The jawbone of a "prehistoric Native American" was discovered on the Iowa River in Marshall County last month.
During a biological study near the Iowa River, Marshall County Conservation Staff members and Marshall County Sheriff's Deputies discovered a lower human jawbone.
Three other bones that were allegedly human were discovered nearby. To ascertain their source, an inquiry was begun.
The Office of the State Archaeologist at the University of Iowa received the remains from the State Medical Examiner for additional analysis.
The mandible was presumably from a middle-aged or older male "prehistoric Native American," according to the archaeologist's office.
