Archaeologists have discovered a new pyramid under the sands of Saqqara, an ancient burial site that remains largely unexplored and has yielded a string of unearthed pyramids in recent years. The 4,300-year-old monument most likely belonged to the queen mother of the founder of Egypt's 6th Dynasty, several hundred years after the building of the famed Great Pyramids of Giza. The discovery is part of the sprawling necropolis and burial site of the rulers of ancient Memphis, the capital of Egypt's Old Kingdom. 11/12/08
