The discovery by a Spanish-Egyptian archaeological team came during excavation work at the tomb of Djehuty, treasure holder for Queen Hatshepsut, at the Dra Abul-Naga necropolis, Ahram Online reported Thursday.
Dubbed the Feathers Sarcophagus for the detailed depictions of bird feather shapes and sizes painted on its lid, the sarcophagus is 6 feet long and 16 inches tall.
It is in very good condition and engraved with titles of the deceased, the particular identity of which has not yet been determined, Egyptian Antiquities Minister Mohamed Ibrahim said.
However, the titles identify it as belonging to a top governmental official from the 17th dynasty whose mummy was found inside, researchers said.
Two other burial sites discovered at the site were both empty, probably robbed in antiquity, they said.
