EAST CHEZZETCOOK, N.S. -- Human bones recently found near a beach east of Halifax are so old that the Medical Examiner Service considers them an archeological find, police say.

The bones were found Sunday by a group of beachcombers on Conrod Beach in Lower East Chezzetcook, about a 40-minute drive east of Halifax, RCMP Cpl. Greg Church said Thursday.

Medical examiner Marnie Wood said an anthropologist removed the bones, which were protruding from an eroded embankment next to the beach.

"They appear to be decades old," said Wood. "We're still investigating the origin of them and seeing if we can narrow the age a little bit, but for now it's being treated as historic remains not related to a current investigation."

She said a flat stone found near the remains could be a grave marker, but the stone was so eroded that it was unclear whether it ever had any markings on it.

"It's not a known cemetery or a known churchyard or burial ground," Wood said.

The anthropologist with the Medical Examiner Service is expected to prepare a formal analysis on the find, but Wood said it may be difficult to provide a more precise age for the remains.
