It's a mystery in Mishawaka. Artifacts, more than 100 years old were unearthed by landscapers Tuesday on the edge of the city near University Drive and Fir Road.
An Indiana Conservation Officer on scene quickly identified the objects as bones and cement stones.
Archaeologists say the bones found aren't human and the monuments found date back to before 1870 making all these finds, artifacts.
"People are finding things in their yards all the time," said South Bend Archaeologist and IUSB Professor Jay Vanderveen. “The people doing some landscaping found something that looked like a headstone and some bones.”
Instinct and observation told these researchers the bones didn't look like human remains.
“The bones have been cut and there's knife marks on it, when we see that like a bone saw, that’s something that a butcher would use," said Jonathan Boyd, an Indiana Conservation Officer with the Department of Natural Resources.
