The artifact was identified as a bannerstone that could be more than 4,000 years old. Archaeologists debate the purposes of bannerstones, but they are commonly found in Indiana, Michigan and Ohio. Some suggest they were used as weights for throwing spears; others think they were used for drilling or starting fires.
An engineering administrator for the city found the stone sitting on top of dirt at the edge of the construction site. The city met with an Indiana Department of Natural Resources archaeologist Saturday. After an investigation, it was concluded that the discovery was an “isolated find.”
State law requires work be stopped within 100 feet of an archaeological find until the DNR is contacted and an investigation takes place. Construction continued on the center of the roundabout, one of 32 roundabouts being built through a $257 million bond package. The news release said the city also contacted Conner Prairie for assistance.
