Construction has come to a halt at a work site in Barrington, Rhode Island, after possible human bones were found by an excavator operator there.
NBC10 Boston affiliate WJAR reports that the surprising find was made at Elm Lane on Thursday. The bones are now with the medical examiner's office.
Authorities don't know how long the bones were there, but the house that used to stand there was built in 1949, WJAR reports.
The Rhode Island Department of Health has since confirmed the bones that were found are indigenous human skeletal remains, according to WJAR. The site where the bones were buried is a historical tribal burial site, officials say.
An archeologist is working with federally recognized tribes to figure out where the bones will be released.
