In Ancient Egypt animal mummies were routinely placed in some type of container once the animal had been wrapped in linen. At times elaborate coffins were crafted to hold the animal mummies. Just as human coffins were anthropoid, some animal coffins took the form of the animal contained. The ibis mummy held by this coffin was placed within through the detachable lid on the back. The gilding of the body and the exquisite detailing of the head, legs, and feet make this example one of the finest of its kind. (Source)
