Egyptian authorities Saturday unveiled a well-preserved mummy of a woman inside a previously unopened coffin in southern Egypt dating back more than 3,000 years.

The sarcophagus, an ancient coffin, was one of two found earlier this month by a French-led mission in the northern area of El-Asasef, a necropolis on the west bank of the Nile. The first one had been opened earlier and examined by Egyptian antiquities officials.

"One sarcophagus was "rishi"-style, which dates back to the 17th Dynasty, while the other sarcophagus was from the 18th Dynasty," Minister of Antiquities Khaled al-Anani said. "The two tombs were present with their mummies inside."
