A mysterious black sarcophagus discovered in Egypt two weeks ago has been opened by archaeologists, according to Egypt’s Ministry of Antiquities, revealing three skeletons and foul-smelling sludge. Reddish-brown sewage water inside the massive 2,000-year-old tomb weighing 27 tons, unearthed at a construction site, gave off a stench so pungent that initial prying efforts had to be abandoned. “We found the bones of three people, in what looks like a family burial,” said Mostafa Waziri, secretary-general of the Supreme Council of Antiquities, according to the BBC.
