A fearsome fish whose roots date back 120 million years is getting a second chance in Illinois waterways. The alligator gar had been found as far north as Beardstown within the past century. But the last known catch was in 1966 in Cairo and Illinois officials declared in 1994 that it no longer swam state rivers. The (Springfield) State Journal Register reports Sunday that's changed in recent years with efforts by the U.S. Fish and Wildlife Service to reintroduce the predator that has inhabited the Mississippi River for three million years.
