BOCA RATON (AP) – Investigators say remains that washed ashore at a South Florida beach aren’t human bones.

The Palm Beach County Medical Examiner’s Office believes the bones that were found at South Inlet Park in Boca Raton on Monday afternoon belong to an unknown type of animal.

Deputy Eric Davis, a spokesman for the Palm Beach County Sheriff’s Office, says authorities were called to the scene after someone reported the remains. Officials aren’t sure where the remains came from.
