vealed the man was a habitual tobacco user and that he chewed on his right side, based on the wear on his teeth, Runge explained.
• "That little piece right there, based on this one report, allows us to put a plug of tobacco in his right cheek," Runge said. "That little piece of evidence adds to the all-encompassing look of who this individual really was."
• In addition, David's $2,500 analysis of the deceased man's nine fillings, three of which were gold, revealed that Jackson had undergone multiple dental procedures by at least two different dentists, Runge said. He also noted that in the late 19th century, most individuals would have simply had a bothersome tooth extracted, indicating the pioneering prospector was likely a man of some means.
• "The gold leaf we saw on the fillings would have been done by someone with high expertise," he said. "Later procedures were done by someone else with less experience."
• Significantly, David also observed that Jackson did not hail from the East Coast, as researchers originally surmised. His analysis showed fluorosis in the man's teeth, a condition commonly known as "Colorado brown stain," caused by natural fluoride levels in the water consumed by an individual at an early age, Runge explained.
• "When you're an infant to when you develop your adult teeth, the water you consume contains oxygen isotopes," Runge said. "Those oxygen isotopes adhere to your teeth and are distinctive to the region where you were born and raised. Colorado brown stain is found in the region from Texas to Nebraska, but not in Dakota Territory."
• Planned isotopic analysis by forensic anthropologist Dr. Eric Bartelink of California State University-Chico will further refine where the man was born and raised, as well as what diet he had, Runge said.
• In coming months, Runge said the South Dakota School of Mines & Technology will conduct a spectral analysis of the gold found in the man's mouth to determine its origins.
• "The spectral analysis will tell us what the amalgam was made from, what the percentages of tin, silver and mercury were used, and where the gold originated," Runge said. "It will tell us if it's Black Hills gold or if the gold came from Africa, South America or Europe."
• With a DNA analysis currently being completed by Fort Worth, Texas-based DNA analyst Angie Ambers, researchers will begin to put a face on the man who died of unknown causes in Deadwood's earliest days. Ambers' work will help predict the man's hair, eye and skin color, revealing details that local historic preservation officials could not possibly ascertain, Runge said.
