Police were called to a Yorkshire canal towpath after a member of the public saw what they thought were human remains.
West Yorkshire Police were called to a stretch of the Aire and Calder Navigation near Lock Lane in Castleford after the alarm was raised on Sunday afternoon.
A member of the public is believed to have been very concerned that the remains may have been those of a small child.
A stretch of the path, near to Bulhome Lock, was cordoned off and a police evidence tent was put up while crime scene investigation officers examined the remains.
But their enquiries determined that what was found actually belonged to an animal.
A police spokeswoman said the incident was dealt with by 7.30pm.
