Egyptian antiquities officials on Saturday announced the discovery of at least 100 ancient coffins, some with mummies inside, and around 40 gilded statues in a vast Pharaonic necropolis south of Cairo. Colorful, sealed sarcophagi and statues that were buried more than 2,500 years ago were displayed in a makeshift exhibit at the feet of the famed Step Pyramid of Djoser at Saqqara. Archaeologists opened a coffin with a well-preserved mummy wrapped in cloth inside.
