The remains discovered on Gorleston beach most likely belonged to a porpoise, a marine wildlife expert has said.
Kevin Murphy, a volunteer marine mammal medic and founder of Norfolk Wildlife Rescue, has said the remains are almost certainly that of the aquatic creature.
Mr Murphy said: 'Looking at the pictures and the location it was found in, I would say it is more than likely to be a porpoise. Almost definitely if it is around there'
The remains were discovered on Thursday, September 7, by Scott Fryer, who came across them on the beach around 200m from the car park.
Mr Fryer said he believed it was a dog, however Mr Murphy is confident it is not.
He added: 'I am very doubtful that it is a dog and really hope it is not.
'In my experience, more often than not remains do end up washed up on beaches or blown by the wind for somebody to discover.'
