Taylor said gnaw marks on the bones may indicate a rodent placed them inside the insulation. Dirt and plant material on the bones indicate they were outside at one time, Taylor said.

"Taylor said gnaw marks on the bones may indicate a rodent placed them inside the insulation."

I think it was just badly worded. I think the writer meant, placed the rodents with the bones.
