Archaeologists in Egypt say they've unearthed an ancient pyramid that's believed to be more than 4,000 years old!
They made the exciting discovery in sands at Saqqara, south of the capital, Cairo. The site's already known as one of the most famous burial grounds for rulers of ancient Egypt.
It's the 118th pyramid to be found in Egypt and is thought to have belonged to Queen Sesheshet - mother of King Teti - hundreds of years after the Great Pyramids of Giza were built.
Archaeologists have been digging at the site for two years, but the new pyramid was only discovered about two months ago.
All that's left of it is a five metre-high square-shaped base, but Egypt's top archaeologist Zahi Hawass said the remains would originally have been about three times that height.
In the next few weeks, experts are hoping to enter the pyramid's burial chamber. But they're not expecting to find much, as they think it was probably raided a long time ago.
