Back from the dead: Living fossil identified Rodent had been thought to have died out 11 million years ago ...The discovery is an example of what scientists call the "Lazarus effect," a situation when an animal known only through the fossil record is found living. Perhaps the best known example of the Lazarus effect is the coelacanth, a lobe-finned fish discovered off the coast of South Africa that scientists thought died out at least 65 million years ago. Most examples of the Lazarus effect in mammals, though, only go back 10,000 years or so. "It is an amazing discovery and it's the coelacanth of rodents," said study coauthor Mary Dawson of the Carnegie Museum of Natural History. "It's the first time in the study of mammals that scientists have found a living fossil of a group that's thought to be extinct for roughly 11 million years. That's quite a gap. Previous mammals had a gap of only a few thousand to just over a million years."... msnbc.msn.com
