A shark that lived 310 million years ago now is believed to have migrated from freshwater swamps of what is now the Mazon Creek fossil beds of Grundy and Will counties to spawn in distant tropical coastline waters.
The long-snouted "Bandringa" shark, possibly one of the closest relatives to modern sharks, behaved "like salmon in reverse," wrote Jim Erickson in the January issue "Michigan News," a University of Michigan magazine.
