Some people believe that Ogopogo can be explained as a kind of water dinosaur left over from the Ice Age. In fact, there have been several cases over the last century where creatures with prehistoric origins have been found. In 1938, a lungfish, thought to be extinct, was found off the coast of South Africa. In the 1950s, fishermen in the Indian Ocean pulled up a large fish called a coelacanth. It was supposed to have been extinct for millions of years. In 1976, a long creature never before seen by man was caught by the American navy near Hawaii. It was later named a megamouth shark because it had 2,000 teeth. In 1977, a fishing boat off New Zealand hauled up a 30-foot long creature which resembled an extinct sea reptile. It looked like a plesiosaur. The plesiosaurs were a family of marine reptiles that swam the oceans when dinosaurs roamed the land. They were long-necked beasts with small heads and long tails. They grew to be 15 - 40 feet long. Arlene Gaal of Kelowna believes that Ogopogo is some form of plesiosaur. The Okanagan Valley was originally gouged out by glaciers. At one time, the lake may have even been open to the ocean. Maybe creatures were trapped in lakes when the glaciers from the Ice Age melted, and they have somehow managed to survive to the present day.
