Coelacanth

The coelacanth is a very old creature. It came before the dinosaurs in a period called the Devonian. It went from that age all the way to this age. A long time ago people used to think they all died out. But some people found a coelacanth off the coast of South Africa, which proved that they still roamed the waters off of Africa.
