The museum describes it as an "exceptional discovery" and says the use of both young and older crocodiles could reflect the ancient Egyptians' belief in life after death. The scan was originally planned as part of preparations for a new exhibit which allows visitors to carry out an "interactive virtual autopsy" on the both the crocodile mummy and that of an Egyptian priest. It will give people a chance to examine each layer and also get a close-up 3D view of the amulets inside the wrappings, the museum says.
