and habitat of the coelcanth and what scientists have learned about it during fifty years of research. It is an exciting and very human story, filled with ambitious and brilliant people, that reveals much about the practice of modern science. |
