Fish that died out at the time of the dinosaurs are back

The dead coming back to life sounds scary.But for scientists, it can be a wonderful opportunity.Of course, we're not talking about zombies.Rather, this particular opportunity came in the unlikely form of large, slow-moving fish called the coelacanth.This oddity dates back 360 million years,and was believed to have died out during the same mass extinction event that wiped out the dinosaurs 65 million years ago.
