Killgrove has already done some preliminary work, examining the content ofthe bones for isotopes and other chemicals that can explain the day to day lifeof Romans.

However, they stress that the results are not directly transferable to humans yet, as the levels ofchemicals used on the rats were many times more concentrated than anything a person would experience in normal life.
