The tombs made of mudbricks were excavated at Bir esh- Shaghala in the Dakhla Oasis of Egypt.
Some of the tombs are quite large containing multiple burial chambers, while some have vaulted roofs and one tomb has a roof built in the shape of a pyramid, researchers said.
Archaeologists from Ministry of Antiquities in Egypt also discovered several artefacts inside the tomb including mummy masks and pieces of inscribed pottery known as ostraca.
Giant containers that may have held olive oil or wine were also found. However, chemical tests will need to be done to confirm the contents.
Located in the Western Desert, about 350 kilometres west of Luxor, the Dakhla Oasis contains a vast amount of archaeological remains that date from prehistoric to modern times. A number of settlements from the Roman era flourished in the Dakhla Oasis.
