Over 200 mummies of cats, over 200 mummies of scarabs, as well as several mummies of cobras and alligators, have been found in the tombs.
The discovery was made by an Egyptian archaeological mission during excavation work that began in April, according to Antiquities Minister Khaled el-Enany.
During the work, archaeologists extracted more than a thousand small amulets from the soil.
To reach the findings, the researchers had to remove more than 350 cubic meters of soil.
