The burial chamber most likely belonged to a ruler in a line of kings once lost to history, researchers said. “It’s a new chapter in investigating this dynasty,” one noted.

Archaeologists have discovered the large limestone burial chamber of an unidentified ancient Egyptian pharaoh near the city of Abydos dating to about 3,600 years ago during a chaotic period in Egypt's history.

A 2014 excavation proved the Abydos Dynasty existed. Now, Archaeologists have found a second tomb, but the king's identity remains unknown.
