EXPERTS are trying to find out what caused the death of a seven-metre whale found washed up at a Purbeck beauty spot.

Lulworth Coastguard Rescue Officers discovered the creature at Worbarrow Bay. The incident was reported to the Natural History Museum and a vet will try to determine the cause of death.

The dead mammal is thought to be a pilot whale, a member of the dolphin family usually found in groups in cooler waters.
