Dozens of mummies have been unearthed at an ancient burial site in Upper Egypt, officials said.

Egypt's Minister of Antiquities Khaled El-Enany on Saturday unveiled the discovery in Minya, south of Cairo, which consists of "a maze of tombs" housing more than 40 mummies of men, women and children.

The remains, which have not been identified, were likely from the same upper-middle class family, according to a statement from the antiquities ministry.

"All are in a good conservation condition," the ministry said in the statement. "Some of them were buried inside stone or wooden sarcophagi while others were buried in sands or on the floors of the tombs or inside niches."

Researchers from the ministry and Minya University "stumbled upon" the grave last February at the Tuna el-Gebel archaeological site, which was the necropolis of the ancient city of Hermopolis.

There, they uncovered "a tomb engraved in rock composed of a corridor leading to sloping stairs that opened to a rectangular chamber with a number of burials," according to the ministry.

Fragments of pottery and papyri helped archaeologists date the burial site back to the Ptolemaic era, the last dynasty of ancient Egypt, which lasted from 323 BC to 30 BC.
