In South Africa, in 1938, a group of fishermen returning home noticed something much larger than normal in their daily catch. It measured five feet long, weighed 200 pounds and was covered with strange, silver markings. After careful examination, the creature was finally identified as a Coelacanth, a large salt water fish that was thought to be extinct for the past 65 million years. This living fossil was supposed to have died out with the mass extinction of the dinosaurs, which makes this a fascinating discovery. (Getty Images)
