Paleontologist Dave Cicimurri digs up fossils 34.5 million years old, not in some wilderness spot, but almost in downtown Aiken. The ancient sharks, rays, barracudas and more tell him not only that the area was once the bottom of the ocean, but the very sediment they’re buried in contains information about the environment of past eras. This information, in turn, may point to where the environment is headed in the far-flung future.
