Edward J. Williams was laying possum traps off Foundation Drive near the Garden City city limits around 6 p.m. when he stumbled onto what he called a shallow grave.
The decomposed body, which was mostly bones, was lying in the weeds, Savannah-Chatham Metropolitan Police spokesman Bucky Burnsed said.
Police gathered the remains and turned them over to the GBI to identify the body, Burnsed said. Police are unsure of the individual's gender, race or age.
"The body has been there awhile," Burnsed added.
